SIE

1. Trace who receives the financing

Learning goal: Separate primary issuance from later trading.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

The SIE blueprint covers capital markets and market participants [F 2]. For foundational reasoning, ask whether the transaction involves newly issued securities or a transfer of existing securities. A primary transaction raises funds through issuance; a secondary trade transfers an existing holding between investors. The broker or trading venue is not automatically the issuer.

In these toy cases ignore underwriting fees and other costs unless supplied. Cash paid by a new investor and proceeds received by an issuer can differ when a fee is specified. Reading the direction of the security and the cash prevents you from treating every exchange trade as new financing for the company.

Worked example

A toy issuer sells 1,000 newly issued shares at $20; ignore costs. Investor A later sells 100 of those shares to B at $22. Who receives each cash amount?

1. New issue: 1,000×20=$20,000 paid to issuer under the no-cost assumption.
2. Later trade: 100×22=$2,200 paid to A.
3. The later transfer is secondary, not another new issue.
4. The issuer does not receive that secondary-sale amount in this model.

Mental model: Follow security ownership and cash separately.

Common trap: A market participant is not automatically the issuer.

2. Separate ownership from a promised payment

Learning goal: Compare basic equity and debt claims without inventing guarantees.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

Products and risks form the largest SIE blueprint area [F 1, F 2]. In a simplified comparison, common equity is an ownership claim and a bond is a debt claim with contract terms. A scheduled coupon is not proof that payment is risk-free. A possible dividend or price gain should not be treated as a promised fixed return.

Use the terms supplied in a question rather than a slogan that one product is "safe." A bond's maturity, issuer quality and market price matter, while an equity holding can change in value. These lessons avoid a ranking of real products and do not claim all securities in a broad category share the same rights.

Worked example

A toy bond promises $40 annually per $1,000 par; a toy share has no stated dividend. Which annual payment is contractually specified in the problem?

1. Bond terms specify the $40 coupon.
2. No share dividend is supplied, so none is assumed.
3. The coupon rate is 40/1,000=4%.
4. The contractual schedule is not a guarantee that default cannot occur.

Mental model: Identify the claim and its stated terms.

Common trap: A fixed payment schedule does not eliminate risk.

3. Coupon and current yield use different denominators

Learning goal: Use market price only for current yield.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

Bond product and risk concepts are in the SIE outline [F 2]. Coupon rate expresses annual coupon relative to par. Current yield expresses the same annual coupon relative to the current market price. If the price falls while coupon dollars remain fixed, current yield rises. That is a ratio identity, not a prediction that every bond's total return rises.

Current yield is not yield to maturity: it omits the eventual principal gain or loss and time-value structure. A maturity or call yield needs additional terms and a cash-flow calculation. These toy cases deliberately ask current yield only, so no unstated redemption date or reinvestment assumption is introduced.

Worked example

A $1,000-par bond pays 6% annually and trades at $960. Current yield?

1. Annual coupon = 1,000×0.06=$60.
2. Use current price $960, not par.
3. Current yield=60/960=0.0625=6.25%.
4. 6% is the coupon rate; 6.25% is not asserted to be YTM.

Mental model: Name the yield before calculating its denominator.

Common trap: Do not infer maturity yield from current yield.

4. A call payoff is not its profit

Learning goal: Subtract premium and scale only once.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

The SIE includes basic options characteristics [F 2]. In our explicitly simplified long-call model, expiration intrinsic value per share is max(stock price - strike, 0). Profit subtracts premium paid. Every example supplies a 100-share contract multiplier; do not assume this multiplier for all real contracts, adjusted contracts or other products.

Ignore fees and taxes and assume exercise or equivalent realization of intrinsic value at expiration. Before expiration, market option value can differ from intrinsic value, so the formula is not a pricing model. A positive intrinsic value can still produce a net loss if it is smaller than the premium.

Worked example

Call: strike $50, premium $3/share, 100 shares. Expiration stock $58. Net profit?

1. Intrinsic value=max(58-50,0)=$8/share.
2. Net per share=8-3=$5.
3. Contract profit=5×100=$500.
4. Breakeven=$53; maximum loss is the $300 premium under this simplified long-call model.

Mental model: Payoff and profit differ by the premium.

Common trap: An in-the-money call can still have a loss.

5. A put has the opposite price direction

Learning goal: Compute downside protection without claiming a free hedge.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

Options are included in SIE product knowledge [F 2]. Our toy long put has intrinsic value max(strike - stock, 0) per share at expiration. Its price direction differs from a call. Subtract its premium to compute standalone option profit and multiply by the stated contract size.

A put used with shares can offset some downside in this model, but premium is a real cost and the combined position differs from the put alone. No transaction fees, taxes or early-exercise considerations are modeled. Read whether the question asks the option leg, stock leg or whole position before adding numbers.

Worked example

Put strike $30, premium $2/share, 100 shares. Expiration stock $24. Standalone profit?

1. Intrinsic value=max(30-24,0)=$6/share.
2. Subtract $2 premium: $4/share net.
3. Scale by 100: $400.
4. If stock is $32, intrinsic value is zero and the option loss is $200.

Mental model: Match the formula to the option type.

Common trap: Do not calculate combined stock-plus-put profit when only the put is asked.

6. A risk label needs a mechanism

Learning goal: Distinguish default, price and liquidity scenarios.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

The SIE Products and Risks area requires distinguishing sources of risk [F 2]. In a foundational scenario, issuer inability to meet promised payments points to credit/default risk; difficulty finding a buyer on acceptable terms points to liquidity risk. Market price changes are a different issue from whether an issuer pays as promised.

For fixed-payment bond intuition, a higher required market yield can imply a lower price, other terms held fixed. Our toy one-period bond gives a single $105 payoff next year; its present price is 105/(1+r). This model omits default, trading costs and intermediate coupons so the direction can be checked without pretending to value every real bond.

Worked example

Toy bond pays $105 next year with no other cash flows. Compare price at required returns 5% and 10%.

1. At 5%: 105/1.05=$100.
2. At 10%: 105/1.10≈$95.4545.
3. The same future payoff has a lower present price at the higher required return.
4. This isolates rate-price arithmetic; it says nothing about default or actual dealer quotes.

Mental model: Name the mechanism before naming the risk.

Common trap: A simplified valuation model is not a guarantee for a real product.

7. A fund percentage is not a dollar amount

Learning goal: Use the supplied fee base and distinguish holdings from guarantees.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

Fund products and risks are part of the SIE outline [F 2]. An investment pooled into a fund may spread exposure across holdings, but that does not guarantee gains or eliminate every shared market risk. A toy portfolio with several holdings can still fall if all respond to the same adverse event.

When an exercise states a fee rate and base, compute the cost from that base. Actual fund expense assessment and disclosures can be more complex than a one-year multiplication. These questions explicitly assume a constant asset value and a simple annual fee, so their arithmetic is not a quote for a named fund or a rule about all charges.

Worked example

A toy fund holds a constant $10,000 balance and charges a simple 0.8% annual asset fee. Ignore other costs. Fee?

1. Convert rate: 0.8%=0.008.
2. Multiply stated base: 10,000×0.008=$80.
3. This does not model changing daily balances.
4. No other transaction charge or tax is supplied.

Mental model: A percentage must be multiplied by its stated base.

Common trap: Diversification is not a profit guarantee.

8. Orders express instructions, not promised outcomes

Learning goal: Separate a price condition from an execution assumption.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

Trading and accounts are covered in the SIE blueprint [F 2]. In a simple order model, a buy limit specifies a maximum acceptable price, while a market order prioritizes execution at available market prices rather than guaranteeing the displayed price. Actual handling can depend on market and order details; these exercises provide a single toy quote and explicitly assume available quantity.

Even when a price condition is met, a real order is not a promise of a fill; routing, queue position and liquidity matter. We avoid current settlement-cycle assumptions and detailed rule claims. Focus on reading the customer instruction and not turning a chart snapshot into guaranteed execution.

Worked example

Toy buy limit $25 for 100 shares; available offers are $24.80 and $25.20 with sufficient quantity. Which meets the price condition?

1. A buy limit allows prices at or below $25.
2. $24.80 is below the cap.
3. $25.20 is above the cap.
4. Only the $24.80 offer meets the stated price condition; this is not a real fill guarantee.

Mental model: Distinguish instructions, conditions and confirmed outcomes.

Common trap: A limit condition met is not the same as a guaranteed fill.

9. A red flag is a reason to follow procedure

Learning goal: Separate recognition from a legal conclusion.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

The SIE outline includes prohibited activities and regulatory responsibilities [F 2]. A scenario may flag misuse of confidential information or a request to evade documentation. The study skill is recognizing what requires appropriate review, not inventing a legal judgment from incomplete facts or advising a customer how to avoid controls.

Do not transform a red flag into a claim that every suspicious act proves a crime. Record the stated facts and follow the applicable firm process; exact filing thresholds, deadlines and current rule text are outside this module unless verified separately. A practice question about identification is not authorization to act on a real account.

Worked example

A toy employee receives confidential issuer information and is asked to trade before public release. Identify the safe reasoning response.

1. The scenario supplies confidential information and a proposed trade.
2. That combination raises a prohibited-activity concern.
3. Do not treat profit potential as permission.
4. Follow applicable supervisory/compliance procedures; no final legal verdict or deadline is inferred here.

Mental model: Recognize concerns without inventing current rule details.

Common trap: Do not convert an educational scenario into real compliance advice.

10. Passing SIE is not registration

Learning goal: Keep eligibility, score and authority separate.

Practice focus: editorial, not a measured error-frequency claim. This lesson uses original examples.

FINRA states the SIE is open to age 18 or older without firm sponsorship, and results are valid for four years. Passing alone does not authorize securities business; the appropriate qualification exam and association with a member firm are also required [F 1]. A preparation course cannot certify registration or guarantee a pass.

The exam has 75 scored questions and 10 unidentified pretest questions, 105 minutes and a passing scaled score of 70 [F 1, F 2]. Do not treat 70 as an invented raw number correct. At test centers it is closed-book, with a provided four-function calculator and erasable boards; restroom breaks do not stop the timer [F 5]. These rules do not describe remote-testing procedures.

Worked example

An applicant passes SIE without firm association. What can be concluded, and how many items were presented?

1. Passing establishes the SIE result, not securities-business authority.
2. Further qualification and firm association requirements remain.
3. Presented items=75+10=85.
4. The unidentified pretest status does not justify treating known items as skippable.

Mental model: Eligibility, scaled scoring and authority are distinct.

Common trap: Do not invent a raw pass table or promise registration.

11. Net asset value is a per-share calculation

Learning goal: Separate total net assets from value per outstanding share.

Net asset value per share is a ratio. In a simplified fund balance sheet, subtract liabilities from assets to obtain net assets, then divide by shares outstanding. FINRA includes net asset value and investment-company products in the SIE outline. The calculation is a teaching model, not a live fund quote, a sale recommendation or a statement of transaction pricing for every product.

Original case: assets are 1200 units, liabilities are 200 and one hundred shares are outstanding. Net assets equal one thousand and net asset value per share equals ten. Dividing gross assets by shares gives twelve, which ignores liabilities. Dividing liabilities by shares gives two, which is not the requested measure. Label every numerator before calculating.

A change in shares outstanding needs a corresponding accounting context. A purely proportional increase in both net assets and shares can leave per-share value unchanged. Do not infer that more shares always means each share is worth less. Similarly, a market price for a traded closed-end fund can differ from net asset value; the valuation measure is not automatically an executable market price.

Practice set: assets 2400, liabilities 400, shares two hundred. Per-share net asset value remains ten. Then hold the net assets at two thousand but use 250 shares; per-share value is eight. These are different hypothetical balance sheets. Explain what changed rather than treating the same ratio as a universal trend. Read product terms and current official rules separately before interpreting a real fund transaction.

Source alignment: [F 2]. All numerical data and practice questions here are original teaching examples, not official exam questions or observed results.

Worked example

Assets 1200, liabilities 200, shares 100. Calculate NAV per share.

1. Subtract liabilities from assets.
2. Net assets=1000.
3. Divide by 100 shares.
4. NAV per share=10.

Mental model: Separate total net assets from value per outstanding share.

Common trap: Use gross assets rather than net assets.

12. A stock split changes units, not modeled total value

Learning goal: Track share count and per-share price together under an explicit no-market-move assumption.

A stock split changes the units in which ownership is represented. Under a simplified two-for-one split with no market movement, twice as many shares correspond to half the modeled price per share. The total position value stays the same in that model. Real prices can move for other reasons; the arithmetic does not promise a trading result.

Original position: one hundred shares at forty units each, worth four thousand. After a two-for-one split, the holder has two hundred shares. At the theoretical adjusted price of twenty, the total is still four thousand. Looking only at the falling per-share price can incorrectly suggest a fifty percent loss. Looking only at the doubled share count can incorrectly suggest doubled wealth.

FINRA includes equity products and stock-related corporate actions in its content scope. For an exercise, state the split ratio and whether the question holds total value constant. Reverse splits combine units rather than divide them. Product notices and actual execution prices govern real positions, and other corporate actions can have different effects.

Practice set: sixty shares at ninety become 180 shares after a three-for-one split. The theoretical price is thirty and total value remains 5400. Next, two hundred shares at five become fifty shares in a one-for-four reverse split; the theoretical price is twenty and total value one thousand. Each result depends on the no-market-move teaching assumption. Track units and value in separate columns.

Source alignment: [F 2]. All numerical data and practice questions here are original teaching examples, not official exam questions or observed results.

Worked example

100 shares at 40, two-for-one split, no market change. Find new shares.

1. Multiply shares by 2.
2. 100×2=200 shares.
3. Theoretical price halves to 20.
4. Total modeled value stays 4000.

Mental model: Track share count and per-share price together under an explicit no-market-move assumption.

Common trap: Treat a change in units as a change in total wealth.

13. Inflation changes purchasing power

Learning goal: Distinguish a nominal growth factor from a real purchasing-power factor.

A nominal return describes change in money units. Purchasing power also depends on price changes. In a simple one-period model, divide the ending nominal-value factor by the price-level factor to obtain the real-value factor. Subtract one to express a real return. The familiar nominal-minus-inflation calculation is an approximation, not the exact ratio.

Original example: a balance grows five percent while the price level rises five percent. Both factors are 1.05, so their ratio is one and real purchasing power is unchanged in the model. If nominal growth is ten percent and prices grow five percent, the real factor is 1.10/1.05, about 1.0476. The real return is about 4.76 percent, not exactly five percent.

FINRA includes investment risks and return components in its outline. This lesson uses a general inflation model, not a forecast of actual inflation or a recommendation about securities. A particular investor consumption basket can differ from a published price index, and taxes or fees can change the nominal amount retained. State what the model excludes.

Practice set: nominal value rises twenty percent and the price level rises ten percent. The real factor is 1.2/1.1, or about 1.0909. Next, nominal value is unchanged while prices rise twenty-five percent. The real factor is 1/1.25=0.8, a twenty percent real decline. A larger money balance does not by itself prove improved purchasing power. Use factors rather than subtracting percentages without explanation.

Source alignment: [F 2]. All numerical data and practice questions here are original teaching examples, not official exam questions or observed results.

Worked example

Nominal factor 1.05, price factor 1.05. Find real factor.

1. Divide nominal by price factor.
2. 1.05/1.05=1.
3. Real purchasing power is unchanged.
4. No forecast is implied.

Mental model: Distinguish a nominal growth factor from a real purchasing-power factor.

Common trap: Treat nominal growth as real growth.

14. Diversification is not a promise of loss-free returns

Learning goal: Distinguish concentration risk from a guarantee about the whole portfolio.

Diversification spreads exposure across holdings or risk sources. It is not a promise that every possible loss disappears. FINRA includes diversification and investment risks in the SIE scope. A portfolio can remain exposed to broad market moves even if one issuer failure has less effect than it would in a single-stock position.

Original model: half the portfolio is in A and half in B. If A loses twenty percent while B is unchanged, the total loses ten percent before fees. The smaller loss than a portfolio entirely in A shows the effect of this allocation in this scenario. It does not establish that B will remain stable in all scenarios or that the allocation is suitable for a real investor.

If A and B both lose twenty percent, the same equal-weight portfolio loses twenty percent. Holding two assets does not help this particular outcome because both move together. Diversification depends on exposures and relationships, not just the count of ticker symbols. A collection of similar sector holdings may share risks despite having many names.

Practice set: weights are one-quarter in A and three-quarters in B. Returns are minus twenty and plus four percent. The weighted return is minus five plus three, or minus two percent. Then set both returns to plus ten: the portfolio earns ten percent. Keep beginning weights and the period consistent in this simplified arithmetic. Do not infer future correlations or a guaranteed outcome from these invented cases.

Source alignment: [F 2]. All numerical data and practice questions here are original teaching examples, not official exam questions or observed results.

Worked example

Weights 50/50, returns -20% and 0%. Calculate portfolio return.

1. Use beginning weights.
2. 0.5×(-20%)=-10%.
3. 0.5×0%=0%.
4. Total=-10%.

Mental model: Distinguish concentration risk from a guarantee about the whole portfolio.

Common trap: Treat asset count as a loss guarantee.

15. A bid-ask spread is not the same as an investment return

Learning goal: Use the correct side of a hypothetical quote for an immediate buy or sell.

A bid is a price at which a quoting buyer is willing to buy; an ask is a price at which a quoting seller is willing to sell. In a simplified immediate execution model, a customer buying uses the ask and a customer selling uses the bid. FINRA covers markets and trading terminology. Actual order execution can differ, and a displayed quote is not an unconditional promise for every size or venue.

Original quote: bid nine, ask ten. Buying one hundred shares at the ask costs one thousand before fees. Selling them immediately at the same bid returns nine hundred. The hundred-unit difference reflects crossing the unchanged spread in this toy model. It is not a measured trading cost for a live security and does not include commissions or price movement.

Do not compare both legs at the midpoint unless the question explicitly grants midpoint execution. A quoted bid and ask also have sizes and conditions in real markets. A large order may not fill entirely at one displayed price. Market and limit orders express different instructions; neither quote arithmetic nor a limit alone guarantees full execution.

Practice set: bid nineteen, ask twenty, quantity fifty. The toy round trip costs one thousand and returns 950, producing a fifty-unit difference before fees. Change the quote after purchase and recompute instead of assuming the spread stays fixed. The lesson teaches terminology and direction; it does not recommend rapid trading or imply an achievable arbitrage.

Source alignment: [F 2]. All numerical data and practice questions here are original teaching examples, not official exam questions or observed results.

Worked example

Bid 9,ask 10,buy 100 at ask. Find cost before fees.

1. A buy crosses to the ask in this model.
2. Use ask 10,not bid 9.
3. 100×10=1000.
4. Fees are excluded.

Mental model: Use the correct side of a hypothetical quote for an immediate buy or sell.

Common trap: Price both legs at the same quote side.

16. Mixed market practice keeps each measure separate

Learning goal: Audit a short set using balance-sheet, quote and risk definitions.

This original mixed set combines a fund valuation, a bid-ask calculation and portfolio returns. They use different denominators and different assumptions. A fund net asset value is a balance-sheet ratio, a quote is a trading indication, and a portfolio return combines weighted changes. None should be used as a substitute for the others.

First, fund assets are 1200, liabilities 200 and shares 100. Calculate net asset value per share. Second, a bid of nine and ask of ten apply to a hypothetical hundred-share round trip with unchanged prices and no fees. Calculate the difference. Third, an equal-weight portfolio contains returns minus twenty and zero percent. Calculate its period return.

The answers are ten, one hundred, and minus ten percent. The first subtracts liabilities; the second buys at ask and sells at bid under the specified model; the third uses beginning weights. The arithmetic is independent of whether a real fund trades at net asset value or a real order receives the quoted execution. Do not import a transaction rule that the exercise does not state.

For a fresh pass, use net assets of two thousand and shares 250, a bid nineteen and ask twenty for fifty shares, and weights one-quarter/three-quarters with returns minus twenty and plus four percent. The answers are eight, fifty, and minus two percent. Review each mistaken result by definition or assumption. These are not official SIE questions, a score predictor or investment advice. Use the FINRA outline separately for full scope and current rule-sensitive requirements.

Source alignment: [F 2]. All numerical data and practice questions here are original teaching examples, not official exam questions or observed results.

Worked example

Assets 1200,liabilities 200,shares 100. Find NAV/share.

1. Subtract liabilities.
2. Net assets 1000.
3. Divide by 100.
4. NAV/share 10.

Mental model: Audit a short set using balance-sheet, quote and risk definitions.

Common trap: Use one market number to answer a different financial measure.
