Preferred stock and common stock are the two main types of equity securities issued by corporations. Understanding the differences between them is critical for the FINRA SIE Exam, as questions frequently test features, investor priorities, risks, and situations where one is preferable over the other. This section covers the structural differences, rights, dividend treatments, and comparative characteristics that appear on the exam.
Common stock represents ownership in a corporation and gives shareholders voting rights and potential appreciation. Common stockholders are the last in line for claims on company assets and dividends-they get paid only after all debts and preferred stockholders are satisfied.
Key Features:
Preferred stock is a hybrid security combining features of both equity and debt. It pays a fixed dividend (stated as a dollar amount or percentage of par value) and has priority over common stock for dividend payments and asset distribution in liquidation, but typically carries no voting rights.
Key Features:
Cumulative preferred stock requires that any skipped (unpaid) dividends accumulate and must be paid in full before any dividends can be paid to common stockholders. Non-cumulative preferred stock does not accumulate unpaid dividends; if a dividend is skipped, it is lost forever.
Key Facts:
Callable preferred stock gives the issuing corporation the right to repurchase the shares at a predetermined call price after a specified date. This benefits the issuer when interest rates decline, as they can retire high-dividend preferred and reissue at lower rates.
Key Facts:
Convertible preferred stock allows the holder to exchange preferred shares for a fixed number of common shares at the investor's option. The conversion ratio determines how many common shares the investor receives per preferred share.
Key Facts:
Parity Price Calculation:
To find when conversion is profitable:
\( \text{Parity price of preferred} = \text{Common stock market price} \times \text{Conversion ratio} \)
Example: Preferred converts to 5 shares of common. Common trades at $22.
\( \text{Parity price} = 22 \times 5 = 110 \)
If preferred trades above $110, don't convert. If below $110, conversion is profitable.
Participating preferred stock receives its fixed dividend plus the opportunity to receive additional dividends if common stockholders receive dividends above a certain level. This feature is rare but testable.
Key Facts:

1. Scenario: A company has not paid dividends for three years. It now declares a dividend. The question asks who receives payment first among common shareholders, cumulative preferred shareholders, and bondholders.
Correct Approach: Bondholders receive interest first (debt obligation), then cumulative preferred receives all three years of arrears plus current year dividend, then common shareholders if funds remain.
Check first: Whether the preferred stock is cumulative or non-cumulative-only cumulative preferred accumulates arrears.
Do NOT do first: Assume preferred and common shareholders are paid simultaneously or that missing the order of priority. Dividends are never paid to common if cumulative preferred has arrears.
Why other options are wrong: Common stockholders cannot receive dividends before preferred arrears are cleared; non-cumulative preferred would not have arrears to collect; bondholders receive interest payments, not dividends, and always come before equity holders.
2. Scenario: Interest rates in the market increase significantly. A question asks which security will likely experience the greatest decline in market price: common stock or preferred stock.
Correct Approach: Preferred stock will decline more predictably because it has a fixed dividend and trades like a bond-price moves inversely with interest rates.
Check first: Recognize that preferred stock is interest-rate sensitive due to its fixed-income characteristics.
Do NOT do first: Choose common stock based on general volatility-while common is more volatile overall, the question specifically tests the interest rate relationship.
Why other options are wrong: Common stock may be affected by many factors beyond interest rates; preferred stock's fixed dividend makes it directly comparable to newly issued securities at higher rates, forcing its price down to maintain competitive yield.
3. Scenario: An investor owns convertible preferred stock with a conversion ratio of 5:1 and par value of $100. Common stock is trading at $18. The question asks if the investor should convert.
Correct Approach: Calculate parity price: \( 18 \times 5 = 90 \). If the preferred trades above $90, do not convert; if below $90, conversion is profitable.
Check first: Calculate the parity price by multiplying common stock price by the conversion ratio before deciding.
Do NOT do first: Convert immediately without calculating parity or assume conversion is always beneficial because common stock "might" appreciate later.
Why other options are wrong: Converting when preferred trades above parity results in immediate loss; holding common stock hoping for appreciation introduces more risk than maintaining the preferred dividend; ignoring the conversion price or ratio leads to incorrect valuation.
4. Scenario: A corporation announces it will call its 6% preferred stock currently trading at $105 at a call price of $102. The question asks what happens to investors.
Correct Approach: Investors receive $102 per share (the call price), which is a loss from the current market price of $105, and they face reinvestment risk as they must reinvest proceeds at lower prevailing rates.
Check first: Identify the call price versus the current market price to determine if investors gain or lose from the call.
Do NOT do first: Assume investors benefit from a call or that they receive the current market price-the issuer pays only the stated call price.
Why other options are wrong: Investors do not receive market price; the call benefits the issuer by retiring expensive dividend obligations; refusing the call is not an option once the issuer exercises the call right.
5. Scenario: In a bankruptcy liquidation, a question asks the order of payment among common stockholders, preferred stockholders, secured bondholders, and unsecured bondholders.
Correct Approach: Secured bondholders first, unsecured bondholders second, preferred stockholders third, common stockholders last.
Check first: Distinguish between debt holders (all creditors) and equity holders (preferred and common)-debt always comes before equity.
Do NOT do first: Place any equity holder before any debt holder or assume preferred stockholders have priority over creditors.
Why other options are wrong: Common stockholders always come last; preferred stockholders, despite priority over common, cannot be paid until all debt obligations are satisfied; secured creditors have specific collateral claims and come before unsecured creditors.
Task: Determine if a convertible preferred stock should be converted to common stock
Task: Calculate annual dividend payment for preferred stock
Task: Determine total payment to cumulative preferred with dividends in arrears
Q1: An investor owns 100 shares of 5% cumulative preferred stock with a $100 par value. The company skipped dividends for the past two years but now declares a dividend. How much must the investor receive before any common shareholders are paid?
(a) $500
(b) $1,000
(c) $1,500
(d) $2,000
Ans: (c)
Annual dividend = $100 par × 5% = $5 per share. Two years arrears = $5 × 2 = $10 per share. Current year = $5. Total = $15 per share × 100 shares = $1,500. (a) represents only one year; (b) represents two years without current; (d) represents four years.
Q2: Which of the following statements is TRUE regarding preferred stock?
(a) Preferred stockholders have voting rights equal to common stockholders
(b) Preferred stock dividends must be paid before common stock dividends
(c) Preferred stock has unlimited capital appreciation potential
(d) Preferred stock is unaffected by changes in interest rates
Ans: (b)
Preferred dividends are paid before common dividends, though neither is guaranteed. (a) is incorrect-preferred typically has no voting rights; (c) is incorrect-preferred has limited upside, trading near par; (d) is incorrect-preferred is highly sensitive to interest rate changes, similar to bonds.
Q3: An investor owns convertible preferred stock with a par value of $100 and a conversion ratio of 4:1. If the common stock is trading at $28 per share and the preferred is trading at $115, what should the investor do?
(a) Convert immediately because common stock is rising
(b) Hold the preferred because it is trading below parity
(c) Convert because the preferred is trading above parity
(d) Hold the preferred because it is trading above parity
Ans: (d)
Parity price = $28 × 4 = $112. The preferred trades at $115, which is above parity, so converting would result in a loss ($115 preferred vs. $112 worth of common). Hold the preferred. (a) ignores parity calculation; (b) has the parity relationship backwards; (c) incorrectly suggests converting when above parity, which would create a loss.
Q4: Interest rates in the market decline significantly. Which preferred stock is a corporation most likely to call?
(a) Non-callable preferred with a 3% dividend
(b) Callable preferred with a 7% dividend
(c) Convertible preferred with a 4% dividend
(d) Cumulative preferred with dividends in arrears
Ans: (b)
When interest rates decline, issuers call high-dividend callable preferred to refinance at lower rates. The 7% callable preferred costs the issuer the most and is the best candidate for calling. (a) is non-callable, so cannot be called; (c) convertible preferred typically has lower yields and may not be called if conversion value is high; (d) dividends in arrears do not make a preferred more likely to be called.
Q5: In a corporate liquidation, which of the following has the highest priority claim on assets?
(a) Common stockholders
(b) Preferred stockholders
(c) Unsecured bondholders
(d) Subordinated debenture holders
Ans: (c)
All creditors (debt holders) are paid before any equity holders. Unsecured bondholders come before preferred and common stockholders. Among the choices, (c) has highest priority. (a) and (b) are equity and come last; (d) subordinated debt is junior to unsecured but still senior to equity.
Q6: Which of the following investors would be MOST suitable for preferred stock?
(a) An aggressive investor seeking maximum capital gains
(b) A conservative investor seeking steady income
(c) A young investor with a long time horizon seeking growth
(d) A speculative investor willing to accept high volatility
Ans: (b)
Preferred stock provides fixed income with less volatility, making it suitable for conservative, income-oriented investors. (a), (c), and (d) all describe growth- or speculation-oriented investors who would be better served by common stock or more aggressive investments.
