Market Capitalization
Market Capitalization
The total market value of all outstanding shares of a company, calculated by multiplying the current share price by shares outstanding. Classification by size: Large-cap (over $10 billion), Mid-cap ($2-10 billion), Small-cap ($300 million to $2 billion), Micro-cap (under $300 million). Used extensively in portfolio construction and index weighting.
A company with 50 million shares outstanding trading at $80 per share has a market capitalization of $4 billion (50M × $80 = $4B), classifying it as a mid-cap stock. If the stock price rises to $100, market cap increases to $5 billion without any change to the underlying business.
Market cap is often confused with enterprise value (which includes debt and excludes cash). Students also mistake market cap for company book value or annual revenue. Additionally, size categories (large-cap, mid-cap, small-cap) have no official regulatory definitions and can vary slightly by index provider.
How This Is Tested
- Calculating market capitalization using share price and shares outstanding
- Classifying stocks into large-cap, mid-cap, or small-cap categories based on market value
- Understanding how market cap changes with stock price movements
- Determining appropriate portfolio allocation by market cap for different client risk profiles
- Recognizing that small-cap stocks typically have higher volatility and growth potential than large-cap stocks
Calculation Example
Market Capitalization = Share Price × Shares Outstanding - Identify the current share price: $120
- Identify shares outstanding: 25 million
- Multiply: $120 × 25,000,000 shares
- Calculate result: $3,000,000,000 or $3 billion
- Classify: $3 billion falls in the mid-cap range ($2B-$10B)
Regulatory Limits
| Description | Limit | Notes |
|---|---|---|
| Large-cap classification | Over $10 billion | Typically established, lower-risk companies with stable earnings |
| Mid-cap classification | $2 billion to $10 billion | Growth-oriented companies with moderate risk and return potential |
| Small-cap classification | $300 million to $2 billion | Higher growth potential but greater volatility and risk |
| Micro-cap classification | Under $300 million | Highest risk, often illiquid and speculative |
Example Exam Questions
Test your understanding with these practice questions. Select an answer to see the explanation.
Marcus, age 35 with high risk tolerance and a 30-year investment horizon, currently has a portfolio allocated 100% to large-cap U.S. stocks. He wants to increase growth potential while maintaining diversification. Which of the following adjustments would be most appropriate for his situation?
A is correct. Given Marcus's high risk tolerance, long time horizon (30 years), and desire for increased growth potential, adding a 20% allocation to small-cap stocks provides exposure to higher growth opportunities while maintaining diversification through his remaining 80% large-cap position. Small-cap stocks historically offer higher growth potential with increased volatility, which Marcus can tolerate given his risk profile and time horizon.
B is incorrect because maintaining 100% large-cap doesn't address his goal of increasing growth potential. C is incorrect because Marcus has high risk tolerance and doesn't need bond allocation for volatility reduction (and the question states he wants to increase growth, not reduce risk). D is incorrect because eliminating all large-cap holdings removes important diversification and creates excessive concentration risk, even for a high-risk-tolerance investor.
The Series 65 exam tests your ability to recommend appropriate market cap allocations based on client risk tolerance, time horizon, and investment objectives. Understanding the risk-return characteristics of different market cap categories is essential for portfolio construction and suitability analysis.
Which of the following best describes a small-cap stock?
A is correct. Small-cap stocks are defined by market capitalization (share price × shares outstanding) under $2 billion. This classification focuses on market value, not operational metrics like revenue or employees.
B ($10 billion) describes the upper threshold for mid-cap stocks, not small-cap. C (annual revenue) and D (employee count) are not how market capitalization categories are defined. Market cap is strictly a function of stock price times shares outstanding, representing the total market value of the company.
The Series 65 exam frequently tests knowledge of market cap size categories ($2B threshold for small-cap, $10B for large-cap). Understanding these classifications is critical for portfolio construction questions and explaining investment strategies to clients.

Access Free BetaA company has 40 million shares outstanding and is trading at $75 per share. What is the market capitalization of this company?
C is correct. Calculate: Market Cap = Share Price × Shares Outstanding = $75 × 40,000,000 shares = $3,000,000,000 = $3.0 billion. This would classify as a mid-cap stock (between $2B and $10B).
A ($1.5B) incorrectly divides instead of multiplying, or uses half the shares. B ($2.0B) appears to miscalculate the number of shares or price. D ($4.0B) might result from using incorrect share price ($100 instead of $75). Always multiply the current share price by total shares outstanding to get market cap.
Market capitalization calculation questions are common on the Series 65 exam. You must accurately apply the formula (Share Price × Shares Outstanding) and correctly convert millions to billions. This calculation is fundamental to understanding company valuation and portfolio composition.
All of the following statements about market capitalization are accurate EXCEPT
C is correct (the EXCEPT answer). Market capitalization does NOT remain constant. It fluctuates continuously with stock price changes. Since market cap = share price × shares outstanding, any change in share price directly changes market cap (assuming shares outstanding remain constant). A 10% stock price increase results in a 10% market cap increase.
A is accurate: the formula is indeed Share Price × Shares Outstanding. B is accurate: small-cap stocks typically have higher volatility due to less liquidity, smaller business scale, and greater sensitivity to market changes. D is accurate: large-cap stocks are generally defined as having market capitalization over $10 billion.
The Series 65 exam tests your understanding that market cap is a dynamic measure that changes with stock price movements. This is critical for explaining to clients how portfolio composition can shift over time as stock prices change, even without buying or selling securities.
An investor is comparing two stocks: Stock X has a market cap of $15 billion, and Stock Y has a market cap of $1.5 billion. Which of the following statements are accurate?
1. Stock X would be classified as large-cap
2. Stock Y would be classified as mid-cap
3. Stock Y likely has higher growth potential but greater volatility
4. Stock X likely provides more stable returns with lower growth potential
C is correct. Statements 1, 3, and 4 are accurate.
Statement 1 is TRUE: Stock X at $15 billion exceeds the $10 billion threshold for large-cap classification.
Statement 2 is FALSE: Stock Y at $1.5 billion is below the $2 billion threshold, classifying it as small-cap, not mid-cap. Mid-cap stocks range from $2B to $10B.
Statement 3 is TRUE: Small-cap stocks (like Stock Y) typically offer higher growth potential because they have more room to expand, but they also exhibit greater volatility due to less established business models, lower liquidity, and greater sensitivity to market conditions.
Statement 4 is TRUE: Large-cap stocks (like Stock X) generally provide more stable, predictable returns because they are established companies with proven business models, but typically offer lower growth rates than smaller companies.
The Series 65 exam tests detailed knowledge of market cap classifications and their risk-return characteristics. Understanding the threshold values ($2B for small/mid boundary, $10B for mid/large boundary) and associated risk profiles is critical for portfolio construction and making suitable recommendations based on client objectives and risk tolerance.
💡 Memory Aid
Think "Cap = Company Price Tag": Market cap is the price tag the market puts on the entire company. Small stores (under $2B) grow fast but risky. Department stores ($2-10B) balance growth and stability. Mega-malls (over $10B) are stable giants. The price tag changes every second with the stock price.
