Document 4: Key Stock Market Indicators
Stock market indicators are statistical measures used to gauge the overall health, direction, and
sentiment of the market. They help investors and analysts understand market trends and make
informed decisions.
Major Stock Market Indices
Stock market indices are hypothetical portfolios of stocks that represent a particular market or
segment of the market. They are crucial for tracking performance:
1. Dow Jones Industrial Average (DJIA):
Composition: A price-weighted average of 30 significant publicly traded companies in the
United States. It includes "blue-chip" companies like Apple, Microsoft, and Coca-Cola.
Significance: One of the oldest and most widely cited indices, often used as a general
indicator of the U.S. stock market's health.
Limitation: Because it's price-weighted, higher-priced stocks have a greater impact on
the index, regardless of their market capitalization.
2. S&P 500 (Standard & Poor's 500):
Composition: A market-capitalization-weighted index of 500 of the largest U.S. publicly
traded companies. It covers a broader range of industries than the Dow.
Significance: Widely considered the best gauge of large-cap U.S. equities and a strong
indicator of the overall U.S. stock market's performance.
Weighting: Companies with larger market capitalizations have a greater influence on the
index's value.
3. Nasdaq Composite:
Composition: A market-capitalization-weighted index of all common stocks and similar
securities listed on the Nasdaq stock market. It is heavily weighted towards technology
and growth companies.
Significance: Often used to track the performance of the technology sector and smaller
growth companies.
4. Russell 2000 Index:
Composition: A market-capitalization-weighted index of the smallest 2,000 companies in
the broader Russell 3000 Index.
Significance: Serves as a benchmark for small-cap U.S. stocks, often seen as an
indicator of the health of smaller, domestically focused businesses.
Key Valuation Metrics
These metrics help investors assess whether a stock is overvalued, undervalued, or fairly priced:
1. Price-to-Earnings (P/E) Ratio:
Formula: Share Price / Earnings Per Share (EPS)
Meaning: Indicates how much investors are willing to pay for each dollar of a company's
earnings. A high P/E ratio might suggest investors expect high future growth, while a low
P/E might indicate an undervalued stock or a company with limited growth prospects.
Usage: Often compared to a company's historical P/E, its industry average, or the
broader market P/E.
2. Earnings Per Share (EPS):

Formula: (Net Income - Preferred Dividends) / Number of Common Shares Outstanding
Meaning: The portion of a company's profit allocated to each outstanding share of
common stock. A higher EPS generally indicates greater profitability.
3. Dividend Yield:
Formula: Annual Dividends Per Share / Share Price
Meaning: The percentage return an investor receives in dividends relative to the stock's
price. Useful for income-focused investors.
4. Market Capitalization (Market Cap):
Formula: Share Price × Number of Outstanding Shares
Meaning: The total value of a company's outstanding shares. It indicates the company's
size. Companies are often categorized as large-cap, mid-cap, or small-cap based on their
market cap.
5. Price-to-Book (P/B) Ratio:
Formula: Share Price / Book Value Per Share
Meaning: Compares a company's market value to its book value (assets minus
liabilities). A P/B ratio less than 1 might suggest an undervalued stock, while a higher ratio
could indicate that investors believe the company's assets are worth more than their
accounting value.
Other Important Indicators
Volume: The number of shares traded in a security or market during a given period. High
volume often accompanies significant price movements, indicating strong conviction among
traders.
Volatility Indices (e.g., VIX - CBOE Volatility Index): Measures the market's expectation of
future volatility, based on S&P 500 options. A higher VIX often indicates greater market fear or
uncertainty.
Economic Indicators: Broader economic data like GDP growth, inflation rates, interest rates,
unemployment rates, and consumer confidence can significantly influence stock market
performance.
