Reading a Stock Quote

The numbers on every quote page, explained.

1. Price & Volume — The first numbers on every quote page: last price, change, day range, bid and ask, volume and average volume, and why volume tells you how much a move really matters.
2. Market Cap — How market capitalization is calculated, what mega, large, mid and small cap mean, and why company size affects how a stock behaves.
3. P/E Ratio — What the price-to-earnings ratio tells you, trailing versus forward P/E, real examples, and why a “cheap” or “expensive” P/E never tells the whole story.
4. EPS — Earnings per share explained: how it’s calculated, basic versus diluted, why growth in EPS matters so much for stock prices, and what can distort it.
5. 52-Week Range — How to read a stock’s 52-week high and low, why stocks near their highs often keep leading, and how to use the range as quick context on any quote.
6. Dividend Yield — How dividend yield is calculated, real yields from well-known companies, and why a very high yield can be a warning sign instead of a bargain.
7. Float & Short Interest — What a stock’s float is, how short interest and days to cover work, real examples, and why heavily shorted stocks can make sudden, violent moves.
