How to Read a Stock Quote
Pull up any stock and you get a wall of numbers. Good news: only a handful of them matter, and each answers one plain question. Ten minutes here and you'll read any quote page like a second language.
A $900 stock is not 'more expensive' than a $9 one in any meaningful way — the price per share depends entirely on how many slices the company cut itself into. The single most common beginner error is treating share price as a size or a quality. It's neither. It's just a slice size.
Share price times number of shares equals market capitalization — what the whole business is valued at. THIS is the number for comparing companies. A $9 stock with billions of shares can be a giant; a $900 stock can be a minnow. Always convert to the whole-business number before your brain forms an opinion.
Volume counts shares traded today. Its real use is context: a big price move on heavy volume means the crowd showed up with conviction; the same move on a trickle means a few trades in a quiet room. Learn a name's normal volume, and 'unusual' starts jumping out at you — a skill an entire later course is built on.
The price-to-earnings ratio divides the price by yearly profit per share. A P/E of 20 means you're paying twenty years of current profits for the business. High P/E means the crowd expects profits to grow fast; low means modest expectations — or trouble. It's not a verdict, it's a question: what am I being asked to believe?
The high and low of the past year show you how widely opinion has swung on this same business. It's a humility gauge: the identical company was priced at both ends within twelve months. Whatever certainty you feel about today's price, someone felt it at both of those, too.
Market cap for size, volume for conviction, P/E for expectations, the range for humility — and share price for almost nothing. That's the quote page, translated.
