Key ideas in The Stock Market and Business Fundamentals
- A share of stock is not just a digital betting chip; it represents legal fractional ownership of an operating business
- Stockholders hold a proportional claim on corporate assets and future profits, which can be paid out as dividends or reinvested to grow the company
- A market order prioritizes speed, filling instantly at the best available current market price
- A limit order prioritizes price control, specifying an exact price cap or floor, but may never fill if the market moves away
- Fast-moving markets can cause market orders to fill at prices noticeably different from the last quote displayed
- The 'ask' is the lowest price sellers will accept right now, and the 'bid' is the highest price buyers are willing to pay
- Market buyers pay the ask price while market sellers receive the lower bid price
- The gap between the bid and ask (the spread) is a built-in transaction cost absorbed immediately upon trading
- Fractional shares allow investors to buy fractions of a single share based on a specific dollar budget (dollar-based investing)
- A high per-share price (like $500 or $3,000) is no longer a barrier for beginning investors with small budgets
- Fractional shares earn the same proportional percentage returns and dividend payouts as whole shares
- A ticker symbol is just the shorthand code used to look up a specific company on a stock exchange
- Daily share prices move based on what buyers and sellers collectively expect to happen in the future, not just what the company earned that morning
- A company's day-to-day operations can remain completely steady while its stock price fluctuates wildly on news or sentiment
- Market capitalization is the total dollar value of the whole company, calculated by multiplying the share price by the total number of shares
- Looking at share price alone tells you what one slice costs, not how big the whole pie is
