Market & Trading Basics
The market-data basics every investor should know — beta, ranges, volume, momentum.
Beta
A measure of how much a stock tends to move relative to the overall market.
52-Week Range
The lowest and highest prices a stock has traded at over the past 52 weeks (one year).
Moving Average (50 / 200-day)
The average closing price over a recent window (e.g. 50 or 200 days) that smooths out short-term noise to show trend.
Free Float
The portion of a company's shares that is freely available for public trading, excluding locked-up or restricted holdings.
Relative Strength Index
A momentum oscillator from 0 to 100 that gauges whether a stock may be overbought or oversold.
