You don’t need to memorize everything. You just need the handful of terms that show up constantly.
1) Market cap
A quick way to compare company size (but not value).
2) Volume
How much trading activity a stock sees. Spikes can matter.
3) Float
Shares available to trade. Float affects volatility.
4) P/E
A common valuation shorthand—useful, but easy to misuse.
5) Revenue vs. earnings
Top line vs. bottom line. Both matter, for different reasons.
