EPS (Earnings Per Share)
A company's net income divided by its outstanding shares.
In depth
EPS measures profitability on a per-share basis, allowing comparison across companies of different sizes. "Diluted EPS" includes the dilutive effect of stock options and convertible securities. "Adjusted" or "non-GAAP" EPS strips out one-time items management deems non-recurring. Beat/miss vs. analyst consensus drives short-term stock moves.
Example
Company with $1B in profit and 200M shares outstanding has EPS of $5.
