Trailing-twelve-month ratios computed from SEC EDGAR quarterly figures and historical daily close prices (Alpaca). Diluted shares are derived from Net income ÷ EPS (diluted) for each quarter, not separately reported. Forward P/E/PEG unavailable (no free data source).

Glossary — what these abbreviations mean
1. TTM
Trailing twelve months — the sum of the last four reported quarters, not a calendar year or the single latest quarter.
2. EPS
Earnings per share — net income divided by diluted shares outstanding.
3. Beta
A stock's historical volatility relative to the overall market. Above 1 means it has moved more than the market; below 1, less.
4. EV (Enterprise Value)
Market cap plus total debt minus cash — roughly what it would cost to buy the whole company, debt included.
5. Forward P/E
Price divided by analysts' estimated earnings for the next 12 months, instead of trailing actual earnings.
6. PEG Ratio
P/E divided by expected earnings growth rate. A lower number can indicate a stock is cheap relative to how fast it's expected to grow.
7. Price / Book
Share price divided by book value (assets minus liabilities) per share.
8. ROE
Return on equity — net income divided by shareholders' equity, a measure of how efficiently a company turns equity into profit.
9. ROA
Return on assets — net income divided by total assets, a measure of how efficiently a company turns assets into profit.
10. MRQ
Most recent quarter — the single latest reported period, as opposed to TTM. The Financials section's "Quarterly" view below shows MRQ-style figures.
11. YoY
Year over year — percent change versus the same period one year earlier, used for growth figures like those on Compare cards and the Screener.
