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 and PEG aren't shown here — both need historical analyst-consensus estimates, which no free source provides; see the current-period figures above instead.

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.

Signals describe daily price patterns—not the company’s value and not a recommendation to buy or sell. Read several together; no single indicator predicts what happens next. “Overbought” and “oversold” are conditions, not promises of a reversal.

Free IEX historical data only goes back to ~2021 — 5Y/Full show whatever's actually available, not a promise of that much history. Indicators are computed client-side from these same price bars; earnings markers ("E") come from Finnhub's free tier (~last 4 quarters + next upcoming) — older quarters aren't available. The move-highlight dots are a heuristic (|% change| vs rolling volatility) with a best-effort headline lookup, not a claim of causation.

Rule-based facts only; absence from either side is not evidence, and this is not a recommendation.
