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.

Show Technical Analysis Breakdown ▾ 10 Indicators
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.

Loading chart…
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.

Potential strengths

- Latest SEC filing is Form 4, filed 2026-07-10; review it for current changes and risks. SEC EDGAR ↗
Potential concerns
- Net profit margin is -17.2%. Finnhub fundamentals ↗
- Trailing 52-week price return is -15.4%. Finnhub market metrics ↗
