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.

Technical signal summary
Calculating from the latest year of daily price history…
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.
Indicators None active
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.
Peer and sector context
Balanced evidence
A deterministic summary of sourced facts—not an AI verdict.
Potential strengths
- Revenue growth is 39.5% on the provider's reported measure. Finnhub fundamentals ↗
- Trailing 52-week price return is +273.5%. Finnhub market metrics ↗
Potential concerns
- Net profit margin is 7.9%. Finnhub fundamentals ↗
- Trailing P/E is 143.0, a high price relative to reported earnings. Finnhub fundamentals ↗
- Latest SEC filing is Form 8-K, filed 2026-09-03; review it for current changes and risks. SEC EDGAR ↗
Rule-based facts only; absence from either side is not evidence, and this is not a recommendation.
