Earnings Trends (Quarterly EPS Actual vs Estimate)
Valuation Measures & Ratios
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.
Short Interest
Source: FINRA Rule 4560 consolidated short interest, settlement date 2026-08-14. Reported bi-monthly with a reporting lag — not real-time.
Quotes and the 1-day extended-hours chart: Yahoo Finance. Longer historical charts: Alpaca (IEX feed) — real-time but IEX-only volume (~2.5% of consolidated market volume). Fundamentals + earnings: Finnhub.

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
- Net profit margin is 530.4%. Finnhub fundamentals ↗
Potential concerns
- Revenue growth is -51.6% on the provider's reported measure. Finnhub fundamentals ↗
- Latest SEC filing is Form 8-K, filed 2026-07-22; 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.
