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.

Peer and sector context

No reviewed peer group is available for this symbol.

Balanced evidence

A deterministic summary of sourced facts—not an AI verdict.

Potential strengths

  • Revenue growth is 10.9% on the provider's reported measure. Finnhub fundamentals ↗
  • Latest SEC filing is Form 10-Q, filed 2026-08-07; review it for current changes and risks. SEC EDGAR ↗

Potential concerns

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

Institutional holders

SEC Form 13F filers holding RPID as of the latest reported quarter. 13F only covers investment managers with $100M+ in assets — this is not a complete ownership picture, and does not include insiders (see Recent SEC filings below) or non-13F-eligible holders.

Institutional ownership is not available for this symbol right now.

Insider activity

Directors, officers, and 10%+ owners' reported transactions from SEC Form 4. A filing reports a transaction; it does not by itself explain why it happened.
