Performance Overview (Trailing returns vs S&P 500 benchmark)
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.

Institutional holders
SEC Form 13F filers holding GSTX 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.
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.

Insider purchases & sales, last 6 months
Counts only open-market purchases (code P) and sales (code S) — grants, option exercises, tax withholding, and gifts are excluded since they aren't a market buy/sell decision.
