Is Sterling Infrastructure Heavily Shorted?
"Days to cover" is the number of average trading days it would take shorts to buy back their position at recent volume. For STRL, that’s currently 2.19 days against 531,455 shares of average daily volume. A low days-to-cover means shorts can exit on normal volume, so short-squeeze risk is muted here.
STRL Short Interest in Context
Short interest is most useful read against the rest of the picture. Heavy shorting that lines up with insider selling and weakening Employee Business Outlook is a different story from heavy shorting with insider buying and a positive AI Score — the same number, very different setups.
The other signals on STRL right now:
- STRL AI Score — 74/100
- Reddit sentiment — 91/100 (bullish)
- Employee Business Outlook — 66% positive (positive)
Read together, this is a broadly constructive setup: short interest is contained and the underlying signals lean bullish. Limited room for a short-side surprise.

Sterling Infrastructure Short Interest: Frequently Asked Questions
Sterling Infrastructure has 1,161,560 shares short — about 3.80% of its shares outstanding as of Sep 30, 2026. This figure is the official biweekly short interest report, which lags the settlement date by about two weeks — the same convention every short-interest tracker uses. (Note: "% of shares outstanding" runs slightly below the "% of float" you may see on MarketBeat or Fintel, since float excludes insider-held and restricted shares.)
At 1,161,560 shares short and 531,455 shares of average daily volume, STRL’s days-to-cover is 2.19. A low days-to-cover means shorts can exit on normal volume, so short-squeeze risk is muted here.
Short squeezes happen when heavily shorted stocks rally sharply, forcing shorts to buy back at higher prices. The classic warning signs are days-to-cover above ~5, rising short interest, and a catalyst that pushes price up. STRL’s days-to-cover at 2.19 is below the classic ~5-day threshold. AltIndex tracks short interest alongside insider activity and sentiment — the same number reads very differently depending on what those other signals say.
The biweekly short interest figures come from NASDAQ’s official short interest report — the same source used by MarketBeat, Fintel, and Benzinga. The data is settlement-date-based, published twice a month, and lags about two weeks. For daily short-selling activity (a higher-frequency complement), see the short squeeze tracker.
