Is Tilray Heavily Shorted?

"Days to cover" is the number of average trading days it would take shorts to buy back their position at recent volume.

Tilray Short Interest: Frequently Asked Questions

Tilray has 18,790,909 shares short — about 12.71% 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 18,790,909 shares short and 3,615,725 shares of average daily volume, TLRY’s days-to-cover is 5.20. Days to cover above 5 is elevated and worth watching — a sustained upside move could put visible pressure on the short side.

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. TLRY currently meets the days-to-cover 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.
