Prices are daily closes from Polygon.io. Company figures come from its own SEC filings. Past moves are not a forecast. OQRO reports what was filed and never tells you what to buy or sell.
Short sale volume: 53.1% of the volume reported to FINRA over the last 20 trading days was marked short, close to its 1-year average of 53.2%. FINRA daily files, to Oct 2, 2026.
Fails to deliver: 4,240 shares (about $4.9M) were not delivered on time for settlement on Sep 2, 2026. SEC fails-to-deliver data.
Short sale volume is not short interest. It counts trades marked short, including market makers selling short to fill buy orders, so it is a share of daily trading, not a count of bets against the stock. Fails to deliver have many causes, including processing delays, and are often resolved within days.
Last 12 months, adjusted daily closes
