Which US stock has the highest days to cover?

Sinovac Biotech, Ltd. has the highest days-to-cover figure for settlement date 15 Sep 2026: 999.99 days, with 0.11% of its shares outstanding reported short, per FINRA's consolidated short interest report.

Is a high days-to-cover figure good or bad?

Neither. It is a ratio, and a high value can come from a large short position, thin trading, or both. It says nothing about why the position exists or where the share price will go, and it is not investment advice.

US stocks with the highest days to cover

FINRA's days to cover is reported short interest divided by the stock's average daily trading volume: the number of days of typical trading it would take for every short position to be bought back. For settlement date 15 Sep 2026, 3,805 ranked US stocks carry the figure and 505 of them sit at ten days or more. The figure is FINRA's own, published in the same report as the short counts; we never compute it, because that would need price and volume data we do not use. See days to cover, explained.

What does days to cover mean?: Days to cover is the reported short interest divided by the stock's average daily trading volume, as FINRA computes and publishes it: how many days of typical trading it would take for every short position to be bought back. It describes the size of the short position relative to how actively the stock trades, not how likely a squeeze is.
Is a high days-to-cover figure good or bad?: Neither. It is a ratio, and a high value can come from a large short position, thin trading, or both. It says nothing about why the position exists or where the share price will go, and it is not investment advice.
