ShortAtlas methodology
Days to Cover explained
Days to cover compares Short Interest with average daily volume. Learn how to interpret it and why it is only a reference metric.
The basic idea
Days to cover estimates how many trading days it could take for reported short positions to be covered if they were compared with average daily trading volume.
It is usually calculated from current Short Interest divided by average daily volume. The exact input definitions can vary by data source.
How to read a higher value
A higher days-to-cover value can suggest that open short positions are large relative to recent volume. It can also reflect low liquidity or a temporary change in trading activity.
The number should be read with the settlement date, volume period, and symbol type. It is not a prediction that covering will happen soon.
Limitations
Days to cover uses historical or reported inputs. It does not know future trading volume, future short covering, or intraday liquidity.
ShortAtlas shows days to cover as a neutral reference metric, not as a squeeze score, bearish score, or trading recommendation.
A worked example
If a stock reports 20 million shares of Short Interest and averages 5 million shares of daily volume, days to cover is 4. If average daily volume falls to 2 million while Short Interest stays flat, the same position balance now reads as 10 days.
Nothing about the short positions changed in that second case. Only the denominator moved, which is why the metric should be read alongside the volume period it was calculated from.
