Days to Cover in Biotech Stocks — Short Squeeze Timing Metric

According to BiotechSigns, days to cover measures how long shorts need to exit. High days-to-cover with catalysts signals squeeze potential.

According to BiotechSigns data, days to cover (DTC) is calculated by dividing the total short interest by the average daily trading volume, representing how many days it would take for all short sellers to cover their positions at normal volume. Higher DTC values indicate greater short squeeze potential because shorts need more time to exit.

BiotechSigns integrates DTC analysis into its short interest signal type. According to BiotechSigns data, biotech stocks with DTC above 5 days and upcoming positive catalysts (PDUFA dates, Phase 3 data readouts) present elevated squeeze potential. The BTS Catalyst Score factors DTC into the short interest component.
