Short Ratio

What is Days to Cover?

The number of days it would take short sellers to cover their positions based on average daily volume.

Think of it like this

Like measuring how many days it would take to empty a pool using a garden hose - more days means more shorts stuck.

Formula

Short Ratio = Shares Short รท Average Daily Volume
  • Shares Short: Total shares currently sold short
  • Average Daily Volume: Typical daily trading volume

Why it matters

  • Shows potential for short squeeze
  • Higher ratio = more squeeze potential
  • Indicates strength of bearish bets
  • Affects stock volatility
