$BDX (Becton Dickinson) has a Float Lock of 3.69% — the raw short interest number most trackers stop at. Float lock alone doesn't tell you how fast that position could need to unwind, or how tight the available shares to borrow are getting. That's what SIA's Coverage Velocity, Saturation Index, and Liquidity Constraint metrics are built to catch.
Unlike headline short interest figures sourced from periodic regulatory filings (which can lag by weeks), SIA Terminal's core metrics are recalculated the moment you look a ticker up. None of this predicts a price move or a timeline; it reflects the mechanical pressure in the underlying short position as of right now.
Float Lock is just the raw number. Unlock Coverage Velocity, the Saturation Index, and Liquidity Constraint for $BDX — and every S&P 500 / Nasdaq 100 ticker.
