"The essence of investment management is the management of risks, not the management of returns." - Benjamin Graham
Read the Short-Interest Data Fast
- Start at the Short-Interest page and sort by the largest absolute percentage changes.
- Open the symbol view to compare trend direction, price action, and recent liquidity conditions.
- If the table appears stale, refresh your short-interest and quote snapshots before decision-making.
Interpret the Signal with Context
- Rising short interest while price falls can indicate distribution and weaker conviction.
- Rising short interest with flat price can signal crowding; confirm with catalyst timing and borrow costs.
- Falling short interest with rising price can indicate covering pressure and improving sentiment.
"You are neither right nor wrong because the crowd disagrees with you." - Benjamin Graham
Action Framework
- Increase with volume surge: verify borrow availability and thesis quality before adding exposure.
- Increase without volume support: treat it as unconfirmed; wait for repeated signals.
- Decrease with price strength: identify whether it is a temporary squeeze or a true thesis rerate.
- Tiny float names: use smaller size because small borrow shifts can cause large price moves.
Pair with Other Site Signals
- Cross-check Share-Changes; higher shorts plus new issuance is usually negative.
- Confirm with Interesting-Volume; short-interest spikes are stronger when turnover is elevated.
- Review Near-Lows to decide whether the setup is capitulation recovery or ongoing impairment.
Process discipline
- Log each decision with date, short percent of float, liquidity, and thesis status.
- Refresh around earnings, financing announcements, and major filing updates.
- Keep explicit exit rules if both price and short-interest trends move against the thesis.

Frequently Asked Questions
-
What counts as a meaningful short-interest jump?
Material day-over-day changes should be evaluated with float size, dollar volume, and borrow conditions.
-
Does high short interest make a net-net attractive?
Not by itself. You still need valuation support, catalyst probability, and manageable balance-sheet risk.
-
How often should I check?
Daily for active names and event-driven setups; weekly can work for less active microcaps.
