Short squeezes look random from the outside. A stock sitting at $3 for weeks suddenly gaps to $12 in two days. Retail traders pile in after the move. Institutions who were positioned before it print massive gains.
The truth: most squeezes do not come out of nowhere. There are measurable signals in the borrow market — the infrastructure that shorts rely on — that show the setup building days or weeks before the price move. Here are the five signals the VisionBoard Squeeze Scanner tracks.
1. Short Interest Percentage (SI%)
Short interest is the percentage of a stock's float that has been sold short. A 10% SI is normal. A 30% SI is elevated. A 50%+ SI on a small float is a loaded gun.
Why it matters: every short position eventually has to be covered by buying the stock back. The higher the SI%, the more forced buying is waiting to happen. On a micro-float stock with 50% SI, that forced buying can overwhelm normal sell-side liquidity entirely.
What to look for: SI above 20% on floats under 20M shares. The smaller the float and the higher the SI, the more violent the potential squeeze.
2. Borrow Rate
To short a stock, you have to borrow shares from a broker or institution. The borrow rate is what you pay annually for that loan. Easy-to-borrow stocks cost 0.3-1%. Heavily shorted, hard-to-find stocks can cost 50%, 100%, even 200%+ annually.
A high borrow rate creates a financial clock on every short position. At 100% borrow, a short holding for 6 months has paid 50% of the stock price just in carry costs — before any move against them. This forces weaker shorts to cover, which drives the price higher, which forces more shorts to cover. That is the squeeze.
What to look for: borrow rates above 20% are elevated. Above 50% is extreme. Above 100% means shorts are under severe financial pressure to exit.
3. Borrow Rate Acceleration
A high borrow rate is notable. A borrow rate that is suddenly rising fast is the real signal. When borrow jumps 50%, 100%, or 200% in a week, it means demand to short the stock is outpacing the supply of shares available to lend. The lenders are raising their price because the product is scarce.
This is the early warning signal — often appearing days before the squeeze itself. The VisionBoard scanner flags stocks where borrow rate has risen more than 50% in 7 days as a priority alert.
4. Shares Available to Borrow
Every broker has a pool of shares available to lend to short sellers. When that pool shrinks to zero, new shorts cannot enter the position. Existing shorts who need to roll their borrow cannot do so. Forced covering begins.
What to look for: watch for availability that is cratering fast — down 50%, 70%, 90% in a week — and especially stocks where availability has already hit zero. Zero availability is the tripwire. Once it is crossed, the only direction for the squeeze pressure is up.
5. RegSHO Threshold List
When a stock has persistent failures-to-deliver (FTDs) — meaning shorts sold shares they could not actually locate to borrow — it ends up on the SEC's RegSHO threshold list. This is a public signal that the short side of this stock has a settlement problem.
RegSHO stocks are required to close out their FTD positions within a specific window. This creates forced buying that is entirely independent of price action or catalysts. It is mechanical demand.
Any stock on RegSHO with high SI, high borrow, and disappearing availability is the highest-risk setup for a squeeze.
How the VisionBoard Scanner Combines All Five
The VisionBoard Squeeze Scanner scores every stock across all five signals, weights them by conviction, and produces a ranked list daily. A stock scoring 60+ is an active alert. A stock on RegSHO with zero availability and borrow above 50% is a critical setup.
The scanner does not predict which stocks will squeeze — nothing can do that with certainty. What it does is surface the stocks where the structural conditions for a squeeze are in place. The setup is identifiable. The timing is not.
