The firm tracks a basket of stocks that score 70 or higher on its 0-100 squeeze scale, meaning conditions are ripe for shorts to get forced out of their positions. Twenty-four names currently qualify for that basket, and the cohort has climbed 13.4% month-to-date, pressuring short sellers across the board. - _PLTR stock is moving._ See the real-time price action here.  ## **Palantir’s Outlier Position** Short interest in Palantir now totals $12 billion. That’s the largest dollar short in the basket and well above its $3.37 billion average. The stock is also the group’s biggest gainer, up 41.4% month-to-date. It carries the largest mark-to-market loss for shorts at $5 billion.  **Read Also: Moderna's Cancer Vaccine Win Is Merck's Story Too** Benzinga’s short-interest tracker shows bets against Palantir have generally kept growing even as the stock climbs, adding to those unrealized losses. Yet the position covers just 3% of float, leaving the stock with the lowest crowded score in the basket at 32.5.  Few short sellers are involved, but those involved picked the wrong side. ## **Mark-To-Market Losses Mount** Recent mark-to-market losses across the basket total roughly $15 billion, and close to two-thirds of that sits in just three names. Palantir accounts for $5 billion, followed by **Lumentum Holdings Inc.** (NASDAQ:LITE) at $3.1 billion and **Super Micro Computer Inc.** (NASDAQ:SMCI) at $1.3 billion.  All three are also the basket’s biggest movers, each up more than 34%. ## **The Squeeze Score**  S3 Partners builds its squeeze score on top of a separate crowded score, which grades how tightly packed a short position is using short-dollar size, stock loan liquidity, trading volume and short interest. The squeeze score then layers on rising stock-borrow costs and mark-to-market losses, since those factors typically force short sellers to cover. Palantir’s pain fits a broader pattern across the basket, where the average squeeze score now sits at 80.8.  **Fox Corp.** (NASDAQ:FOXA), **Workday Inc.** (NASDAQ:WDAY) and Super Micro all hit the maximum reading of 100.  **Leon Gross**, S3 Partners’ director of research, summed up the dynamic: a rising market acts like the tide, lifting all boats — and every squeeze score with them. ## **The Most Crowded Shorts** **Charter Communications Inc.** (NASDAQ:CHTR) and Fox carry the heaviest crowding scores, at 85 and 80, followed by **EchoStar Corp.** (NASDAQ:ECHO) and **Skyworks Solutions Inc.** (NASDAQ:SWKS) at 77.5 each, against a 62.0 average.  Benzinga’s tracking shows Charter Communications’ short interest at 50.40% of its float, the heaviest in the basket. **Read Also: Michael Burry Says This AI Chip Startup Is 'Serious Competition' for Nvidia** _Photo: Shutterstock_ ### Related Stocks - [PLTR.US](https://longbridge.com/en/quote/PLTR.US.md) - [PLTD.US](https://longbridge.com/en/quote/PLTD.US.md) - [PLTW.US](https://longbridge.com/en/quote/PLTW.US.md) - [PLTZ.US](https://longbridge.com/en/quote/PLTZ.US.md) - [PTIR.US](https://longbridge.com/en/quote/PTIR.US.md) - [PLTG.US](https://longbridge.com/en/quote/PLTG.US.md) - [PLOO.US](https://longbridge.com/en/quote/PLOO.US.md) - [PLTU.US](https://longbridge.com/en/quote/PLTU.US.md) - [PLT.US](https://longbridge.com/en/quote/PLT.US.md) - [PLTA.US](https://longbridge.com/en/quote/PLTA.US.md) - [PLTY.US](https://longbridge.com/en/quote/PLTY.US.md) - [PLYY.US](https://longbridge.com/en/quote/PLYY.US.md) - [MRNA.US](https://longbridge.com/en/quote/MRNA.US.md) - [MRK.US](https://longbridge.com/en/quote/MRK.US.md) - [LITE.US](https://longbridge.com/en/quote/LITE.US.md) - [SMCI.US](https://longbridge.com/en/quote/SMCI.US.md) - [FOXA.US](https://longbridge.com/en/quote/FOXA.US.md) - [WDAY.US](https://longbridge.com/en/quote/WDAY.US.md) - [CHTR.US](https://longbridge.com/en/quote/CHTR.US.md) - [ECHO.US](https://longbridge.com/en/quote/ECHO.US.md) - [SWKS.US](https://longbridge.com/en/quote/SWKS.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [FOX.US](https://longbridge.com/en/quote/FOX.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) ## Related News & Research - [Gallagher Capital Advisors LLC Has $1.41 Million Stock Holdings in Palantir Technologies Inc. $PLTR](https://longbridge.com/en/news/296319209.md) - [Plancorp LLC Sells 3,071 Shares of Palantir Technologies Inc. $PLTR](https://longbridge.com/en/news/295912281.md) - [Palantir director Alexander D.
