Bears Pile Into Energy and AI Plays

Short interest data from ORTEX as of 30 October shows several sharp moves in the past week. The action is concentrated in energy infrastructure, AI hardware, and restructured names.

TLN, Talen Energy, saw its short interest jump 5.2 percentage points in seven days to 10.7% of free float. The power producer's stock has gained heavily on data-centre demand narratives. Bears are now pushing back.

CBRS, Cerebras Systems, tells a similar story. The AI chip maker's SI % FF rose 4.6 points to 19.8%. Shares in the Nasdaq-listed firm have doubled in recent months. Availability sits at 113%, so new short positions are still easy to build.

WOLF remains under severe pressure. Short interest at Wolfspeed stands at 86.5% of free float. Zero availability means shorts are trapped. The cost to borrow is just 2.2%, unusual for such an extreme SI reading.

HTZ keeps its unenviable position. Hertz carries 73.4% SI % FF and a cost to borrow of 162%. Zero shares available to borrow signal the trade is maxed out.

On the cover side, SVRA saw the biggest retreat. Savara short interest dropped 11.3 points to 25.6% of free float in a week. IBTA, Ibotta, shed 7.8 points.

EVCM holds the highest ORTEX short score in the dataset at 97. Its SI % FF sits at 15%, cost to borrow is 74%, and availability is under 1%.

The ORTEX Index Rebalance Radar flags MRNA as 88% likely to re-enter MSCI World. Forced buying could reach $5.9 billion, which may accelerate short covering in the name.
