CoreWeave Short Sellers See 30% of Profits Lost on Borrow Costs

Short sellers targeting cloud computing provider CoreWeave Inc. have accrued an estimated $700 million in paper profits as the company's shares fell approximately 31% from their June record high. However, nearly 30% of these gains are expected to be offset by significant stock borrowing costs, highlighting the substantial expense and inherent risks associated with shorting one of the market's most expensive stocks to borrow.

Analysis

Short sellers targeting CoreWeave Inc. have capitalized on a significant price correction, with the cloud computing provider's shares falling 31% from their June record high, generating approximately $700 million in mark-to-market profits. However, the profitability of this trade is severely constrained by exceptionally high stock borrowing costs, which are poised to consume nearly one-third of these gains, according to data from S3 Partners LLC. This dynamic underscores CoreWeave's status as one of the most expensive equities to short globally, presenting a formidable hurdle for bearish investors. The prohibitive cost to borrow, even amidst a successful directional bet, highlights a significant technical factor that can pressure short sellers to cover positions, thereby creating a potential source of buying demand independent of the company's fundamental performance.

Key Decisions for Investors

• Potential short sellers must meticulously calculate the impact of high borrowing fees, as these costs have proven to significantly erode profits even when the short thesis proves correct.
• Investors should recognize that the punitive cost of shorting may act as a technical support for the share price, as it could compel bears to buy back shares to close their positions.
• Monitoring changes in stock borrow rates and short interest levels for CoreWeave is critical, as any significant decrease could signal a shift in conviction among bearish investors and alter the supply-demand dynamic for its shares.
