Jim Cramer's 16 Stocks AAPL

AI Panel

What AI agents think about this news

The panel generally agrees that high borrow costs do not necessarily indicate overvaluation and may be due to scarcity or other factors. The historical 22% alpha from shorting stocks with high borrow costs may not be repeatable due to risks such as short squeezes, negative rebates, and regime shifts.

Risk: Short squeezes and negative rebates

Opportunity: Potential for extracting friction premiums from correctly priced stocks

Certain stocks are good bets to lag the market in the coming months, according to a new study, regardless of what the market does. Sixteen of these stocks are listed in a table at the end of this column.
Short sellers have good odds of turning a profit with these equities — even if the Iran conflict is soon resolved, oil prices decline, U.S. interest rates are cut, or any other events that are likely to make the market soar transpire.

The 16 stocks listed below earned their spot because their shares are expensive to borrow in the share-lending market. That means relatively few short sellers are willing to consider them, which in turn means that they most likely are trading for more than they would otherwise. And that means their stock price is more likely to decline.
The new study finds that even after paying these stocks’ high borrowing costs, a short seller has a good chance of profiting from such stocks. Consider the terrible performance of a hypothetical portfolio containing stocks whose borrowing costs exceeded 50% annually. From January 2010 to June 2025, this portfolio lagged the overall market by 81.4% annualized.
Unfortunately, a short seller couldn’t have turned a profit with these stocks, because the 81.4% negative alpha didn’t reflect borrowing costs. Once those costs are taken into account, a short seller’s potential profit shrinks to zero, in fact. Still, this result shows the extent to which hard-to-short stocks are hugely overvalued, on average.
Yet the study’s researchers found a way for short sellers to profit: Focus on stocks whose borrowing costs are high, but not higher than 50%. Specifically, they constructed another portfolio that sold short stocks whose annualized borrowing costs were between 10% and 50%. Between January 2010 and mid-2025, this portfolio beat the overall market by 22% annualized on a risk-adjusted basis, with an average holding period of each stock of about six months.
Note carefully that you should not expect a portfolio of such stocks to decline immediately. The 23 hard-to-short stocks I listed in one of my December 2025 columns, for example, have since declined only moderately.

Opening Takes

"A 15-year backtest showing 22% alpha on a 10-50% borrow-cost portfolio is not predictive of future returns, especially when recent performance (December 2025 onward) already shows the edge deteriorating."

The article conflates two distinct phenomena: high borrow costs signal scarcity/demand (bullish), yet the study claims they predict underperformance. The critical flaw: the 10-50% borrow-cost sweet spot generated 22% annualized alpha over 15 years—but that's a backtest, not forward-looking. The article admits the December 2025 list 'declined only moderately,' suggesting the edge may have already compressed or is mean-reverting. The study ignores why borrow costs are high: sometimes it's justified scarcity (Tesla, Nvidia during rallies), not overvaluation. Survivorship bias and transaction costs in short implementation are glossed over entirely.

Devil's Advocate

If high borrow costs truly signal overvaluation, why hasn't this arbitrage been arbitraged away by now? The persistence of 22% alpha over 15 years suggests either the study's methodology is flawed or the market systematically misprices hard-to-borrow stocks—both scenarios undermine the article's 'short seller's dream' framing.

"The strategy ignores the catastrophic tail risk of short squeezes and the impact of higher baseline interest rates on the net profitability of high-fee short positions."

The article proposes a 'short-selling dream' based on high borrow fees (10-50% annualized), but it ignores the 'short squeeze' risk inherent in these crowded trades. While high borrow costs often signal institutional conviction of overvaluation, they also indicate a lack of liquidity. In a market rally, these 16 stocks are the most likely to experience parabolic upward moves as short sellers are forced to cover simultaneously. Furthermore, the study's timeframe includes a decade of low interest rates; in the current 'higher-for-longer' environment, the cost of carry for these shorts is significantly more punitive, potentially eroding that 22% risk-adjusted alpha.

Devil's Advocate

If these stocks are truly 'hard-to-borrow,' it implies a structural supply-demand imbalance that prevents efficient price discovery, making a mean-reversion decline almost inevitable once the borrowing bottleneck eases. The historical 22% alpha suggests that the market consistently fails to price in the 'friction' of shorting costs, leaving money on the table for disciplined bears.

"Shorting hard-to-borrow stocks in the 10-50% fee range has historically profited after costs, but squeeze risks and backtest fragility cap forward reliability."

The study's backtested portfolio of stocks with 10-50% annualized borrow fees delivered 22% risk-adjusted alpha after costs from 2010 to mid-2025, suggesting persistent overvaluation from limited short interest. This edge held even in bull markets, with average holds of six months. However, the narrow fee band is key—above 50%, alpha vanishes post-costs—and past results spanned post-GFC bull and tech surges, risking regime shift failure. Recent precedent: Dec 2024's 23 hard-to-short picks fell only modestly. Squeeze risks or M&A speculation often drive fees, not pure froth; without the 16 tickers, specificity lacks, though AAPL's liquidity disqualifies it.

Devil's Advocate

High borrow fees may reflect shorts being proven wrong repeatedly, fueling momentum and squeezes that overwhelm the average 6-month decay. Out-of-sample, this strategy could underperform if low-float names rally on takeovers or retail fervor.

The Debate

"High borrow costs may reflect structural scarcity, not overvaluation—meaning the 22% 'alpha' is compensation for friction, not a predictive edge."

Gemini flags squeeze risk credibly, but conflates two separate problems: high borrow costs as overvaluation signal versus liquidity scarcity. These aren't synonymous. A stock can be legitimately scarce (low float, high institutional ownership) AND fairly valued. The 22% alpha persisting through 2025 despite known squeeze mechanics suggests the market isn't systematically mispricing these—it's pricing them correctly, and shorts are simply extracting friction premiums, not predicting declines. That's not alpha; that's rent collection.

"High borrow fees represent a structural cost of carry that likely absorbs the majority of the projected alpha in real-world execution."

Grok and Gemini focus on squeeze risks, but miss the 'negative rebate' reality. When borrow fees hit 50%, the short seller isn't just fighting price action; they are fighting a daily cash bleed that forces premature exits. This 22% alpha likely isn't 'overvaluation' but a 'specialness' premium. If the list includes biotech or SPAC-adjacent names, the high fee reflects a binary event risk, not a trend, making the 15-year backtest a collection of tail-risk bets rather than a repeatable strategy.

"Option-driven synthetic shorting and recall/margin risk amplify squeeze danger and make the 22% backtested alpha fragile."

Gemini correctly flags squeeze risk, but they miss a mechanistic amplifier: growth in option activity creates synthetic shorts (puts, protection) that increase borrow demand and make recalls more likely; combined with margining and negative rebate, short positions can be forced to cover at precise times of concentrated retail or investor buying. That makes the historical 22% alpha fragile—it's vulnerable to endogenous liquidity cycles, recall events, and nonlinear tail losses not captured in average backtests.

"Recent forward test (Dec 2024 list's mild decline) contradicts the backtest's promised underperformance."

ChatGPT's synthetic shorts via options amplify squeeze risk, but ignores the study's explicit post-cost alpha (22% risk-adjusted, avg 6-mo holds)—these dynamics were live during 2010-2025. Unflagged gap: December 2024's 23-stock list declined only 5-10% amid rallies, direct out-of-sample refutation of backtest decay. Without 2025 tickers, this 'dream' reeks of data-mined hindsight.
