ARM Drops 10% — But the Street Just Raised Its Targets

The positioning picture has changed materially since the June 22 report described shares short as "essentially flat" at 13.4% of free float. With percent-of-float data absent from this snapshot, the directional read comes from absolute shares: 19.14 million as of June 23, up roughly 3% on the week and about 20% above the mid-May base. Short sellers who built positions at mid-$200s prices and held through the run to $439 have now seen the stock give back roughly 17% from its high — partial relief, but nothing close to vindication. Borrow conditions remain loose. Cost to borrow is unchanged at under 0.50%, effectively free for a stock of this volatility. Availability has tightened sharply this week — from 264% to 216% — a meaningful move, though still comfortably in normal territory and far from the sub-50% level that signals genuine squeeze pressure. The ORTEX short score has climbed to 59.96, its highest reading in the 10-day window tracked here, rising steadily from 54 in mid-June. That drift upward reflects accumulating short-side signals even as the absolute squeeze threat remains modest.

Options traders have flipped to a noticeably less defensive stance, which is the sharpest divergence in the current setup. The put/call ratio dropped to 1.17 — almost two standard deviations below its 20-day average of 1.24, with a z-score of -2.20. After a month of elevated put demand that coincided with the stock's run toward all-time highs, options market participants are now buying relatively more calls into the dip. That's the opposite of what a pure momentum-chasing or panic-selling dynamic would produce. It suggests at least part of the market views Tuesday's decline as a buying opportunity rather than the start of a sustained reversal. Earnings are due July 29 — the last print added 2% the next day and 6% over five sessions; the March report delivered a 15% single-day move. With the stock now 17% off its high heading into that release, the options market's posture is worth watching.

Institutional ownership remains heavily skewed toward SoftBank's 86.4% stake, which continues to define the float dynamics for this name. Among active managers, Capital Research added 2.4 million shares through late May, Van Eck added 2.2 million, and Altimeter Capital initiated a fresh position of 1.7 million shares — all reported after the mid-May base was built. Insider activity through early June was uniformly sell-side: the Chief Accounting Officer sold $4.4 million worth of shares at $392, and the Chief Commercial Officer sold across multiple tranches in May and June. None of the trades carry high significance scores, and the context of a stock that doubled in a month makes structured selling unremarkable, but the absence of any insider buying into the rally is a data point worth noting.

The next focal point is the July 29 earnings release — and given that the stock closed this week at $366 with analyst targets clustering between $360 and $500, the question for that print is less whether ARM can grow and more whether the royalty revenue trajectory and early CPU revenue numbers justify a valuation that still prices in a P/E above 169x.
