KLA Corporation is now being sold by almost everyone who matters — executives cashing out near the highs while the stock continues to drift lower, with short interest nudging back up just enough to keep the debate alive.
The price has continued to erode since the previous notes. KLAC closed at $194.79 on August 18, down 5.3% on the day and off 8.4% over the past month. That puts the stock a further leg lower from the $203.72 close flagged in the August 16 report. The July 28 earnings print — a 16.3% single-session collapse — remains the defining event. The stock has not meaningfully recovered. Peers are confirming the sector-wide pressure: ONTO fell 10.2% on Tuesday and AMKR dropped 10.5%, while AMAT and shed between 4% and 5% on the day. This is not a KLAC-specific move — but KLAC's elevated short interest means the pain is being felt with added leverage.
Short interest has started to creep back up after its post-earnings unwind. Bearish positioning rose 6.1% on the week to 28.0 million shares, equivalent to 21.3% of the free float. That follows a sustained retreat from the early-July peak of roughly 37 million shares, so the overall trajectory remains lower. But the week-on-week tick higher is a new development — the first sustained weekly increase since the post-earnings cover trade began. The borrow market continues to offer zero read-across to conviction: availability is essentially unlimited at the platform's maximum reading, and cost to borrow has fallen 20% over the week to just 0.36%. Shorts adding back are doing so freely and cheaply, not under duress. The options market has moved in the opposite direction, with the put/call ratio easing to 1.54 — below its 20-day average of 1.61 and roughly 1.5 standard deviations lighter on protective demand than recent weeks. Hedgers are stepping back even as short sellers nudge forward.
The Street remains constructive but notably less so. The analyst response to July 28 earnings showed a clear pattern: most firms held ratings but cut targets sharply. Wells Fargo trimmed to $245 from $305, Susquehanna to $215 from $275, Stifel to $250 from $270, and Deutsche Bank to $195 from $220 — all on July 29, the morning after the print. JP Morgan moved against the grain, raising to $238 from $200 while keeping Overweight. The consensus remains a buy at 14 buys versus 9 holds, with no sells. But the mean target has compressed significantly, and at $194.79 the stock now trades below Deutsche Bank's $195 hold target and well below the group's central estimate. Bulls lean on KLAC's dominance in process control, deep TSMC and Samsung relationships, and management confidence in a 2027 growth acceleration. Bears counter that customer concentration, limited exposure to etch and deposition, and a premium valuation relative to peers justify remaining on the sidelines — particularly with no major process node catalyst before late 2026. The 90-day EPS momentum factor score of just 2 out of 100 captures how severely the estimate revision cycle has turned.
Insider selling remains the most consistent signal in the data. Since the August 12 note, EVP Brian Lorig added a $12.4 million sale (59,586 shares at $208.13) to the cluster already flagged. CEO Richard Wallace, CFO Bren Higgins, and CLO Mary Beth Wilkinson all sold in the August 7–12 window. The 90-day net insider value sold has reached $107 million. These are almost certainly pre-planned 10b5-1 trades, but the scale and simultaneity across the entire C-suite — CEO, CFO, General Counsel, divisional president, Chief Accounting Officer — is striking. Institutions tell a different story at the margin: Capital Research added 13 million shares through July 31, and FMR (Fidelity) added 23.7 million — both meaningful votes of longer-term confidence that sit in tension with the executive selling trend.
The next earnings event is scheduled for October 30. Between now and then, the debate centres on whether the $194 level holds as a base or whether the stock drifts further toward the Deutsche Bank target and below. The short interest rebuild — modest as it is — and the continued insider selling are the two signals worth tracking most closely into that print.
