KLA’s Phantom Plunge: Why a 6% Friday Rally Matters More Than an 88% Monthly Drop

The numbers on the tape tell one story — but the reality tells another. KLA Corporation’s stock appears to have cratered by 88% over the past month, a figure that would terrify any shareholder. That panic is an optical illusion. The culprit is a 1-for-10 stock split executed in mid-June, which recast the share price into smaller denominations. Strip away that technical adjustment, and the picture shifts dramatically.

On Friday, the stock surged 6.06%, closing at €218.00. The move snapped a sharp pullback: the shares had lost roughly 11% earlier in the week as investors took profits across the semiconductor equipment space. This sell-off, analysts stress, was a garden-variety sector rotation, not a company-specific blowup. Indeed, pure-play AI chip designers held their ground, suggesting the dip was nothing more than a breather after a prolonged rally.

Inside the Machine Room of the AI Super-Cycle

KLA sits at the crossroads of the semiconductor industry’s most powerful long-term trend. The company’s process-control systems are indispensable for manufacturing advanced logic and memory chips, particularly the high-bandwidth memory and accelerators that power AI data centers. The hunger for storage is especially acute: Samsung and SK Hynix have earmarked a combined $1.3 trillion for new fabrication capacity in South Korea, and KLA’s inspection tools are mandatory equipment for those fabs.

Industry forecasts peg global semiconductor revenue at roughly $1 trillion by 2026, and much of that growth will come from hyperscale data-centre buildouts. While the consumer electronics market has softened, the AI-driven investment cycle shows no signs of cooling. KLA’s order pipeline is a direct beneficiary of this wave, and the financial impact will be quantified when management reports fourth-quarter fiscal results at the end of July.

Should investors sell immediately? Or is it worth buying KLA-Tencor?

Chart Chaos and a Contrarian Signal

The stock split has scrambled the usual technical metrics. Annualised volatility has spiked to an extreme 283%, while the Relative Strength Index has sunk to 25.5 — territory that typically signals a deeply oversold condition. In plain English, the selling pressure appears statistically overdone.

Yet Wall Street remains cautious. The consensus price target stands at roughly €187, a notable discount to Friday’s close. That implies analysts see limited near-term upside, even as the company’s strategic position strengthens. The split-driven volatility has made valuation models harder to read, and many strategists are waiting for hard numbers before upgrading their views.

The Real Test Arrives in July

All eyes now turn to the fourth-quarter earnings release, due later this month. That report will provide the clearest gauge yet of how deeply the AI infrastructure boom is filling KLA’s coffers. Until then, the stock’s wild swings will likely persist — a split-induced statistical mirage that masks a quietly dominant franchise.
