Why Is KLA Corporation (KLAC) Stock Down -5.27% Today?
Key Takeaways
- KLA Corporation shares fell 5.27% in Thursday trading, extending yesterday's 11.77% plunge, as a brutal semiconductor selloff gripped Wall Street for a second consecutive session.
- The two-day rout has erased roughly 16.4% from the stock's value since Tuesday's all-time closing high of $301.71, with shares last trading at $252.15.
- Primary catalysts include mounting valuation concerns after a parabolic year-to-date run, fears that Meta Platforms may recalibrate its AI infrastructure spending, and broad-based profit-taking across the chip equipment space.
- Sector peers including Micron Technology, SanDisk, Applied Materials, and Lam Research also suffered steep declines, confirming the move is driven by industry-wide repositioning rather than company-specific news.
- Traders are now watching for the upcoming June jobs report, next earnings season, and any commentary from major chipmakers that could stabilize or further rattle the semiconductor equipment complex.
Opening Summary
KLAC, the stock of KLA Corporation — the dominant provider of process control and yield management solutions for the semiconductor industry — tumbled 5.27% in Thursday's trading session, deepening a rout that began yesterday. Shares last changed hands at $252.15, down from Wednesday's close of $266.19. The decline compounds Wednesday's 11.77% collapse from $301.71, marking one of the most severe two-day selloffs for the semiconductor equipment giant since the early-2020s cycle. The move reflects a powerful convergence of valuation anxiety, sector rotation, and emerging questions about the pace of AI-driven capital expenditure growth that had propelled KLAC to a 52-week high of $307.37 just days ago.
Semiconductor Selloff Enters Second Day as Valuation Fears Compound
The semiconductor equipment sector is experiencing its most intense bout of selling pressure in months, with KLAC at the epicenter. After rallying more than 116% year-to-date and nearly 200% over the trailing twelve months, the stock had reached valuation levels that left little room for error. At its peak, KLAC traded at a trailing price-to-earnings ratio above 75 and a forward P/E near 51 — multiples far exceeding the company's five-year historical median of approximately 26. When a stock is priced for perfection, even modest shifts in sentiment can trigger outsized moves, and that dynamic is playing out in real time.
The selloff is not isolated to KLAC. MU (Micron Technology) dropped more than 10% on Wednesday and continued sliding Thursday. SNDK (SanDisk) fell over 10%, while AMAT (Applied Materials) and LRCX (Lam Research) each declined sharply. The VanEck Semiconductor ETF (SMH) suffered significant losses, confirming that the pressure is sector-wide rather than stock-specific. The Nasdaq-100 also softened, with the broader tech complex underperforming the Dow Jones Industrial Average, which managed to hold above the 52,000 level.
Meta's AI Spending Pivot Fears Ripple Through the Chip Ecosystem
A fresh catalyst rattling the semiconductor space is growing concern that Meta Platforms may be recalibrating its artificial intelligence infrastructure spending strategy. Reports and analyst commentary suggesting that hyperscaler capital expenditure patterns could shift have injected uncertainty into a sector that had been riding a wave of seemingly limitless AI-driven demand forecasts. For KLAC, whose process control tools are indispensable to leading-edge logic and high-bandwidth memory manufacturing, any perceived slowdown in the pace of AI capacity buildout directly threatens the growth narrative that had propelled shares to record levels.
This anxiety is layered on top of earlier concerns about memory chip demand. In late June, reports that SK Hynix might moderate its high-bandwidth memory production ramp to protect conventional DRAM margins had already triggered a 9% single-day drop in KLAC. While the stock recovered sharply — surging nearly 12% on June 30 after Cantor Fitzgerald raised its price target to $325 — the whiplash underscored how sensitive the name has become to any hint of a demand inflection.
Profit-Taking After a Historic Run
The magnitude of KLAC's rally entering July made it a prime candidate for profit-taking. The stock had gained over 35% in the month of June alone, and its 10-for-1 stock split earlier in the month had broadened retail accessibility while also attracting a surge of short interest. When the selling began on July 1, forced covering by late-arriving longs and algorithmic deleveraging amplified the downside, creating a self-reinforcing cascade. Thursday's continuation suggests that institutional investors are using the liquidity to reduce exposure ahead of the holiday-shortened week and a critical June employment report.
Adding a modest headwind, CEO Richard Wallace sold approximately $10 million worth of shares in mid-June at an average price of $221.34, according to SEC filings. While insider selling is not uncommon after a stock split and a massive run-up, it does little to reassure jittery retail and institutional holders during a selloff.
Market Context and Trading Activity
Trading volume in KLAC was elevated for a second straight day, with Thursday's activity running well above the 10-day average. The stock sliced through its 20-day moving average and was testing key technical support levels that had held during prior pullbacks. The semiconductor equipment sector as a whole traded with a risk-off tone, underperforming the broader S&P 500 and Nasdaq Composite. The selloff coincided with a modest bid in defensive sectors and a decline in Treasury yields, suggesting a classic rotation out of high-beta momentum names.
Despite the brutal two-day move, it is worth noting that KLAC remains up more than 100% year-to-date, and the fundamental backdrop — including Moody's decision on July 1 to affirm the company's A2 credit rating and shift its outlook to positive — has not deteriorated. The rating agency cited expectations for mid-to-upper-teens annual revenue growth driven by AI-related semiconductor investment, a view shared by most Wall Street analysts covering the name.

What Comes Next for KLAC
The immediate focus for KLAC traders will be the June nonfarm payrolls report, released Thursday morning, which could shape macro sentiment heading into the holiday weekend. Beyond that, the company's fiscal fourth-quarter earnings report, expected around July 30, looms as the next major catalyst. Management had guided for approximately $3.575 billion in revenue, and investors will scrutinize not only the top-line print but also free cash flow conversion, which has shown signs of compression in recent quarters despite strong earnings beats.
Analyst sentiment remains broadly constructive, with 20 buy ratings and 10 hold ratings among the 30 firms covering the stock, and a consensus price target that has been rising. However, the wide gap between the Street-high target of $325 from Cantor Fitzgerald and the consensus mean near $277 highlights the uncertainty around valuation. Key risks include potential escalation of U.S.-China export controls — China contributed roughly $4 billion of KLA's fiscal 2025 revenue — and any further signals that hyperscaler AI capital expenditure growth may be decelerating. For now, the stock is in the hands of a market that is rapidly repricing the premium it had assigned to AI-driven semiconductor equipment demand.
