Lam Research enters the second week of May with one of the sharpest recoveries in the semiconductor equipment space — and the short book tells a big part of that story.
The stock gained 10% on the week to close at $275.80, adding 27% over the past month. That recovery did not happen in a vacuum. Short interest topped out in mid-April at around 29.8 million shares, roughly 2.4% of the float. It has since dropped by more than 12% to 26.1 million shares — about 2.1% of the float. That's a meaningful cover, not noise. Shorts who built into the tariff-uncertainty sell-off have largely exited. The borrow market reflects it too: availability remains wide and cost to borrow has been cheap throughout, ending the week at just 0.39%. The ORTEX short score is a modest 31.8 out of 100 — well below levels associated with real squeeze pressure — and the short-score trend has been flat to marginally rising since late April, suggesting remaining short interest is stable rather than emboldened.
Options positioning has nudged slightly more defensive as the stock has ripped higher. The put/call ratio moved up to 1.09 this week, about 1.5 standard deviations above its 20-day average of 1.04. That's notable but not alarming — the 52-week high on the PCR sits at 1.37, so there's room. The most natural read is that some holders are buying puts to protect recent gains into what remains a murky macro environment for semis, rather than any directional short bet against the name. The options setup looks like hedging rather than conviction.
The Street is firmly in the bull camp. After Lam's April 22 earnings print — which delivered only a hair of a 1-day move despite expectations for volatility — analysts queued up to raise targets. JP Morgan lifted to $315, Citigroup to $315, RBC Capital to $310, Wells Fargo to $320, Stifel to $325, and TD Cowen to $340. Seaport Global initiated with a Buy and a $300 target just this week. The consensus sits at Buy with a mean price target of $310, implying about 12% further upside from current levels. Only Barclays holds out at Equal-Weight, with a $275 target that now sits right at the current price — a neutral read rather than a bearish one. The bull case rests on Lam's dominant position in etch and chemical vapour deposition equipment, with memory-focused customers like SK Hynix, Samsung, and Micron set to drive a new spending cycle. Bears point to constrained clean-room capacity, NAND weakness, and export restriction risk as near-term headwinds.
Valuation has re-rated meaningfully with the price. The P/E has expanded to 42.8x, up more than four points over the past month, and price-to-book now at 25.5x has added 3.5 points in the same period. The EV/EBITDA at 35.2x is actually down marginally on a 30-day basis, which suggests earnings estimates have been revised upward alongside the price — consistent with the wave of post-earnings target upgrades. The RSI sits at 63, not yet at overbought levels, which gives the technical picture a relatively clean look despite the move.
On the ownership side, BlackRock added 10 million shares in the most recently reported period and now holds 10.7% of the company — the largest single institutional position. T. Rowe Price added 10.7 million shares, a significant build. FMR (Fidelity) added 3.7 million. The pattern suggests that large active managers used the April dip to increase exposure, not reduce it. Insiders, by contrast, have been consistent sellers: the CFO Doug Bettinger sold approximately $29.4 million of stock in late February and early March, and a Senior VP sold another $4.6 million in early May. The 90-day net insider figure is a net sale of roughly $99.5 million in value. That level of selling from the CFO is worth noting, though it likely reflects planned selling arrangements rather than a sudden change of view given the stock had been significantly lower at the time.
The next earnings event is scheduled for July 30. With the stock now back near multi-month highs and the analyst community having broadly updated targets post-April results, the next print will be about whether the memory recovery is sustaining and whether export restrictions are biting harder than the company's April guidance implied. Peer AMAT gained 7.8% on the week and KLAC slipped 4.2%, a divergence worth watching as a read on which parts of the equipment complex investors are most comfortable owning into the summer.
