KLA Short Sellers Hold a Fifth of the Float Before Tuesday's Print

KLA Corporation enters its October 28 earnings release with short sellers holding 17.8% of the free float, a level that has barely budged despite a sharp drawdown in the stock itself.

Short interest has fallen about 2.7% over the past week and is down 21% over the past month, but at 23.4 million shares it remains one of the heavier bearish positions in the semiconductor equipment space. The month-long reduction mirrors the stock's move lower: KLAC fell 20.6% in October, touching $149.21 at Monday's close, down 10.3% for the week. That is modestly worse than the peer group median, with AMAT off 7.8% and MKSI down 8.5% over the same five sessions, though LRCX fared worse at -12.8%.

Borrow costs have jumped sharply, tripling over the past month to 1.21%, after spending most of September and early October below 0.5%. Despite that move, availability remains loose: 1.3 billion shares are available to borrow against the 23 million currently lent, so there is no squeeze pressure in the lending market. The cost spike looks more like episodic demand around the print than any structural tightening.

Options positioning is nearly neutral. The put/call ratio of 1.30 is almost exactly in line with its 20-day average of 1.29, a z-score of just 0.21, meaning traders have not paid up materially for downside protection into the event. That contrast with the elevated short interest is the central tension in the setup: bears have taken a large structural position but have not added to it aggressively in the final approach, and options markets show no sign of panic.

The debate among analysts reflects genuine disagreement about the cycle. Bulls point to KLA's structural moat in process control, a $140 billion-plus wafer fabrication equipment forecast for 2026, and management guidance of $15 billion-plus in calendar-year revenue, alongside growing services income and improving 2027 visibility in memory and leading-edge demand. Bears focus on valuation, with the stock historically expensive relative to its five-year average, and on China exposure exceeding 30% of revenue, where export controls and domestic competition remain live risks. Morgan Stanley trimmed its target to $227 from $253 in early October while keeping an Overweight rating, a move that captures the consensus direction: the Street broadly remains constructive but has been marking down price targets since July. The mean analyst target of $232 implies more than 55% upside from current levels, an unusually wide gap that itself reflects how far the stock has fallen from where the Street expected it to trade.

Retail attention has picked up ahead of the print. Wikipedia traffic for KLA is running 1.7 standard deviations above its own 90-day history, a signal of elevated retail interest rather than any revenue indicator.

Tuesday's print will test whether the quarter's actual numbers close the distance between a $149 stock and a Street that still has targets clustered between $180 and $325.
