Axcelis Technologies heads into its May 6 earnings release with short sellers at their most cautious in six weeks — just as options traders edge into their most defensive posture of the past month.
Short sellers have been paring back aggressively. The SI % FF fell from a high of 13.3% in mid-March to 11.3% now — a drop of roughly 10% on the week alone and nearly 14% over the past month. That's the lowest reading in the 30-day window. The ORTEX short score has also been unwinding steadily, sliding from 63.2 on April 21 to 59.8 by April 28, signalling that the aggregate bearish signal is losing conviction heading into the print.
The lending market tells a consistent story. Availability remains well-supplied — borrowing costs are running at just 0.49% annualised, barely moved over a month, and the borrow pool is far from stressed. The overall availability picture suggests no squeeze pressure is building behind the short-covering. Where options diverge slightly is at the margin: the put/call ratio ticked up to 0.34, more than two standard deviations above its 20-day average of 0.31. The PCR is still low on an absolute basis — well below the 52-week high of 1.08 — but the relative move is the highest in roughly a month. Some participants are paying incrementally more for downside protection even as short sellers trim.
The Street is skeptical but not bearish. The consensus rating sits at hold, with two buys and two holds on the name. The mean price target is around $112 — well below the current price of $134, which is the widest gap the analyst data shows in the available history. That dislocation between where analysts have their targets and where the stock is trading is the most important Street tension right now. B of A holds an Underperform with a $100 target; B. Riley is neutral at $91. The stock has rallied 38% in a month, and analyst coverage has simply not kept up with the move. On factor scores, the analyst recommendation divergence score ranks in the 89th percentile — a formal signal that the stock is running ahead of what the sell-side thinks it's worth. The EV/EBITDA multiple has eased slightly over the past week to 29x but expanded materially over 30 days alongside the price rip. Valuation gives the bears something to work with.
The ownership picture shows some notable cross-currents. Victory Capital added 835,000 shares as of April 1 — a significant addition representing nearly 6% of shares outstanding. BlackRock and Vanguard hold steady as the two largest passive holders. On the insider side, the CEO, CFO, and several executive vice presidents all sold shares in a coordinated cluster on March 2 at prices near $87. The CEO has continued selling in March and April. None of these are large transactions in absolute terms — the largest single lot is under $500,000 — but the consistency of sell activity through a period when the stock has risen more than 40% from those prices is a pattern worth tracking.
Earnings history adds further texture. When Axcelis last reported in February 2026, the stock fell 13% on the day and nearly the same amount over the following week. That prior reaction — the worst in the recent history — came despite revenue and EPS beating estimates, driven by a sharp 46% drop in orders and a backlog decline that unnerved the market. That bear case, centred on order momentum rather than current-quarter execution, remains the central debate heading into May 6.
What to watch: whether the order trend and backlog figures released on May 6 show stabilisation or further erosion — that delta will likely determine whether short sellers who have been covering decide the exit was too early.
