Index funds carry AXT's 425% run; Beijing gates the order book

Passive money owns the register

BlackRock reported 9,359,639 shares of AXT on October 5, 14.3% of the company as of September 30, in a Schedule 13G/A↗ that certifies the stock was not acquired to influence control ¹. Inside that number sits iShares Core S&P Small-Cap ETF, alone above 5% of AXT, more than a third of BlackRock's stake ¹. That is index plumbing, not a view on indium phosphide. It is what S&P's September 21 addition of AXT to the SmallCap 600 does to a register: trackers must buy, and the stock rose as much as 16.4% that day ².

Fast money stacked on top

The trading around the stock matches the run. Tradr announced a 2X short AXTI daily ETF on August 13 for sophisticated traders; the stock has swung from $3.70 to $143.16 in a year ³. Retail is calling for $95 ⁴. Hedge funds fell to 33 holders from 37, while the survivors lifted committed capital 34% to $487.9 million ². After a 425.2% rise this year ⁸, the buyer still accumulating at scale is the index machine.

The cash customers actually paid

The demand story does hold dollars. In the second quarter AXT received prepayments of $22.3 million and $25.4 million from Coherent and Casela; in July Lumentum signed a six-year capacity reservation↗, $43.5 million due within 30 business days and a second $43.5 million whose terms settle in 2028, terms The Inference traced on October 1↗ ⁵⁶⁷. InP backlog runs well over $100 million into 2027 ⁵. But each deposit posts as a liability and becomes revenue only when wafers ship ⁵.

One permit from revenue

All of AXT's substrates are grown at three plants in China, and every shipment leaving the country needs a Ministry of Commerce license, under controls in force since February 4, 2025↗, and never suspended ⁶⁷. In a August 13 filing AXT called permits its most significant challenge and said it could not estimate when U.S. approvals would arrive, after a January outlook cut followed a permit shortfall ⁶. The $66 million third-quarter guide counts only revenue already permitted or exempt, and China, over half of second-quarter sales, needs no permit at all ⁵. The deposits are dollars; the revenue is paperwork.

Who pays at 14 times sales

At 14.19x forward sales against a 5.25x industry average, a Value Score of F and a Hold rank ⁸, the stock is a re-rating standing on one record quarter after three flat years.

October 29 is the first real test

The bull case is real: gross margin went from 8% to 44.9% in a year, the InP capacity doubling runs ahead of schedule, and consensus sees 146.4% revenue growth in 2026 ⁵⁸. What the multiple adds is the assumption that permits keep arriving, which management says it cannot predict ⁵. AXT itself sold $632 million of stock on April 22 and ended June with $748.8 million of cash ⁵. The next reading lands after the close on October 29↗: revenue against the $66 million already permitted, and the first conversion of customer deposits into shipped wafers ¹⁰.
