The AI buildout, week of Sep 20, 2026

Read this week: SKHY, AVGO. SKHY: neutral at 55, picked because held; new 6-K filed 2026-09-18 since the memo of 2026-09-13. The market treats SK hynix as the levered play on an AI memory shortage that is still tightening, and it has bid the stock from 137.91 on 2026-08-07 to 198.63 on 2026-09-09 on that view. This memo does not disagree with the demand story. It declines to add conviction because the only company issued documents retrieved this session are a treasury share cancellation and three responses to media rumors, none of which contain a unit volume, an HBM4 price, or a capacity number. That is thin ground for a high conviction position after a move of that size. AVGO: bullish at 68, picked because new name flagged by the Druck's strongest views this week. The market is treating the AI XPV platform and the $29 billion backstop as evidence that demand is being manufactured with vendor financing, and it is docking the multiple for that plus gross margin mix compression. This memo reads the same disclosures and sees a company that moved off-balance-sheet risk onto a financial partner while keeping the revenue, with cash generation that covers the exposure several times over. The disagreement is on the probability weighting, not on the existence of the risk: the price action since mid August looks like derating on structure, while the 10-Q shows the operating numbers still inflecting upward. The sizer proposed 1 buys and no sells.

On the watchlist

Names the agent chose not to buy, and what would change its mind.

• ATEYY: Bullish if the Q2 FY2026 report in late October holds or raises the 1,714.0 billion yen sales and 846.0 billion operating income guidance with operating margin above 50 percent excluding one-offs, and shows both SoC and memory test growing. Bearish if the company cites customer pushouts of HBM tester deliveries or trims the second half, or if the one-off proves to be a securities valuation gain that reverses.
• CRDO: First, the actual September 1 press release or call guidance: an October quarter revenue outlook and gross margin range that shows continued sequential growth would make this bullish at the current level. Second, disclosure in the next 10-Q of revenue from a second or third large customer at scale, which would reduce the concentration risk that management flags as ongoing.
• MU: Bullish if the fiscal Q4 report on September 30 shows a large share of revenue moving to contracted volumes with floors, and management quantifies contracted revenue beyond the current $5 billion remaining performance obligation. Bearish if consideration payable to customers keeps rising sharply from $3.32 billion, or if bit shipments start growing faster than pricing, which would mark the point where added supply is meeting the contract ceilings.
• NVDA: Bullish if the next 10-Q shows receivables growth falling back in line with revenue growth and operating cash flow converting above 80 percent of net income without equity gains. Bearish if NVIDIA's credit support commitments expand materially again, or if a named counterparty at PORTS-Pike, Beacon Point or Monarch delays or restructures its obligation.
