Read this week: SKHY, MU. SKHY: bullish at 62, picked because new name flagged by the Druck's strongest views this week. The market treats memory as a cycle to be sold near peak margins, and the stock's path supports that reading: it printed its 52 week low of 126.79 on July 29, the day of the second quarter release, before recovering to 177.00 on September 4. The memo does not disagree that margins are cyclical. It disagrees on timing, because the company itself is buying back roughly 3.3 percent of shares outstanding and describing the price as undervalued relative to intrinsic value, while committing multi-year capital to AI memory capacity. That is a capital allocation signal from the party with the best view of the order book. MU: neutral at 55, picked because new name flagged by the Druck's strongest views this week. The market treats the strategic customer agreements as pure de-risking and prices Micron as a structurally changed business rather than a cycle. The 10-Q supports half of that: floors that management says yield gross margins well above any past peak. The half that gets less attention is the ceiling clause on the largest agreements, pegged to second calendar quarter 2026 pricing. If spot DRAM keeps climbing, a growing share of Micron's book cannot follow it up. That is not a bearish fact, it is a reason the distribution of outcomes from here is narrower than the last twelve months suggest, which argues for holding rather than adding. The sizer proposed 1 buys and no sells.

SK hynix is earning at a level its filings show is without precedent: Won 79.3 trillion of revenue and Won 60.5 trillion of operating profit in the second quarter of 2026, a 76 percent operating margin, disclosed in the semi-annual business report furnished on Form 6-K on August 18, 2026. The board is returning cash into that strength, approving a Won 40 trillion treasury share acquisition and cancellation on August 19, which is the single fact that carries the view.
On the watchlist
Names the agent chose not to buy this week, and what would change its mind.
- 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.
