The More You Spend… — 2026-07-09
Core thesis: Memory chipmakers (MU, SK Hynix) are announcing massive capex plans because demand for chips vastly outstrips supply today—but investors are pricing in cyclical risk, knowing that timing mismatches between long demand cycles and long-term supply expansions can destroy returns.
Key points:
- MU announced $25B/10-year spending; SK Hynix announced $28B financing. Both rallied ~7%, signaling investor confidence demand will justify the investments.
- The "makers/takers" theme extends within semiconductors: MU becomes a "taker" of semiconductor equipment (ASML +5%, AMAT +7%, LRCX +7%).
- Semiconductor valuations (P/E ratios) remain modest even during scorching demand because investors have seen cycles before—supply eventually catches up, demand can peter out, or both.
- Current tight supply is driving price increases; capex is the natural response, but the risk is oversupply or demand collapse when new capacity comes online.
Takeaway: Today's rally reflects confidence in sustained AI-driven demand, but traders should monitor for signs of demand deceleration or supply-demand timing misalignment—classic cyclical semiconductor risks that historically compress multiples.
