Analyst downgrades and cautious Wall Street calls. In July 2025, Goldman Sachs downgraded SK Hynix to "neutral" from "buy," warning that intensifying competition in high-bandwidth memory (HBM) could trigger the first price decline in that segment . By August 2026, Goldman had reversed course — reiterating buy ratings on Samsung and SK Hynix and calling the pessimism excessive — but the damage to sentiment had been done. July 2026 saw 828 analyst downgrades, double the number of upgrades, with most cuts targeting chip and tech stocks . Citigroup trimmed its Micron target in March 2026 citing softening DRAM spot prices , and Jefferies also joined the cautious chorus, though specific Jefferies downgrade notes from this period were not independently confirmed in the search results.

Doubts about AI capital spending. A persistent worry that the massive AI infrastructure buildout may not deliver proportional returns has hammered the sector repeatedly. Broadcom's weak guidance in early June , the Nasdaq entering correction territory in late July , and repeated spillovers from U.S. semiconductor routs into Asia all amplified these fears .

Weak Wall Street sessions cascading into Asia. Every major down day in U.S. tech stocks — including the July 28 Nasdaq correction and the July 17 selloff that hit Nvidia hardest — was immediately transmitted to Asian markets. South Korean and Japanese chip stocks track U.S. overnight moves closely .

Mixed earnings and guidance from key names. SK Hynix posted record quarterly profit but still missed analyst estimates, sending shares down more than 10% in a single session . SanDisk and Western Digital were routed alongside other memory names in late July , and SanDisk's pre-market drop of over 10% on August 6 underscored persistent earnings pressure . AppLovin-specific guidance details were not surfaced in the search results but the broader pattern of disappointing AI/monetization outlooks added to the uncertainty.

Valuation fear and leverage unwinding. By early August, Samsung and SK Hynix had fallen 23% and 35% respectively over the prior month . Short-term rallies — like the 27–30% surge on August 1 in Samsung and SK Hynix — were swiftly reversed as investors unwound leverage-backed positions .
