PeakBullishMemory Supercycle

As AI demand surges, memory supply shortages persist, and this memory boom represents a structural supercycle rather than a temporary cycle, as proven by Samsung Electronics and SK Hynix's strong Q2 earnings.

Maintained top position in reports and news throughout the 7-day window. Monday (08-03) through Tuesday (08-04), statements like 'unchanged memory boom' and 'reassessment of long-term supply contracts' confirmed earnings and led to consensus formation. However, skepticism about 'peak-out' and circular finance began to attach, indicating consensus at its peak.

View analysis

Why it matters

Top consensus dominating the entire 7-day period. Multiple brokerages including Kyobo, DS, and Hana repeated 'sustained boom' in their 2Q reviews. Both reports and news were strong.

What would change it

Memory boom has already peaked due to concerns of semiconductor peak-out and accelerating CXMT localization.

ContestedBullishKOSPI Plunge/Deleveraging and Rebound

KOSPI experienced extreme selling due to the first-ever consecutive circuit breakers triggered by single-stock leveraged ETFs, but entered a rebound phase with leverage regulation as a favorable catalyst and Morgan Stanley's 'increased Korea weighting (target 9,000P)'.

Narrative of circuit breaker→selling→rebound expectations repeated within 7-day window. On Tuesday (08-04), a further 5.12% plunge occurred, attaching skepticism to 'imminent rebound' logic. Coexistence of Morgan Stanley weighting increase versus difficulty of August strength.

View analysis

Why it matters

New catalysts emerged: leverage ETF regulation and KOSDAQ spillover benefits. Morgan Stanley's target 9,000P spread to mainstream news. Both reports and news were strong.

What would change it
