The market absorbed two primary macro events today: an interim US-Iran agreement to end military hostilities and reopen the Strait of HormuzNYTBloomberg, alongside the SpaceX $85.7 billion IPOFinancial Times.
This dual catalyst transferred directly to the cross-section. The Oil factor fell to z=-1.9, reversing a relatively flat multi-week trend. The decline tracked a drop in global crude prices as geopolitical risk premiums compressed, as NYT reported. The move concentrated in the highest-exposure names. Exploration and refining equities led the selloff, with XOM declining -4.0% and the broader energy sector falling -2.95%.
The Oil factor's sharp selloff among highest-exposure names today cuts against its relatively flat 63-day trend, reacting cleanly to the Strait of Hormuz de-escalation.

Conversely, the energy decline catalyzed a cyclical rotation. The Beta factor led the style complex at z=+1.9, extending a 63-day run (z_63d=+1.5). This move showed monotonic agreement across horizons, with cyclical components outperforming defensive names.
Beta's cross-horizon slope agreement confirms that today's cyclical outperformance is an acceleration of a deeply entrenched multi-week structural trend.

The capital absorption lifted large-cap technology equities. The Growth factor (z=+1.6) and Size factor (z=+1.4) advanced, raising the Information Technology sector by +2.09% on the median stock.
The semiconductor complex anchored these flows. MU rose +10.0%, WDC gained +16.0%, and AMD added +6.9%. The 10-Year Treasury yield declined 1.2 bps to 4.47%CNBC, and the US Dollar Index fell -0.06% to 99.68CNBC, accommodating the duration-sensitive advance.

Short Sale Factor Indicates Active Alpha Generation
As the Nasdaq gained over 3%, the Short Sale factor presented a distinct divergence. Printing at z=-1.9, the factor indicated that stocks heavily shorted the prior day underperformed the broader market. Instead of a mechanical short squeeze driving broad unwinds, active short sellers generated alpha. This dynamic—most-shorted names falling despite the index-level advance—showed capital flowing into AI and cyclical equities while selling fundamental underperformers. The 63-day trend reached an extreme z_63d=-4.0, confirming a persistent, multi-month regime of favorable conditions for active short-selling strategies.
KOSPI Reclaims 8,000 Ahead of MSCI Review
The cyclical advance extended to international equities, led by South Korea. The EWY ETF rose +6.76% on elevated volume, reflecting local gains as the KOSPI index reclaimed the 8,000-point levelBloomberg. The +59.04% 63-day return in EWY remained heavily tethered to the global semiconductor cycle, while expectations for the upcoming MSCI developed market classification review added localized momentum.
