Momentum Unwinds to Fund Tech Short Squeeze

China Equities Fall and Oil Prices Decline

Macro factors are overriding equity beta in global markets. The China factor is notably negative at z=-2.32, weighing on ADRs.

The policy mandates a two-year liquidation period for unauthorized accounts, pushing the KraneShares CSI China Internet ETF (KWEB) down -15.26% over the trailing 63 days.

The energy sector also declined. Oil prices fell following reports of a tentative U.S.-Iran ceasefire extension aimed at restoring shipping traffic in the Strait of HormuzBloomberg. The United States Oil Fund (USO) fell -2.73% on the day.
