OIH is trading 4.68% lower at $375.15 amid a retreat in U.S. stocks; no clear OIH-specific catalyst surfaced. - The S&P 500 is down 1.11%, and the Nasdaq is down 1.90%. - Strait of Hormuz tensions pushed Brent crude higher, while broader risk-off sentiment weighed on equities. This backdrop may be contributing, but the evidence does not establish a direct cause for OIH’s move. - OIH tracks oil-services companies, so rising crude alone does not explain the decline.
