US sector ETFs rally Monday; global airlines ETF up 5.15%, semiconductors 5.05%

The dispersion here is the story: airlines and semiconductors, two of the most cyclical corners of the market, outpaced defensives and energy by a wide margin, while energy's slim gain stood apart from the broad risk-on tone. That pattern points to a rotation toward growth- and travel-sensitive exposure rather than a uniform bid across sectors. Whether this leadership holds, or energy's lag proves the more telling signal, is the open question worth watching.
