The Troops Are Leaving Before the Generals

A short-term top in second-tier semis is likely in place — not the end of the bull, an early-warning shot.

Two semiconductor ETFs are telling two different stories today, and the gap between them is the signal.

SMH — the cap-weighted complex, carried by the mega-cap names — is still climbing: +5.46% over five days, green on the day. XSD — the equal-weight S&P semiconductor index, where the smaller and second-tier chip names actually carry weight — has rolled over: −0.46% on five days and −1.94% in the last session, last 601.16 into a negative divergence off the April-low high. In a watchlist of twenty-plus tech ETFs, XSD is the only name printing red over five days.

That is not noise. That is breadth. When the equal-weight version of a sector turns down while the cap-weighted version keeps rising, the move is being carried by fewer and fewer names. The generals are holding the line; the troops have already started to retreat.

Why XSD is the cleaner gauge here

SMH is a mega-cap fund — NVIDIA and Broadcom carry it. XSD is the inverse by construction: a modified equal-weight basket of roughly 43 names. The numbers make the point better than any chart can.

So XSD doesn't measure “semis.” It measures the second tier — and the second tier has stopped going up.

XSD — top weights (the second tier that drives it):

And look at what's actually driving XSD. The heavy weights are the high-beta speculatives: Astera Labs (4.09%), Navitas (3.62%), Credo (3.03%), SiTime (3.01%), Rigetti (2.24%), Ambarella, Wolfspeed. This is exactly the cohort that runs hardest in the everyone-up phase — and breaks first when leadership narrows. When this basket turns red while NVDA-heavy SMH is green, you are watching the marginal buyer leave the riskiest end of the trade.
