$SOXX will rebalance quarterly.
Its top 5 positions have capped weight at 8% and the remaining will be capped at 4%.
During the quarter, if some stocks run too hot, it could have a larger weight than the cap.
This will create excessive selling as companies like Marvell has heavy weight in $SOXX now but needs to be at 4%.
The rebalance will take effect on Jun 18, 2026.
Other companies like $MU will also need to be sold to reduce weight.
