Semiconductor gains will now have to come from earnings growth rather than multiple expansion, but NVIDIA at 19x forward earnings can still make money. Rising margins normally compress multiples because peak margins signal peak cycle; this cycle ran long and euphoric buying drove multiples up, so a correction was bound to happen. With capex growth projected to slow from 2028, semis growth will likely slow too, and the window to profit from buying chip stocks at 25x sales is closed. x.com
