I reviewed all the week's closing prices on Saturday. Semiconductors dropped 7% on Friday, but only dropped less than 1% for the week. NVDA dropped 4.2% in one day, only 3% for the week. It wiped out a week's losses in one day. Money was being moved to lower levels all week. Pharmaceuticals rose 3.1% for the week. Telecoms dropped 5.3%. The S&P closed at 7580 on Friday, down 1.82% in one day. The index looks unchanged on paper, but the underlying market has changed drastically. I'll reduce my holdings if the S&P falls to 7450 next week.
