Nasdaq ended last week up ~5%, its strongest in months, as the tech comeback took shape (Amazon and Palantir earnings, chip strength); Alphabet and Tesla report this week with ~85% of S&P names beating estimates so far. QQQ recovered from its 661 low to 723, reclaiming the upper end of its range. Earnings catalysts plus momentum favor UP over the week; the elevated ~32x forward P/E is the main downside risk.
