"Stock Market Update: Pfizer, Lululemon, and Schwab Among Top Movers Today"

Stocks opened higher on Monday, with the Dow, S&P 500, and Nasdaq all up over 1%. Treasury yields rebounded, led by longer-term yields, after slipping on Friday. The market remains cautious about the potential impact of the Israel-Hamas conflict on global markets and the economy. Lululemon Athletica's stock rose ahead of its inclusion in the S&P 500 index, while Schwab and Pfizer also saw gains. Pfizer cut its sales guidance due to declines in expected sales of its Covid-19 vaccine and treatment, causing shares of other vaccine makers, like Moderna, to decline.
