"Today's Market Movers: Coinbase, Roku, and More"

Dow Jones futures edged lower while S&P 500 futures and Nasdaq futures rose modestly. Coinbase, Roku, DraftKings, Applied Materials, and Trade Desk were among the big earnings movers overnight. The stock market rally overcame weakness in megacap techs, but with bullish sentiment high and the indexes slightly extended, investors should be cautious about new buys. Various psychological indicators show bullishness at elevated levels, on the verge of being extreme. The Nasdaq is close to being extended, and many leading stocks are greatly stretched, indicating a need for caution.
