All three main U.S. indexes ended last week higher and appear set to gain this month as signs of cooling inflation and a resilient economy have cemented investor bets on a soft landing for the country. Upbeat quarterly earnings from megacap growth companies including Alphabet GOOGL.O, Meta Platforms META.O as well as chipmakers Intel INTC.O and Lam Research LRCX.O have also boosted investor sentiment. Blue-chip index Dow .DJI this month logged its longest winning streak in nearly four-decades underpinned by gains in sectors including healthcare, financials and energy that had underperformed during the first half of the year.
