(Reuters) -Wall Street’s main indexes climbed on Monday as investors braced for earnings from megacap growth and technology companies, while focusing on an interest rate decision from the Federal Reserve.

All eyes will be on the quarterly reports of Microsoft (NASDAQ:), Google-owner Alphabet (NASDAQ:) and Meta Platforms this week, as market participants will be keen to know whether their earnings justify sky-high valuations.

The action-packed week also includes the Fed’s policy meeting, with the central bank expected to raise interest rates by 25 basis points on Wednesday.

A majority of economists polled by Reuters expect this to be the last increase of the current tightening cycle, after data this month showed signs of disinflation.

“It’s a pretty important week for investors who may be a little cautious because of the earnings and also about what the Fed will say,” said Chris Zaccarelli, chief investment officer for Independent Advisor Alliance.

Helping the Dow notch its longest winning streak in over six years, Chevron (NYSE:) gained 3.2% as the oil giant posted upbeat preliminary quarterly earnings over the weekend.

Ten of the 11 major S&P 500 sectors were higher, led by a 2.1% gain in energy stocks.

Toymaker Mattel (NASDAQ:) rose 1.9% as the “Barbie” movie set a record as the biggest domestic debut of 2023.

AMC Entertainment (NYSE:) jumped 31.6% after a judge blocked the theater chain’s stock conversion plan that risked diluting investors’ holdings in the company. AMC’s preferred shares fell 2.2%.

Exchange operator Nasdaq trimmed the weight of a handful of companies that make up close to half of the to address “overconcentration” in the benchmark.
