NEW YORK, July 28 ― The Nasdaq jumped more than 4 per cent yesterday in its biggest daily percentage gain since April 2020 as the Federal Reserve raised interest rates as expected and comments by Fed Chairman Jerome Powell eased some investor worries about the pace of rate hikes.

Quarterly reports from Microsoft Corp, Alphabet Inc and others added to the day's upbeat tone.

The S&P 500 growth index jumped 3.9 per cent and also registered its biggest one-day percentage gain since April 2020. Tech and growth stocks, whose valuations rely more heavily on future cash flows, have been among the hardest hit this year.

The S&P 500 closed at its highest level since June 8, with the technology sector giving the index its biggest boost.

The Fed, in a statement following its two-day meeting, raised the benchmark overnight interest rate by three-quarters of a percentage point. The move came on top of a 75 basis points hike last month and smaller moves in May and March, in an effort by the Fed to cool inflation.

Powell's comments in a news conference after the statement gave some investors hope for a slower pace of rate hikes.

Equity investors have been worried that aggressive hikes by the Fed could tip the economy into recession.

“He did not commit to any specific rate hike in the September meeting,” said Jim Paulsen, chief investment strategist at The Leuthold Group in Minneapolis.

Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia, said it was “a calming statement, coming on the heels of a day where you saw some earnings and revenues that were better than expectations, albeit expectations that were very tempered.”

The Dow Jones Industrial Average rose 436.05 points, or 1.37 per cent, to 32,197.59, the S&P 500 gained 102.56 points, or 2.62 per cent, to 4,023.61 and the Nasdaq Composite added 469.85 points, or 4.06 per cent, to 12,032.42.

Yesterday's hike was widely anticipated by investors.

Microsoft rose 6.7 per cent after it forecast double-digit growth in revenue this fiscal year on demand for cloud computing services.

Alphabet jumped 7.7 per cent, a day after it reported better-than-expected sales of Google search ads, easing worries about a slowing ad market.

T-Mobile US Inc added 5.2 per cent after it raised its subscriber growth forecast for the second time this year and exceeded quarterly profit expectations.

Volume on US exchanges was 10.56 billion shares, compared with the 10.88 billion average for the full session over the last 20 trading days.

Advancing issues outnumbered declining ones on the NYSE by a 5.27-to-1 ratio; on Nasdaq, a 3.15-to-1 ratio favoured advancers.

The S&P 500 posted one new 52-week high and 30 new lows; the Nasdaq Composite recorded 50 new highs and 107 new lows. ― Reuters
