OAKLAND, RAW – The S&P 500 ended higher on Thursday, with Microsoft and Tesla fuelling a late-session rally while investors eyed the war in Ukraine and a potentially more aggressive Federal Reserve.

Gains in Microsoft Corp, Tesla Inc and Apple Inc helped lift the S&P 500.

Also supporting the S&P 500, Pfizer Inc jumped after it said it would buy privately held ReViral Ltd in a deal worth as much as $525 million, its second acquisition in less than six months to boost its drug portfolio.

The S&P traded at a loss for much of the day before rallying near the end of the session.

“We don’t know how Ukraine is going resolve itself. We don’t know how this hawkish Fed is going to impact the economy. We don’t know if they can navigate a soft landing. What it equals is a whipsaw market,” said Dennis Dick, a trader at Bright Trading LLC. “If you’re following trends, then you’re lost in this market because all this market is is chop.”

Mega-cap growth stocks came under pressure earlier this week after comments from Fed policymakers and minutes from the central bank’s March meeting suggested a rapid removal of stimulus measures put in place during the pandemic.

St. Louis Federal Reserve President James Bullard said the US central bank’s short-term policy rate should reach 3.5 per cent later this year.

Minutes released on Wednesday showed that Fed officials “generally agreed” to cut up to $95 billion a month from the central bank’s asset holdings even as the war in Ukraine tempered the first US interest rate increase since 2018.

“The realisation for investors continues that the Fed is still not at max hawkishness and we’re going to err on the side of them wanting to do more to continue to control inflation,” said Anastasia Amoroso, chief investment strategist at iCapital Network, an investment marketplace firm.

Traders now see 88.9 per cent likelihood of a 50 basis-point rate hike at the central bank’s meeting next month.

US companies will start reporting first-quarter results in the coming weeks, with banks set to kick off the season in earnest next week. Analysts on average expect S&P 500 companies’ earnings to have grown 6.4 per cent in the March quarter, according to I/B/E/S data from Refinitiv. That compares with over 30 per cent growth in the prior quarter.

“As we get into the heart of earnings season, I expect volatility to be very prominent,” said Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa, Oklahoma. “We could see strong results that beat the highest expectations, but weak expectations for the next 12 months.”

Among the 11 S&P 500 sector indexes, real estate was among the deepest decliners, while the health sector index was among the top gainers.

Adding to cautious sentiment, Russian Foreign Minister Sergei Lavrov said Ukraine had presented Moscow with a draft peace deal that contained “unacceptable” elements, while the US Senate voted to remove “most favoured nation” trade status for Russia in one bill and ban oil imports in another.

According to preliminary data, the S&P 500 gained 17.83 points, or 0.40 per cent, to end at 4,498.98 points, while the Nasdaq Composite gained 5.78 points, or 0.04 per cent, to 13,894.60. The Dow Jones Industrial Average rose 93.50 points, or 0.27 per cent, to 34,590.01.

With investors worried about the effect of rising interest rates, growth stocks with pricey valuations have underperformed value stocks so far in 2022.

In economic news, data showed the number of Americans filing new claims for unemployment benefits fell last week, indicating a further tightening of labour market conditions heading into the second quarter that could contribute to keeping inflation elevated.
