NEW YORK CITY, RAW – Tepid results from Tesla and 3M have weighed on Wall Street, with the main indexes ending mixed as investors focus on a wave of earnings reports from Microsoft, Alphabet and other corporate heavyweights.

Electric-car maker Tesla Inc dropped after its quarterly results late on Monday fell short of some investors’ expectations, with its revenue beat largely supported by sales of environmental credits and selling bitcoin rather than vehicle sales.

Microsoft Corp and Alphabet Inc were in choppy trade ahead of their quarterly reports after the bell.

Shares of Apple Inc, Facebook Inc and Inc, slated to report later this week, were mixed for much of the session.

“Everyone is waiting to see the big tech earnings after bell today. If it’s good, I think I think we’ll have a lot of positive momentum. If they’re disappointing, we may be in for a very volatile week,” said Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa, Oklahoma.

Shares of 3M Co fell after the conglomerate said supply chain disruptions from the COVID-19 pandemic and the February winter storm were pushing up its costs.

First-quarter overall earnings per share for S&P 500 companies are expected to jump 35 per cent from a year earlier, which would be the biggest surge since the fourth quarter of 2010, according to Refinitiv IBES data.

The S&P 500 and the Nasdaq ended at record levels on Monday, recently supported by improving economic data, a swift vaccine distribution and unprecedented monetary and fiscal measures.

“We are in that spot where the economy is recovering, there is stimulus money to be spent and people have increased their desire and propensity to consume. For the remainder of the year, you’re going to see some fairly optimistic thoughts,” said Tom Martin, senior portfolio manager at Globalt Investments in Atlanta.

Investors will monitor the Federal Reserve’s two-day meeting for cues on the central bank’s thinking on inflation, bond buying and risks to the financial system posed by soaring asset prices.

The Fed is not expected to change its policy guidance at the end of the meeting on Wednesday.

In the latest upbeat economic data, US consumer confidence jumped to a 14-month high in April as more services businesses reopened on increased vaccinations and additional fiscal stimulus.

The Dow Jones Industrial Average rose 1.25 points, or 0 per cent, to 33,982.82, the S&P 500 lost 1.05 points, or 0.03 per cent, to 4,186.57 and the Nasdaq Composite dropped 48.56 points, or 0.34 per cent, to 14,090.22.

Also expected to report after the bell on Tuesday were companies including Visa, Texas Instruments, Amgen and Starbucks.

United Parcel Service Inc jumped after it topped estimates for quarterly revenue.

General Electric fell after it disappointed investors who were expecting the industrial conglomerate to upgrade its 2021 outlook.
