Wall Street indexes are wavering amid another slew of results from some of the biggest U.S. companies. Here’s what we’re watching ahead of Wednesday’s action:

• Coca-Cola reported third-quarter profit and revenue that rose above expectations and raised its full-year earnings growth view.
• McDonald’s reported third-quarter earnings and sales that beat expectations.
• Robinhood Markets shares dropped in early trading. Fees tied to stock and options trades ticked down slightly at the popular app, while revenue tied to cryptocurrency trading tumbled 78% to $51 million.

• Microsoft ‘s earnings report showed that the software giant continued to benefit from the global shift toward remote work as its cloud business boosted its revenue last quarter.
• DWAC , the blank-check company that is taking former President Donald Trump‘s social-media venture public, opened higher then quickly reversed track to shed more than 5%.
• Enphase Energy shares soared more than 20%. KeyBanc lifted its price target for the stock after the solar technology company reported higher revenue during the recent quarter.
• Google parent Alphabet was nudging higher after the search giant posted its highest quarterly revenue increase in 14 years, as smaller businesses pour money into digital ads.
• Twitter largely dodged turmoil in the digital advertising market from new Apple app privacy policies and supply-chain disruptions as it reported a 37% jump in third-quarter revenue.
• Visa beat earnings expectations amid higher payments volume, cross-border volume and processed transactions.
• F5 Networks reported after Tuesday’s close that revenue had grown 11% during its fiscal year.
• Boeing reported a quarterly loss as 787 Dreamliner production problems and its latest space-launch setback offset a recovery in demand for new aircraft.
• Ford and  eBay  are among the companies reporting earnings after Wednesday’s close.

Chart of the Day
