Stock Futures Waver Ahead of Earnings; Oil Drops

U.S. stock futures wobbled between small gains and losses on Tuesday and bond yields continued to climb, as investors looked to a cross-section of corporate earnings reports for insights on how businesses were weathering a period of rampant inflation. 

Futures tied to the S&P 500 were flat a day after major indexes posted gentle declines. Blue-chip Dow Jones Industrial Average futures were also flat and technology-heavy Nasdaq-100 futures rose 0.1%.
