Led by the tech-heavy Nasdaq Composite (.IXIC), Wall Street closed Tuesday higher, bouncing back from a sell-off set off last week by a Fed policy update that suggested officials believed rates would rise more quickly to counter rising inflation. The Nasdaq closed at another record high, as top-shelf tech companies resumed their growth trajectories.

"I really think there"s a realization that this is a ripe environment: rates are still low and for stock investors, this hits a "just right" tone," said Patrick Leary, chief market strategist at Incapital. "The market is concerned about rising inflation numbers and was getting more unnerved as the Fed dismissed them until last week’s meeting." Testifying before Congress, Powell vowed that the Fed will not raise rates out of fear of potential rising inflation, and instead will prioritize a "broad and inclusive" recovery of the job market. He said recent price increases do not suggest higher rates are needed, and instead can be attributed to categories directly impacted by economic reopening. read more "After the FOMC took the wind out of the reflation trade at the end of last week, that’s started to reverse over the last two days.
