U.S. stocks are holding onto cautious early gains ahead of Fed Chairman Jerome Powell confirmation heading on Capitol Hill later this morning.

U.S. equity futures nudged higher Tuesday, following on from the strongest late-session rally for tech stocks in nearly two years, as investors continue to grapple with inflation concerns that are compounded by a worrying surge in global Covid infections.

The Nasdaq rallied hard late Monday, after falling into so-called correction territory, a level defined as a 10% slide from a recent peak, during the trough of yesterday’s session. The tech-focused benchmark finished modestly higher, however, thanks to a near 3% single-day turnaround, the strongest rally since March of 2020.

Similar gains may be difficult to sustain Tuesday, with Federal Reserve Chairman Jerome Powell set to appear before the Senate Banking Committee later this morning and December inflation data looming Wednesday, but the turnaround has nonetheless steadied nerves on Wall Street heading into the start of the third quarter earnings season later this week.

In prepared remarks for his confirmation hearing testimony on Capitol Hill, set to begin at 10:00 am Eastern time, Powell said the country’s post-pandemic recovery will be “different in some respects”, but vowed to “prevent higher inflation from becoming entrenched” in the world’s largest economy.

Omicron’s relentless wave, however, continues to sweep across the country, with daily infections hitting a record 1.35 million yesterday, lifting the seven-day average to around 700,000 — a level last seen in January of 2021 — raising concerns that growth will be difficult to maintain in the face of business closures, travel restrictions and self-isolations.
