Nvidia Corp. faces the final test of an earnings season-driven rally that has sent its shares up about 45% from an April low.The world’s most valuable chipmaker reports Wednesday after market close — the last of the Big Tech cohort to do so.

If you look at historical guidance and compare it to actual revenue, it should be a good yardstick for estimating how things could turn out. Nvidia is guiding for Q1 $43 billion (plus/minus 2%). Wall Street expects $43.38 billion, with EPS near $0.87. Expectations are sky-high because the company has been beating estimates massively.
