I think the stimulus was so strong that it is still carrying. We printed 4 trillion dollars (20% of our GDP) for not 20% of our economy shutting down for the whole year. And that doesn't include other soft things that were done. And to make it political: Can you imagine where we would be if we had a president who promoted the scientists and didn't sow confusion about COVID?
That is an apt anaology. I think just when the economy would really start faltering after "stimulus" wears thin, the actual economy will begin getting a strong foothold. Stock market GDP forecasts for next 3 quarters seem to follow same playbook. If you ar elooking for buy and hold stock investments there are still plenty of undervalued stocks that if you can wait a year or more will yield 30-40% returns.
