S&P 500 restores 5-year uptrend by breaking above the upper 1st standard deviation from 5-year mean (at 2020), signaling more long term upside probability.
One should also note that the August selloff did not trigger the test of the 10-year trend (price did not tag the 10-year uptrend border at 1845), meaning the upward bias is pretty strong on the index.
