A single stat that suggests this isn’t a bear market rally

The S&P 500 on Friday rose 1.7% to close at 4,280.15. The finish above 4,231 would mean the large-cap benchmark has recovered — or retraced — more than 50% of its fall from a Jan. 3 record finish at 4796.56.

“Since 1950 there has never been a bear market rally that exceeded the 50% retracement and then gone on to make new cycle lows,” said Jonathan Krinsky, chief market technician at BTIG, in a note earlier this month.
