With so much uncertainty about corporate earnings and when the global economy will start up again, it’s time to dust off investing strategies from the last crisis, UBS said in a note to clients.

Over a decade ago, a group of deep-value stocks were winners for investors through multiple parts of the cycle.

“Almost 40% of Deep-Value stocks outperformed the S&P 500 on the way down to its low in 2009 AND 21 of these ALSO outperformed in the rebound over the next six months,” the note said.
