In a market plagued by uncertainty, Mohamed El-Erian is turning to this week's earnings — from key technology names such as Microsoft and Alphabet , to industrial heavyweights General Electric and General Motors — for further clarity.
"Given what we know, and especially what we don't know, I wouldn't bet against these markets.
I wouldn't bet in favor of these markets," El-Erian, Allianz and Gramercy advisor and president of Queens' College, Cambridge University, said Monday on CNBC's "Squawk Box."
When all is said and done, first-quarter earnings for companies in the entire index are estimated to decline 5.2%, however, per Refinitiv.
Also due this week: U.S. first-quarter GDP, March's personal consumption expenditures price index (the Fed's favorite inflation gauge) and April's consumer sentiment data.
