The bank now expects global EPS to contract 30% in 2020, a marked improvement from a 50% drop it had expected at the height of the coronavirus crisis.

The estimate is a stark contrast to bottom-up analyst consensus of 18% contraction in 2020, which Citi said "looks too optimistic".

The U.S. bank sees MSCI all-country world stocks index <.MIWD00000PUS> to hit 705 by mid-2021, up 4% from current levels.

World stocks hit record high last week as unprecedented stimulus - $20 trillion and counting - is forcing a structural change in how financial assets are valued.

Citi said stocks look "expensive, but not ridiculously so", adding that central bank actions can sustain higher valuations across all equity markets.
