Oct 22 (Reuters) - Global equity funds saw robust inflows in the week to Oct. 20, boosted by optimism over third-quarter corporate results, which eclipsed worries over higher inflation. The four largest U.S. consumer banks posted strong quarterly results this month as the rebounding economy allowed them to release more cash they had set aside for pandemic losses, while sizzling deals, equity financing and trading also boosted their bottom lines. Among sector funds, financials received a net $1.46 billion, marking a fourth straight weekly inflow.
