Stocks trim losses, still on pace for worst week since March

Stocks are swinging between slight and sharper losses Thursday, as Wall Street’s hopes for a relatively quick economic recovery continue to collide with skepticism that it can happen anytime soon.
The S&P 500 dropped to a quick loss of 1.9% in the morning, only to erase virtually all of it by midday, before falling back again. It was down 0.2%, as of 12:15 p.m. Eastern time. Stocks in Asia and Europe fell to sharper losses, while Treasury yields sank in a sign of increased pessimism.Th
