The worst week on the stock market since 2008 surprised some of Minnesota's top money managers and forced them to re-evaluate short-term forecasts and tactics.
"Clearly this week markets were trading on emotion," Carol Schleif, deputy chief investment officer for Abbot Downing in Minneapolis, said Friday. "Today, the only emotion it is trading on is fear."
For the fifth day in a row, stock prices swung lower and major indexes lost 12% in value as investors tried to assess the effect of the spread of coronavirus.
Market sentiment shifted from "FOMO to FOCO," the fear of missing out on a bull market to the fear of coronavirus outbreak, said Craig Johnson, technical market strategist for Minneapolis-based Piper Sandler Cos.
Schleif said she was surprised how quickly investors dropped their focus on fundamentals of corporate performance and valuation.
"When you get complacent about things, your time horizon goes way out into the future and you continue to project good times," she said. "When fear creeps in, your future thinking is 30 seconds from now."
Professional investors have been able to create models of other external events — like government shutdowns, worker strikes and Brexit votes — that drove other recent, but smaller, downturns in the markets.
Those events had V-shaped trajectories, or quick dips followed by quick recoveries, Johnson said.
