Past pandemics such as 2003's SARS saw equities markets quickly bounce back from their lows once the rate of infection in secondary outbreak sites slowed. While China has effectively curbed contagion within its borders, escalating outbreaks in the US, Italy, and Iran prompted fresh selling as investors traded risk assets for safe havens.
The stop to economic activity in Europe and the US will further harm markets before they recover. Historic amounts of fiscal stimulus will be required to keep the event-driven bear market from turning into a prolonged downturn, Goldman said. The rebounds seen after past crises were fueled by consumers' quick return to regular activity, and such recovery amid the coronavirus pandemic is unlikely, according to the bank.
"The fear factor around the economic shock from preventative measures may push markets down further in the meantime," Oppenheimer added.
