After nosediving 33.9% between February 19 and this past Monday, March 23, the Standard & Poor's 500 stock index rebounded sharply and ended the week about 13% off its bear market low.

While the vicious plunge may resume, signs that the worst of the coronavirus bear market may be over began to emerge.

JP Morgan and Goldman Sachs both forecast an unprecedented contraction in the second quarter ending June 30, 2020, followed by a third quarter surge in growth. Goldman Sachs expects a mind-bending 24% contraction in the second quarter while J.P. Morgan forecasts a 14% slowdown in Gross Domestic Product.
