The equities market has experienced a precipitous sell off, but stock exchange traded funds typically eked out a positive return in the following week, albeit at a slow pace.

The SPDR S&P 500 ETF (NYSEArca: SPY) was up 1.5% Tuesday but fell off 8% over the past week, with the S&P 500 index now hovering around 1,920.

According to Bespoke Investment Group, after the 28 times since 1980 the index experienced a weekly plunge of over 5%, the S&P 500 on average was up 0.5%, gained 1.7% over the next four weeks and increased 5% over the next 12 weeks, reports Julie Verhage for Bloomberg.

Additionally, after a weekly 5% or more plunge, the index exhibited a positive return 60.7% over the following week, 60.7% over the following four weeks and 71.4% over the following 12 weeks since 1980.

Tom Lee of Fundstrat Global Advisors also pointed out of the 11 previous times when the S&P 500 fell 9% or more in three back-to-back sessions, the market rose nine of 11 times in the following week, with a median return of 6.9%, reports Alex Rosenberg for CNBC.

Additionally, after three months following the three-day plunge, stocks saw a median return of 7.7%.

“Usually, a waterfall decline marks the end of a correction,” Lee told CNBC.

However, both Lee and Bespoke point out that the history has not always been favorable for a rebound. For instance, after the October 1987 plunge, stocks continued to plummeted 20.6% over the next 12 weeks, and after the October 2008 fall, stocks continued to decline 20.6% over the next 12 weeks.
