There is a famous saying by legendary investor Warren Buffett – “Be fearful when others are greedy and greedy when others are fearful.”

Now that most investors have gone into panic mode due to the soaring oil prices amid the Iran war, should you be greedy?

Note that following the 2008 global financial crisis, global stock markets recorded a huge long-term rebound after bottoming out in March 2009.  The market bottomed out on March 6, 2009, with the S&P 500 hitting a low of 666, as quoted on CNBC. But the index delivered a 10-year annualized total return of 17.8% after that crash.

What Does History Suggest: A Strong Rebound Every Time?

The above rebound closely mirrors the annual returns (including dividends) delivered by the S&P 500 a decade after several major market turning points. Ten years after Black Monday in October 1987, the index posted annual gains of 17.2%, as quoted on the above-said CNBC article.

Returns reached 17.6% in the decade following the market bottom of August 1982, which marked the start of one of the greatest modern bull markets, the same CNBC article highlighted.

Even after the severe bear-market low of September 1974, the pattern was similar: the S&P 500 generated annualized returns of 15.6% through September 1984, as quoted on CNBC.

What Does the S&P 500 Say This Time?
