Buy and Hold Strategy Can Pay Off

August 26, 2008 ( - A new Putnam Investments compilation of historical market data shows it may well be worth it for investors to resist the temptation of selling in a trough and keep their holdings until a market recovery.

A Putnam news announcement said the key take-away from the market data was that a market recovery will develop eventually and will benefit buy-and-hold investors.

Putnam said there have been 12 bear markets in the last six decades during which the markets plummeted a total of 22.4% before turning around after an average of 14 months.   The 12 bull markets since 1948 have lasted an average of 45 months, each growing an average of 123.9%.

According to Putnam, a $10,000 investment in the S&P 500 Index in 1988 would have grown to $72,932 by June 30, 2008, despite the 43% downturn of 2000-2002.

“Whether the current bear market has reached a bottom or not is unclear, but one thing we know from this study is that market gains have more than made up for losses for those investors who stayed invested over the long term,” said Elaine Sullivan, Head of Retail Marketing, in the announcement.   “The market has always recovered, but by trying to predict the best time to buy and sell, investors may miss the market’s biggest gains.”
