Goldman Says Buying S&P After 5% Drop Is Usually Profitable

Buying US stocks after a slump of the scale witnessed over the past month has usually been profitable, according to a Goldman Sachs Group Inc. analysis of four decades of data.

Since 1980, the S&P 500 Index has generated a median return of 6% in the three months that followed a 5% decline from a recent high, according to the Goldman strategy team led by David Kostin. The benchmark has slumped 8.5% from its mid-July peak.

“Corrections of 10% have also been attractive buying opportunities more often than not,” although the track record is not as strong as after a smaller drop, Kostin wrote in a note. Returns after a 5% decline have been positive in 84% of episodes, the research shows.

A semblance of calm returned to global markets on Tuesday, with some of the worst-hit indexes rebounding from a slump driven by concern over a US recession and extreme valuations in the technology sector. Quantitative strategists at JPMorgan Chase & Co. said institutional investors had bought the dip Monday, with about $14 billion purchased during market hours and $6.7 billion sold at the close.
