There have been five other times since 1980 that the Dow’s winning streak reached at least 10 days:
- 1/2/87-1/20/87 – 13 day streak
- 12/18/91-1/3/92 – 11 day streak
- 11/4/96-11/15/96 – 10 day streak
- 3/1/13-3/14/13 – 10 day streak
- 2/9/17-2/27/17 – 12 day streak
Using hedge fund analytics tool Kensho, CNBC ran a study to see what happens four months after the Dow’s streak ends.
Following at least 10 consecutive positive days, the Dow has traded positively in every instance since 1980, logging an average gain of 6.6 percent, four months later.
The S&P traded positively in four of five of those periods, returning an average of 4.88 percent.
