Now that we've quantified all of the streaks of two-or-more consecutive days in which the S&P 500 was either up or down for every trading day since 3 January 1950, it's time to do something with the results of our deep data dive.
So we've taken the math we generated and built the following tool, in which you only need to enter the duration of a particular streak. We'll calculate the odds of a streak that long occurring, the odds of it being either a winning streak (multiple consecutive up days) or a losing streak (multiple consecutive down days), and also the odds of the streak lasting just one more day!
So, if a streak in the S&P 500 is underway and you're a speculator, the question is: do you feel lucky?
Well, do you?
