Study: what happens next when the stock market's momentum is weak during an uptrend

The stock market’s momentum has been weak since January 2018 (because the stock market has been in a correction).
The S&P is up 2 weeks in a row this week for only the 3rd time in 4 months, while the S&P is still in an uptrend (i.e. is above its 52 week moving average). In other words, the S&P’s momentum has been weak over the past 4 months – it has rarely gone up for 2 weeks in a row.
Here are the S&P 500’s historical returns when this happened.

  1. What is our baseline? We know that in this case SP500 returns on a two week basis are positive 80% of the time. How does that compare with the 2 week basis for any random day? I’m curious about the baseline I should be comparing these bases to.
