As I mentioned in the comments yesterday, the market has had to expend a lot of buying power to overcome the large gaps down in the morning that we saw on Thursday and Friday. And all of that buying has pushed some indicators into overbought territory. One of which is the 3-day moving average of the TRIN. Take a look at this chart (click to enlarge):
The purple line at the top is the 3-day TRIN, and the SPX is below. When the purple line crosses the red line, you get a sell signal. This has been a very reliable indicator during this bear market, and the two black arrows show the last two times it raised the alarm. After each incident, the market pushed a bit higher, and then fell for several days.
If the market is able to make progress next week, it is likely to be short lived.
