This goes against conventional "wisdom", which states that a real rally should go up on rising volume. https://bullmarkets.co/study-a-stock-market-rally-on-low-volume-is-not-bearish/
While I don't necessarily agree or disagree with the conclusion, "studies" like this is extremely biased. The author picks 8 examples over the past 20 years which fitted with his point. I could've easily done the same and found 8 examples where the market rallied on rising volume. He should've quantified every major swing and it's volume impact over the last 20 years and provided empirical evidence. However yes "conventional wisdom" = usual textbook BS and should be questioned.
We will not crash this week. But we will next week. Let's see if the Artificial Intelligence prediction comes true. So far, it was correct each week of the month.
