If you don't know what caused it, there is no need to be trying to figure out what it was, just try to use the opportunity you have got wisely and that's it. If you keep on looking out to find out what made the price to go upx then I'm sorry you're wasting your time and won't find out what.
I agree with what you say, and there is no point to search on why and why because there is more reason that we still don't know even if we dig for deeper.
It is better we use the opportunity that we have and follow the market movements, make the profit, buy at a low price and sell at the high price.
We don't have to waste our time to search everything because we have a limit to search and if you keep doing that, I am afraid that you will run out of your time and you will regret it later.
