Since I start investing in stocks, I notice that almost everytime that everything crashed, it's the during the monday stock market opening.
Is there any data, or insights, regarding this matter ? (Maybe it's just psychological)
And if that's really something, is this a dumb idea to auto-sell everything before the stock market closing et buy back a few hours after the opening depending of the actuality ?
I CLEARLY do not pretend that it is a good idea, I'm just wondering.
