How does it do that? This really is a math game. My wife has her doctorate in stochastics. Her opinion is that she can't develop an algorithm to predict the stock market unless she can pick and chose assumptions.
But what I can't get out of her is how does a stock performance change from one day to the next without any known position or event that would cause change to be known...
What I am saying is, Who is making all the decisions to make TSLA do what they want? It sure as hell ain't any of the people that love or hate TSLA.
There is apparently a fair bit of research that indicates that daily movements in the stock market and individual stocks are a random walk. If you drop those daily changes into a distribution, it's amazingly normal, with a very small # of outliers on the high side (stock going up) or to the downside (stock going down).
I believe that short term traders (and especially day traders) use this relationship to place a high number of small trades anytime there's a move one way or the other (as the short term normal distribution indicates it'll be coming back). If you can be consistently right 60% of the time over a high volume of equal sized trades, then you've pretty much got this casino dialed and you can retire.
