Ai can pick a stock but how far will the stock go? There are many factors that go into a rising or falling stock. For example if Ai would pick Canadian Tire A as the next stock to go up the news of this would be known to many people who would start to buy the stock, but as the stock becomes over valued the big financial institutions would start to sell until it becomes fair valued for the market. Then the cycle will start all over again. This has been happening before Ai, the only thing Ai may change is the speed at which the stock market rises and falls.
