The only thing is, once you have enough time turners to control most of the volume of the market, there are no longer any linear-time causal inputs (read: people) deciding what directions the market will take. Market fluctuations would literally come from nowhere, though it might be best said that they would come from Time. And given Harry’s previous scary experiment (DO NOT MESS WITH TIME, ch. 17), I’m not sure it’s such a good idea to let Time be the one to control this.
