Trading large volumes with penny profits per share
How do you know the shares will go up after you buy? The ultimate risk in your scenario is that you buy at a peak, and then that peak is never reached again. Over time, stock markets go up [more or less because there is a net increase in the overall production of the economy as time goes on]. However, you won't experience much of that gain, because you will be selling only after tiny amounts of profit have been achieved. So your upside is low, your plan is capital-expensive [because it requires you to have significant amount of cash available to make the initial purchase], and your downside [though unlikely] has massive risk.
