To be sure, some DRIPs may require the ownership of, say, five or 10 shares to remain in the plan. However, you are under no obligation to buy stock on a regular basis in these plans. Of course, the power of dividend reinvestment plans is the ability to make regular investments with relatively little money. Still, you are under no obligation to do so. One exception is if you decide to sign up for automatic investment services in a dividend reinvestment plan.
Many DRIPs allow investors to make regular investments via automatic debit of a bank account.
In these instances, investors are obligated to invest on a monthly basis. A The beauty of dividend reinvestment plans is that your money buys both full and fractional shares. Your money is invested in the stock, not held until you have enough to buy a full share. Thus, all of your money is working for you right away in dividend reinvestment plans. I think you are probably better off buying a few DRIPs directly.
