Loyal3 offers no-fee trades, which includes buying and selling. The company even offers IPOs with certain balance requirements, but otherwise no minimum balance exists. This particular broker is best for beginners because your investments are limited to $2,500 or less per month. However, you can invest as little as $10.00 into a stock for free. Companies like Amazon, Apple, Google, Pepsico, and a few dozen others are available for trade. You can invest by bank transfer, debit, or credit card. For beginners, I think it's unbeatable. For veterans, it's probably not the best option. The no-fee structure is great for investors in general, though.
