We sold 86 shares of our Bank of America stock today for $17.50/share. We purchased 106 shares of the stock for $14.00/share back in January, so after fees, we earned over a 20% gain. That's a lot more than we would have earned keeping the money in our savings account for 9 months.
Selling the 86 shares basically cashes out the $1,500 that we originally invested. We're going to let the remaining 20 shares ride. This is money (currently ~$350) can now grow without any risk to our original $1,500.
