$1,000 Buy into your company's stock purchase plan. Many public companies offer employees the opportunity to buy its stock at a reduced price. Generally, your employer takes money out of your paycheck every month on an after tax basis and, every six months, uses what's accumulated to buy you stock at a discount (usually around 15%). In six months, your $1,000 will buy you $1,200 worth of stock so you've already made money. Over time, your investment will increase as your company's stock grows.
