Although the strategy can get complex, the basic principle behind stocks seems simple enough: Buy and sell or buy and hold.
But buy and lease? How do you rent out a stock?
The answer: 100 shares at a time.
The more traditional name for this practice is the covered call, an investment strategy that involves options. You sell or write call options against shared of stock you already own — in other words, you sell someone the right to purchase stock you own at a specific price and within a certain period of time. Ally Bank says a single option contract usually represents 100 shares, so you'd need to own at least that amount for every call contract you plan to sell with this strategy.
If the stock price reaches the strike price, the buyer can exercise their option and you would assign the stocks. The covered call is typically a long-term strategy for people who intend to hold their stocks and don't anticipate a price increase anytime soon. You earn income via the premiums and if the stock price does rise past the strike price, you aren't in trouble because you deliver something you already own.
Of course, it gets much more complicated and there can be significant capital gains scenarios to consider. As with any investment strategy and financial planning, consult with a professional to chart the best course for you.
