What Is Buy to Open?
Let me explain what 'buy to open' means in options trading. It's a term brokerages use to indicate you're starting a new long position by buying a call or put option. If you're new to options and want to purchase one, you should use buy to open. This order tells the market you're opening a fresh position, not closing an existing one. To exit that position later, you'd use sell to close.
On the flip side, if you're establishing a short position, that's sell to open, and you'd close it with buy to close. So, if you want to sell a call or put to start, go with sell to open.
Key Takeaways on Buy to Open
You typically use a buy-to-open order to start positions in options or stocks. It can help you offset or hedge risks in your portfolio. When you buy to open an options position, you're setting up for potentially large gains with limited losses, but remember, there's a high chance the option could expire worthless.
Understanding Buy to Open Orders
Options trading terminology isn't as simple as stock trading. Instead of just buy or sell, you have to pick from buy to open, buy to close, sell to open, or sell to close. A buy-to-open order might signal to others that you have a strong view on the market, especially if it's a big order, but that's not always the case. Often, you're just spreading or hedging, where buy to open offsets other positions.
Here's something important: buying to open an out-of-the-money put when you buy a stock is a solid way to cap your risk. Keep in mind, though, that exchanges might restrict orders to closing only in certain situations, like if a stock is getting delisted or trading is halted. In those cases, your buy-to-open order might not go through.
Buy to Open in Stocks
You can apply 'buy to open' to stocks too. When you decide to add a new stock to your portfolio, that first purchase is buy to open because it starts the position. The stock stays in your holdings until you sell it all, which is selling to close. If you sell only part of it, the position is still open until nothing's left.
Buy to close comes up when you're covering a short sale. You borrow shares to short, then buy them back on the market to close it out—that final buy is buy to close, eliminating your exposure. The goal is to buy back cheaper for a profit, but if the price jumps, you might have to buy to close at a loss to avoid bigger hits. In the worst case, your broker could force a liquidation via a margin call, triggering a buy-to-cover order if your account equity is too low.
Buy to Open vs. Buy to Close
If you want to profit from a stock's price move by buying a call or put, you need to buy to open. This sets up a long options position with huge profit potential and low risk, but the stock has to move your way quickly, or time decay wipes out the value.
Option sellers benefit from time decay, but they might still buy to close early. When you sell options, you're locked in until expiration, but price changes let you lock in profits or cut losses sooner. For example, if you sell year-long at-the-money puts and the stock rises 10% in three months, buy to close to grab most profits now. If it drops 10%, you'd pay more to buy to close and limit damage.
Example of Buy to Open
Let's say you've analyzed XYZ stock and think it'll jump from $40 to $60 in the next year. You could buy to open a call with a $50 strike price expiring in about a year. That positions you to benefit if your prediction holds.
