Markets run in cycles—sometimes up and sometimes down. The good news is that put options are available to investors trying to protect themselves from or take advantage of the downside. It's essential to understand the risks as well as the potential benefits.

You hold some stocks in your portfolio, but you're not comfortable with the thought of them dropping below a specified level. Is there a way to protect those stocks from sharp price drops? Options aren't always for speculation and were initially designed for risk management. Put options can be helpful to protect from a decline in the holding shares, just as we insure our homes and cars. How does this work? Let's see!
A put buyer is entitled to the right to sell 100 XYZ shares at a fixed price (known as a strike price) within a specified period. The below contract allows the put buyer to sell 100 XYZ shares at $155. Suppose the buyer chooses to exercise his right to sell the underlying shares. In that case, he will receive total proceeds of $15,500 meanwhile delivering his XYZ shares to the counterparty.

Here's an example: Say you own XYZ stock trading at $160 per share and worry about how some potential news may affect its near-term prospects. So, you may buy the above put option, which costs you $177. If XYZ stock drops below $155 by 19 Aug 22, the buyer can still sell the shares at $155 no matter how low the market price is. Thus, you've capped your risk to the downside of the stock. When the stock price remains sideways or trends upside, it is not economical to exercise the put option, so the put option is likely to expire worthless. The investor keeps the potential profit if the stock continues to rise while holding the underlying assets.
Reading this far, you may already notice that buying puts on your stocks is like your home insurance. Knowing that your stock position can be protected from a loss may make you feel more comfortable. Therefore buying puts on your stocks is called Protective Put Strategy.
During downtrends, the average investor may react like this: i) He watches his portfolio lose value and does nothing, hoping the market will eventually turn around. ii) he takes money out of the market and hopes that the market doesn't turn around immediately.
It's likely that neither choice feels like a good option.
The good news is that some options strategies are proactive and may be appropriate for long, sustained bearish markets. Let's start with the basic bearish strategy: Buying puts.
Suppose you expect the stock XYZ may drop significantly, so you buy the XYZ $155 19 Aug 22 Put for $1.77. Therefore, you have the right to sell XYZ at $155 before expiration. Unlike the above Protective Put Strategy, you buy the put option without holding the underlying asset. If this bearish view is correct, you can exercise the put option and sell the stock at the strike price higher than the market price. Of course, since the XYZ is currently at $160, you're in no rush to exercise your right.
If XYZ settles at expiration at $155 or higher, the put expires with no value, and you lose $1.77, or $177 per contract (100 shares per contract). No matter how much higher than $155 per share XYZ settles ($200, $500, even $1,000 per share), you lose what you paid for the put option, or a 100% maximum potential loss is there if the stock price moves against you. The put option works quite differently than short-selling stocks, as there is a limit to the financial loss no matter how wrong you are.
As you can see, if the stock drops way below $155, say to $140 per share, you can buy the stock at $140 and sell it at $155 by exercising that put. The difference between those two prices is yours to keep. The lower the stock drops, the more the buyer can profit via the long put strategy.
Both buying put options and short selling are bearish strategies, for they are profitable as the market drops. The two strategies have features in common, but investors should understand the difference.
Short selling is only permissible in margin accounts with equity above $2k. Buying a put can be an alternative if your account is a cash account or you have a balance under $2k. So investors can take active trading strategies instead of just looking at the bear eating away at their portfolio. Moreover, some shares are not available to sell short, whereas put options on those non-shortable securities may be an alternative.
One difference we have mentioned is that the maximum potential loss of buying puts is what you already paid for the contract, no matter how expensive the price rises. In contrast, a short seller may face an unlimited risk as the stock's value can climb infinitely.
Short sellers should also meet the margin requirements and must have the funds in the account to cover the short position. As the price of the shorted asset rises, the maintenance requirement to cover the position will also rise, decreasing the remaining available balance. Conversely, put options cannot be held on margin and can only be purchased with cash.
This lesson covered two scenarios about buying put options:
