Why implied volatility

When determining a suitable strategy, these concepts are critical in finding a high probability of success, helping you maximize returns and minimize risk. You've probably heard that you should buy undervalued options and sell overvalued options.

While this process is not as easy as it sounds, it is a great methodology to follow when selecting an appropriate option strategy. Your ability to properly evaluate and forecast implied volatility will make the process of buying cheap options and selling expensive options that much easier. Make sure you can determine whether implied volatility is high or low and whether it is rising or falling. Remember, as implied volatility increases, option premiums become more expensive.

As implied volatility decreases, options become less expensive. As implied volatility reaches extreme highs or lows, it is likely to revert to its mean. If you come across options that yield expensive premiums due to high implied volatility, understand that there is a reason for this. Check the news to see what caused such high company expectations and high demand for the options. It is not uncommon to see implied volatility plateau ahead of earnings announcements, merger-and-acquisition rumors, product approvals, and other news events.

Because this is when a lot of price movement takes place, the demand to participate in such events will drive option prices higher. Keep in mind that after the market-anticipated event occurs, implied volatility will collapse and revert to its mean.

When you see options trading with high implied volatility levels, consider selling strategies. As option premiums become relatively expensive, they are less attractive to purchase and more desirable to sell. Such strategies include covered calls , naked puts , short straddles , and credit spreads.

When you discover options that are trading with low implied volatility levels, consider buying strategies. Such strategies include buying calls, puts, long straddles , and debit spreads.

With relatively cheap time premiums, options are more attractive to purchase and less desirable to sell. Many options investors use this opportunity to purchase long-dated options and look to hold them through a forecasted volatility increase.

In the process of selecting option strategies, expiration months, or strike prices, you should gauge the impact that implied volatility has on these trading decisions to make better choices.
