### Implied Volatility Explained

Implied volatility (IV) measures the likelihood of a change in the price of a security. It helps investors where their investment will move in the future by forecasting the supply & demand and the security price movement, which in turn helps to understand the price of options contracts. It is based on certain factors (which include the market expectation of the security’s price) that impact the price of a security and are usually expressed in percentage of the stock price, indicating a standard deviation that relates to a specific period. The symbol used to denote Implied Volatility is σ (sigma).

It relies on market consensus and depicts the outlook of the market. If market expectations increase or demand increases, implied volatility increases, increasing the options premium price component. Inversely, if the market expectations fall or demand for the security drops, implied volatility also decreases and decreases the options premium price component.

It is a measurement of the change in the price of security shortly. In a bearish market, it is high since investors assume that the security price will fall, whereas in a bullish market, it is low since investors assume the price will go up in the future. It plays a major role in deciding the pricing of options.

**Formula**

The formula which acts as the basis of **implied volatility calculator **is discussed below. It shall help us under this concept and related factors in detail.

**How To Calculate?**

The method most often used by traders and fund managers is to find the market price of the particular option and incorporating it into the Black-Scholes formula.

After incorporating it, they back-solve the equation to find the volatility of the option. A few other options for determining the **implied volatility chart **include iterative search and trial and error method.

**Indicators**

The movements in the market are beyond the control of any player. However, the movements are always indicators of what is to follow. Let us understand the indicators of an **implied volatility chart **through the discussion below.

- Implied volatility does not depict whether the price movement will be positive or negative.
- High implied volatility means that there will be a large price swing. It may either move higher in the upward direction or very low in the downward direction or might swing too much in between both ends.
- Low implied volatility means that the price swing will be minimal.
- It differs from historical volatility, which measures the volatility based on historical data.

### Examples

Let us understand the concept of an **implied volatility calculator **with the help of a couple of examples. These examples will give us insights into the intricacies of the concept.

**Example #1**

Pixer LLP stocks are currently trading at $50 per share in the market. Suppose the market assumes that the share price will rise, which will result in an increased demand for the shares. Since the demand for the shares increases, there will be an increase in implied volatility, which will make the premium for the option much higher.

Let’s assume that the implied volatility for this stock is 20%. The lowest price in one year was $32, and the highest in the same year was $64. The market predicts the price to move within 20%.

- 20% of $50 upwards is $60
- 20% of $50 downwards is $40

The market assumes that the stock’s price by the end of the year will be between $40 and $60. As per the theory, 68% of the market assumes that the price will be within the range mentioned above, whereas the remaining 32% think that the price will fall below $40 or go above $60.

As an investor, looking at the numbers, the most appropriate strategy can be adopted for the investor to reap maximum profits from their investment. Although, these calculations are based on market consensus and are not foolproof, and might result in a loss of investment for the investor. But looking at the figures, one can decide what strategy needs to be adopted for a particular security. The market might not move as expected by the market consensus, as seen in many past incidents where the market behaves purely differently from what the market participants expect it to do.

**Example #2**

Full House Resorts, Inc. is a casino operator and developer based out of Nevada. They operated five casinos in 2023. In July 2023, experts warned the investors in this stock as the stock price reached $5 per share.

It had one of the highest implied volatility among all equity options in the period. It also showed a ‘SELL’ tag for the gaming industry on the whole as prominent traders did not increase their investments in this area and their earnings had been reduced from 14 cents per share to a mere 8 cents per share.

However, the option trends might suggest that there is heavy trading activity being formed. Traders would hope that the share does not move as much as it was originally predicted to move to make significant premiums.
