What is volatility? Definition and meaning

The former indicator plots two bands – one upper and one lower band – at a distance of two standard deviations from a centrally-located moving average. In general, the more the bands widen, the higher the volatility of the underlying instrument. The following chart shows period of low and high volatility, identified by using Bollinger Bands. A less volatile asset, on the other hand, would hardly move at all. Combining financial instruments with different volatilities can also be used to diversify the investment risk in a portfolio.

Despite the low volatility, there is still much money to be made from the most liquid market in the world. Traders can either increase the frequency or trade size to make up for the lack of intense movements or use a tool called leverage to amplify movements.

Mathematical definition

Since then, the VIX is one of the most frequently used to gauge market volatility and investor sentiment by market participants such as traders and investors. In the context of the stock market, volatility is the rate of fluctuations in a company’s share price (i.e. equity issuances) in the open markets.

For stock traders who look to buy low and sell high every trading day, volatility and risk are deeply intertwined. Volatility also matters for those who may need to sell their stocks soon, such as those close to retirement. But for long-term investors who tend to hold stocks for many years, the day-to-day movements of those stocks hardly matters at all. Volatility is just noise when you allow your investments to compound long into the future. Stock market volatility is a measure of how much the stock market’s overall value fluctuates up and down. Beyond the market as a whole, individual stocks can be considered volatile as well.

If the volatility history is less attractive, then the firm has to wait until the stocks price normalizes so that it can sell it at a profitable price. However, because of unpredictability, a stock that is highly volatile may happen to go down further before it picks up again. More active, shorter-term investors use volatility to make buy and sell decisions much more frequently. Day traders aim to buy low and sell high multiple times over the course of a single day, and swing traders do the same over the course of days or weeks.

Commodities Market Volatility

When there is market volatility, it is an indication that there is either an upward or downward price movement in the market. So, when the market becomes volatile, bullish traders tend to increase prices on commodities on what they regard to be a good news day. On the other hand, bearish traders, as well as short-sellers, take advantage of this to bring prices down on what they term as a bad news day. Volatility is also used to price options contracts using models like Black-Scholes or binomial tree models. More volatile underlying assets will translate to higher options premiums because with volatility there is a greater probability that the options will end up in-the-money at expiration. Options traders try to predict an asset’s future volatility, so the price of an option in the market reflects its implied volatility.

For the entire stock market, the Chicago Board Options Exchange Volatility Index, known as the VIX, is a measure of the expected volatility over the next 30 days. The number itself isn’t terribly important, and the actual calculation of the VIX is quite complex. Implied volatility takes five metrics — the option’s market price, the underlying asset’s price strike price, time to expiration, and the risk-free interest rate — and plugs them into a formula . You then back-solve for implied volatility, a measure of how much the value of that stock is predicted to fluctuate in the future. Volatility does not measure the direction of price changes, merely their dispersion.

Forecasting models has to be measured in statistical tests, comparing the forecasts to the actual values of the target variable, which is a form of realized volatility here. The VIX index is often used as a proxy for the current market volatility level. Volatility is not inherently a negative sign for investors, but investors must still understand that the potential for outsized returns comes at the cost of incurring significant losses. Beta, on the other hand, is “backward-looking” and compares a stock price’s historical changes to changes in the broader market. The implied volatility and beta are both measurements of a stock’s volatility. In valuation, one common measure of volatility is called “beta (β)” – which is defined as the sensitivity of a security to systematic risk relative to the broader market.

Portfolio managers use volatility to evaluate overall portfolio risk, as input interactive brokers review into optimizers, for value-at-risk calculations, as part of the stock selection process, and to develop hedging strategies. Derivatives desks use volatility to price options and other structured products. In addition, plan sponsors use volatility to understand the potential that they will or will not be able to meet their long-term liabilities and financial obligations.
