The VIX was created by the Chicago Board Options Exchange as a measure to gauge the 30-day expected volatility of the U.S. stock market derived from real-time quote prices of S&P 500 call-and-put options. It is effectively a gauge of future bets investors and traders are making on the direction of the markets or individual securities. The standard deviation essentially reports a fund’s volatility, which indicates the tendency of the returns to rise or fall drastically in a short period of time. A volatile security is also considered a higher risk because its performance may change quickly in either direction at any moment. The standard deviation of a fund measures this risk by measuring the degree to which the fund fluctuates in relation to its mean return.
Assessing the risk of any given path — and mapping out its more hair-raising switchbacks — is how we evaluate and measure volatility. Not surprisingly, volatility is often seen as a representative of risk in investments, with low volatility signaling safety and positive results, and high volatility indicating danger and negative consequences. Conversely, a stock with a beta of .9 has moved 90% for every 100% move in the underlying index. Central banks around the world use interest rates as a tool to either stimulate economic growth or curb inflation. A change, or even the anticipation of a change, in these rates, can have profound impacts on everything from bond yields to stock valuations.

- If the options prices start to rise, that means implied volatility is increasing, all other things being equal.
R-squared values range between 0 and 100, where 0 represents the least correlation, and 100 represents full correlation. If a fund’s beta has an R-squared value close to 100, the beta of the fund should be trusted. On the other hand, an R-squared value close to 0 indicates the beta is not particularly useful because the fund is being compared against an inappropriate benchmark. Continuing with the Netflix example, a trader could buy a June $80 put at $7.15, which is $4.25 or 37% cheaper than the $90 put. Or else the trader can construct a bear put spread by buying the $90 put at $11.40 and selling or writing the $80 put at $6.75 (note that the bid-ask for the June $80 put is $6.75 / $7.15), for a net cost of $4.65.
When there is a rise in historical volatility, a security’s price will also move more than normal. At this time, there is an expectation that something will or has changed. If the historical volatility is dropping, on the other hand, it means any uncertainty has been eliminated, so things return to the way they were.
You then back-solve for implied volatility, a measure of how much the value of that stock is predicted to fluctuate in the future. “Companies are very resilient; they do an amazing job of working through whatever situation may be arising,” Lineberger says. “While it’s tempting to give in to that fear, I would encourage people to stay calm.
Meaning of volatility
Such fluctuations can be influenced by a myriad of factors including economic data, geopolitical events, market sentiment, and more.

As an investor, you should plan on seeing volatility of about 15% from average returns during a given year.

The rationale for this is that 16 is the square root of 256, which is approximately the number of trading days in a year (252). This also uses the fact that the standard deviation of the sum of n independent variables (with equal standard deviations) is √n times the standard deviation of the individual variables. As an indicator of uncertainty, volatility can be triggered by all manner of events.
