In September 2019, JPMorgan Chase determined the effect of US President Donald Trump’s tweets, and called it the Volfefe index combining volatility and the covfefe meme. Casual market watchers are probably most familiar with that last method, which is used by the Chicago Board Options Exchange’s Volatility Index, commonly referred to as the VIX.

- The use of the historical method via a histogram has three main advantages over the use of standard deviation.
- 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.
- Blue-chip corporations historically perform well and yield a positive return, while small-cap, more growth-oriented corporations might have large returns with periods of high volatility.

One recommendation is to request the investment performance information from the investment management firms. However, the necessary information can also be obtained by gathering the monthly closing price of the investment asset, typically found through various sources, and then manually calculating investment performance. In the periods since 1970 when stocks fell 20% or more, they generated the largest gains in the first 12 months of recovery, according to analysts at the Schwab Center for Financial Research. So if you hopped out at the bottom and waited to get back in, your investments would have missed out on significant rebounds, and they might’ve never recovered the value they lost. As an investor, you should plan on seeing volatility of about 15% from average returns during a given year.

As described by modern portfolio theory (MPT), with securities, bigger standard deviations indicate higher dispersions of returns coupled with increased investment risk. Strictly defined, volatility is a measure of dispersion around the mean or average return of a security. Volatility can be measured using the standard deviation, which signals how tightly the price of a stock is grouped around the mean or moving average (MA). When prices are tightly bunched together, the standard deviation is small. When prices are widely spread apart, the standard deviation is large.

## Types of Volatility

In contrast, a low volatility means that the price of a security will not change dramatically in short periods of time. Typically, volatility will have more impact on investment strategy in a bearish market as investors see their returns plummeting which adds to their stress during a downturn. A beta of more than one indicates that a stock has historically moved more than the S&P 500. For example, a stock with a beta of 1.2 could be expected to rise by 1.2% on average if the S&P rises by 1%. On the other hand, a beta of less than one implies a stock that is less reactive to overall market moves.

For example, resort hotel room prices rise in the winter, when people want to get away from the snow. They drop in the summer, when vacationers are content to travel nearby. That is an example of volatility in demand, and prices, caused by regular seasonal changes. Volatility is a prediction of future price movement, which encompasses both losses and gains, while risk is solely a prediction of loss — and, the implication is, permanent loss. In the non-financial world, volatility describes a tendency toward rapid, unpredictable change. When applied to the financial markets, the definition isn’t much different — just a bit more technical.

That said, let’s revisit standard deviations as they apply to market volatility. Traders calculate standard deviations of market values based on end-of-day trading values, changes to values within a trading session—intraday volatility—or projected future changes in values. Market volatility is measured by finding cm trading broker review the standard deviation of price changes over a period of time. The statistical concept of a standard deviation allows you to see how much something differs from an average value. You then back-solve for implied volatility, a measure of how much the value of that stock is predicted to fluctuate in the future.

To utilize this method, investors simply need to graph the historical performance of their investments, by generating a chart known as a histogram. Changes in inflation trends, plus industry and sector factors, can also influence the long-term stock market trends and volatility. For example, a major weather event in a key oil-producing area can trigger increased oil prices, which in turn spikes the price of oil-related stocks. Regional and national economic factors, such as tax and interest rate policies, can significantly contribute to the directional change of the market and greatly influence volatility. For example, in many countries, when a central bank sets the short-term interest rates for overnight borrowing by banks, their stock markets react violently.

First, the historical method does not require that investment performance be normally distributed. Second, the impact of skewness and kurtosis is explicitly captured in the histogram chart, which provides investors with the necessary information to mitigate unexpected volatility surprises. Third, investors can examine the magnitude of gains and losses experienced. In order for standard deviation to be an accurate measure of risk, an assumption has to be made that investment performance data follows a normal distribution.

The most simple definition of volatility is a reflection of the degree to which price moves. A stock with a price that fluctuates wildly—hits new highs and lows or moves erratically—is considered highly volatile. For example, Netflix (NFLX) closed at $91.15 on January 27, 2016, https://forexhero.info/ a 20% decline year-to-date, after more than doubling in 2015. Traders who are bearish on the stock could buy a $90 put (i.e., strike price of $90) on the stock expiring in June 2016. The implied volatility of this put was 53% on January 27, 2016, and it was offered at $11.40.

## Stock Volatility

For a financial instrument whose price follows a Gaussian random walk, or Wiener process, the width of the distribution increases as time increases. This is because there is an increasing probability that the instrument’s price will be farther away from the initial price as time increases. Unfortunately, with a highly volatile stock, it could also go much lower for a long time before it goes up again.

Over a period of one year, Company A’s shares were considerably more volatile than Company B’s.

Above all, volatility will impact investing strategy as in general rational investors don’t like too much swing (ups and downs) in their investment returns. But extent of this impact will depend on the investment horizon, composition of the current portfolio and investor’s risk tolerance. Stock market volatility is a measure of how much the stock market’s overall value fluctuates up and down.

This is why the VIX volatility index is sometimes called the “fear index.” At the same time, volatility can create opportunities for day traders to enter and exit positions. The VIX is the CBOE volatility index, a measure of the short-term volatility in the broader market, measured by the implied volatility of 30-day S&P 500 options contracts. The VIX generally rises when stocks fall, and declines when stocks rise.

This means that Netflix would have to decline by $12.55 or 14% before the put position would become profitable. The VIX is intended to be forward-looking, measuring the market’s expected volatility over the next 30 days. Much research has been devoted to modeling and forecasting the volatility of financial returns, and yet few theoretical models explain how volatility comes to exist in the first place. The Volatility Index or VIX measures the implied volatility of the S&P 500. If you’re close to retirement, planners recommend an even bigger safety net, up to two years of non-market correlated assets. That includes bonds, cash, cash values in life insurance, home equity lines of credit and home equity conversion mortgages.

## Is High or Low Volatility Better for Stocks?

The effects of volatility and risk are consistent across the spectrum. Most typically, extreme movements do not appear ‘out of nowhere’; they are presaged by larger movements than usual or by known uncertainty in specific future events. Whether such large movements have the same direction, or the opposite, is more difficult to say.

In general, high volatility can increase the potential returns of an investment, but also increase the potential losses, while low volatility can reduce the potential returns, but also reduce the potential losses. Therefore, investors should consider their investment horizon, risk tolerance, and investment objectives when assessing the impact of volatility on their portfolio. A security is said to have a higher level of volatility when its value can change dramatically in a short space of time. Volatility is measured using the tool of ‘standard deviation’, which measures an asset’s departure from the average.
