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. HV can be used to assess by how much the price of a security shifts from its average value. In markets where a predominant trend exists, historical volatility provides an overview of the extent to which traded prices may have deviated from a central or moving average price. In smooth markets with a strong predominant trend, low volatility levels can be expected even though prices may fluctuate drastically as time passes.

Low volatility implies reduced uncertainty and risk, while high volatility is an indication of increased uncertainty and risk. Well, if the price is fluctuating rapidly, hitting new highs and lows very fast, the market may be considered highly volatile. Conversely, if the price is stable for a period of time, the HV may be within 2, or even 1, standard deviations, and that market will be said to have low volatility. Because finding the future risk of an instrument or portfolio can be difficult, we often measure historical volatility and assume that “past is prologue”.

- This indicator, which is good in strong trend movements, but totally useless in a flat, when the market price of a crypto-asset is at relative rest.

For example, if a fund has an alpha of one, it means that the fund outperformed the benchmark by 1%. Negative alphas are bad in that they indicate the fund underperformed for the amount of extra, fund-specific risk the fund’s investors undertook. Beta by itself is limited and can be skewed due to factors other than the market risk affecting the fund’s volatility.

Different sources may use slightly different historical volatility formulas, so you can get different values for the same asset with the same settings in different software. Investors expecting the market to be bullish may choose funds exhibiting high betas, mass index indicator which increases the investors’ chances of beating the market. If an investor expects the market to be bearish in the near future, the funds with betas less than one are a good choice because they would be expected to decline less in value than the index.

Besides the most popular HV calculation method described above, the calculator can also calculate HV using two other, alternative methods, including the zero mean (or non-centered) method. There is a user guide that comes with the calculator, which explains all the calculations in more detail.

It shows what happened in the past, which may not be indicative of what will happen in the future. This calculation may be based on intraday changes, but often measures movements based on the change from one closing price to the next.

Volatility is how much and how quickly prices move over a given span of time. In the stock market, increased volatility is often a sign of fear and uncertainty among investors.

- To annualize this, you can use the “rule of 16”, that is, multiply by 16 to get 16% as the annual volatility.
- On the other hand, a fund that in each of the last four years returned -5%, 17%, 2%, and 30% would have a mean return of 11%.

It gives traders the probability of whether there will be a volatile market going forward. There are many ways to measure volatility and each trader has their ways and tools for measuring it. Here, we are focusing on historical volatility, which is normally calculated as a standard deviation of price distribution about its moving average. Historical volatility (HV, for short) types of forex trades is a statistical indicator that measures the extent to which the price deviates from its average in a given period. It is important to note that historical volatility does not measure the direction of the price change, but just how much the price fluctuates. Volatility is also a key input in parametric value at risk (VAR), where portfolio exposure is a function of volatility.

Despite that sometimes it displays clear signals for entry on the daily chart. Note that all the indicator points to are historical prices and their average deviation from these values. We can look at a simple example of a strategy by adding a simple Moving Average indicator.

## Is Volatility the Same As Risk?

This measure is frequently compared with implied volatility to determine if options prices are over- or undervalued. Stocks with a high historical volatility usually require a higher risk tolerance. And high volatility markets also require wider stop-loss levels and possibly higher margin requirements. A fund with a beta very close to one means the fund’s performance closely matches the index or benchmark. A beta greater than one indicates greater volatility than the overall market, and a beta less than one indicates less volatility than the benchmark.

Implied volatility is observed in the market as the volatility implied in options’ prices. The only way to compute the IV is to use an options pricing model, such as the Black-Scholes Model, to solve for the volatility given the market price. 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.

## How this indicator works

When the two measures represent similar values, options premiums are generally considered to be fairly valued based on historical norms. Options traders seek out deviations from this state of equilibrium to take advantage of overvalued or undervalued options premiums. Sure, volatility (“vol”) means how much the price of a stock or index might change. High vol suggests the market anticipates bigger potential future price changes.

You can also use hedging strategies to navigate volatility, such as buying protective puts to limit downside losses without having to sell any shares. But note that put options will also become more pricey when volatility is higher. A high volatility can imply a possible change of trend when aggressive buying/selling enters the market because the large transaction volumes will trigger notable price reversals. Historical volatility does not specifically measure the likelihood of loss, although it can be used to do so. What it does measure is how far a security’s price moves away from its mean value. But nevertheless, you can use it for general estimation and behavior of crypto-asset for a specified period.

## Optimal Portfolio Theory and Mutual Funds

Growing unrest (orange) shows volatility increasing as the market is still in a bullish phase. When Black Monday rolled around, volatility went spiraling higher (red) before dropping off after the market stabilized (green). We do that by multiplying 1-day volatility by the square root of the number of (trading) days in a year – in our case square root of 252, which is approximately 16. Next we need to calculate standard deviation of the returns we got in the previous step. If you are using Excel, see How to Calculate Historical Volatility in Excel or a ready-made Historical Volatility Excel Calculator. If you are deciding on buying mutual funds, it is important to be aware of factors other than volatility that affect and indicate the risk posed by mutual funds.
