what is volatility

Volatility is based on the historical price movements of the asset, and is calculated as the standard deviation of the asset price over a period of time. Beta is a measure of volatility, since it measures volatility in comparison to a performance benchmark . For instance, individual shares are usually considered to be more volatile compared to a stock-market index that contains different types of stocks. So, to avoid higher risks, lower risk investors usually prefer investing in securities that have less volatility risk because there is a guarantee of returns. Again to understand volatility better, investors will always assess a security’s beta. The beta gives an approximation of the overall security returns volatility against the relevant benchmarks returns.

XYZ, Inc. has a beta coefficient of 1.45, making what is volatility it significantly more volatile than the S&P 500 index.

That is, during some periods, prices go up and down quickly, while during other times they barely move at all. In foreign exchange market, price changes are seasonally heteroskedastic with periods of one day and one week. Also referred to as statistical volatility, historical volatility gauges the fluctuations of underlying securities by measuring price changes over predetermined periods of time. It is the less prevalent metric compared to implied volatility because it isn’t forward-looking. While variance captures the dispersion of returns around the mean of an asset in general, volatility is a measure of that variance bounded by a specific period of time. Thus, we can report daily volatility, weekly, monthly, or annualized volatility. It is, therefore, useful to think of volatility as the annualized standard deviation.

How do you know if market is up or down?

When reporters say the market is up, they often mean that the Dow Jones Industrial Average (DJIA), an index of 30 key stocks traded on the New York Stock Exchange and the NASDAQ, is up. If the Dow closed at 22,800 on Monday and at 23,000 on Tuesday, the market would be up at Tuesday's close.

Options investors may lose the entire amount of their investment in a relatively short period of time. So you’ll generally see variances in implied volatility at different strike prices and expiration months. Usually, at-the-money option contracts are the most heavily traded in each expiration month. So market makers can allow supply and demand to set the at-the-money price for at-the-money option contract. Then, once the at-the-money option prices are determined, implied volatility is the only missing variable.

Volatility origin

While we do that, we try to avoid those companies (e.g. oil and gas companies, coal miners etc.) whose business strategies do not align with our community’s values. That’s because we expect these companies, while they continue to be extremely volatile, to also underperform in the long run. Instead, we focus on those companies that are taking climate change seriously and are the future climate winners — and could benefit the portfolio and the planet as a result. The observation that low volatility stocks have higher returns than high volatility stocks in most markets studies. This is an example of a stock market anomaly since it contradicts the usual prediction that higher risk always equals higher returns.

What is a good volatility?

A beta of 0 indicates that the underlying security has no market-related volatility. Cash is an excellent example if no inflation is assumed. However, there are low or even negative beta assets that have substantial volatility that is uncorrelated to the stock market. The beta of the S&P 500 index is 1.

What we do know is that extreme events tend to be mean-reverting. In other words, when volatility is at historical lows, we can expect it to rise at some point towards the long-term average. The inverse is also true; when volatility is well above average, we can expect it to fall in the future. Yet, volatility is both a natural and necessary fact of investing in stocks. The adage, “no risk, no reward” still holds true as we put the 4th quarter in our rearview mirror.

Daily, σdaily, of given stocks, calculate the standard deviation of the daily percentage change for the stocks over a given time period. If the current economic and political situation is calm and there isn’t much uncertainty about the near future, most information will be priced into the stock market, making stocks less volatile. Meaning, in other words, that stocks won’t move about too much since people don’t expect too many things to change. If a stock is very volatile, you can expect large swings in its price and therefore a higher chance of making or losing money. In layman’s terms, the higher the volatility, the more of an emotional rollercoaster journey investors may experience.
