What is Market Volatility?
Market volatility is defined as the dispersion of returns of an asset or index.
Basically, market volatility is how much an asset is expected to move.
Stocks with higher expected volatility are expected to move more drastically and to larger extents than those with lower market volatility.
One of the primary measurements of market volatility is quoted on the VIX.
Let’s talk about this next so we can put market volatility in context, as a measurable variable.
Market Volatility for SP500 – VIX
The VIX is a measure for stock market volatility on the largest 500 companies in the United States.
VIX measures the expected 30 day variance of stock prices in the SP500 stock market index.
Market volatility values are expressed in percentages.
Before the Federal Reserve introduced a whopping amount of liquidity into the market (free money) the volatlity used to average around a 20% reading.
In 2017 markets experienced record low volatility, with the SP500 stock market index averaging around 11 on the VIX.
Looking at a weekly chart of market volatility for the SP500 stock market index, we come to a few important realizations about Market Volatility:
- Market volatility stays quiet, until it breaks higher in very violent fashion
- Market volatility is itself very volatile
- Stock market crashes lead to massive surges in volatility
- 2008: 420% rally in just 70 days
- 2010: 209% in 28 days
- 2011: 200% in 42 days
- 2015: 350% in 28 days
- 2018: 440% in 42 days
But at this point you must be wondering, what does market volatility mean and how do I use it for my trading strategies?
Let’s take a look at that next.
Market Volatility Used as a “Fear Index”
When stock market participants and traders expect a period of enhanced “uncertainty”, the VIX increases (market volatility in SP500 stock market index).
In trading the VIX is called the fear index. This is because market volatility tends to increase the fastest when fear sentiment in the stock market is increasing.
The VIX is the largest quoted index for market volatility by news outlets and most major publications.
Now that you know this fear index trait of market volatility how would you expect it to move against the stock market?
Overall as stock prices increase along with the indices, the overall fear index drops as market volatility drops.
Therefore, stock market prices and market volatility are said to be inversely correlated.
Here is a chart below that shows the relationship between the SP500 stock index and the market volatility index – VIX:
