Will the return of the pandemic cause S&P 500 index to tumble again in the future?

We suggest Volatility index for your reference. It reflects both the volatilities and the current level of market panics. Aside from S&P 500 index, there are also volatility indexes for China, Emerging markets, crude oil and gold. They can signal when you should reduce exposure.

Cboe Volatility Index

According to Cboe, the volatility indexes measure the market's 30-day expectation of volatility implicit in the prices of options. All indexes have a window of the future 30 days, except for S&P 500 index, which also has 9-day, 3-month and 6-month volatility indexes.
We display them in the following four categories:

The US Market

Non-US Market

Commodities and Forex

Single Stocks

Volatility in the Market

Small-cap stocks usually show greater volatility.

The US stocks

In the US stock market, for example, Russell 2000 shows higher volatility than large-cap stocks.

S&P 500 Volatility Index

In a bullish market, short-term volatility is lower than long-term volatility. So in normal times, VIX9D is the lowest and VIX6M is the highest.

Once the market starts panicking, however, volatility skyrockets and short-term volatility rises much faster than long-term volatility. As volatility rises, market risks increase.

Commodity Volatility

  1. Volatility index and its target share a negative correlation.
  2. Small-cap stocks show more volatility than large-cap stocks do.
  3. In normal times, short-term volatility is lower than long-term volatility.
  4. Volatility surges because of market panics.

What does it tell us?

While volatility index is usually viewed as a coincident indicator, we think S&P 500 volatility spread can tell us much more than that.

When 9-day and 6-month volatility spread turns negative— short-term volatility moves higher than long-term volatility— the market risks are high and investors should watch out for greater risks to come and reduce equity exposure.

S&P 500 volatility spread can thus been seen as an indicator for market risks.
