Entropy a new measure of stock market volatility
An Unbiased Reexamination of Stock Market Volatility. N. GREGORY MANKIW. Search for more papers by this author Recent work demonstrates serious statistical problems with standard volatility tests. This paper proposes new tests that are unbiased in small samples and that do not require assumptions of stationarity. Entropy: A new measure of research the standard deviation is still the most popular measure of volatility being used as a benchmark for comparing the forecast ability of more complex models. 3. Theoretical framework: the concept of entropy An alternative way to study stock market volatility is by applying concepts of physics which The primary measure of volatility used by traders and analysts is standard deviation.This metric reflects the average amount a stock's price has differed from the mean over a period of time. More precisely, what we want to find out is if Tsallis entropy is able to detect volatility in stock market indexes and to compare its values with the ones obtained from the standard deviation. Also, we shall mention that one of the advantages of this new methodology is its ability to capture nonlinear dynamics.
Measuring Stock Market Volatility: Measuring the S&P 500 on the VIX The composition of the VIX was changed in 2003. At that time, the CBOE created a “new” VIX by making two changes to the

For the daily data, the

We used a sample based on the daily returns of the G7's major stock market indices. The results show the limitations of the standard deviation-based approach in fully characterising volatility and highlight the potentialities of entropy as a measure of uncertainty.

This paper proposes new tests that are unbiased in small samples and that do not require assumptions of stationarity. Entropy: A new measure Buckle up. After a relatively calm year in 2017, volatility in the stock market has returned in a big way. The most often cited measure of volatility, the Cboe Volatility Index or VIX, has

On one hand, substantial changes in volatility of financial market returns are capable of having significant negative effects on risk averse investors. In addition,

Based on the data from the Chinese financial market, this paper focuses on analyzing three types of network entropies of the financial market, namely, Shannon, Renyi and Tsallis entropies. The findings suggest that Shannon entropy can reflect the volatility of the financial market, that Renyi and Tsallis entropies also have this function when their parameter has a positive value, and that We used a sample based on the daily returns of the G7's major stock market indices. The results show the limitations of the standard deviation-based approach in fully characterising volatility and highlight the potentialities of entropy as a measure of uncertainty.
