study investigates the impacts of the Standard & Poor’s (S&P) 500
Index, the NASDAQ Volatility Index (VXN), the spot prices of gold and silver,
and the U.S. Dollar Index (DXY) on the CBOE Volatility Index (VIX).
Specifically, the proposed arbitrage pricing theory (APT) model, programmed by
Python, performs multi-factor regression analysis that analyzes the degree of
impact measured by the beta coefficient of systematic risks on each factor. Our
samples include daily transaction data from 2007 to 2018, divided into three
periods to assess the VIX’s impact for each sub-period. The three periods are
entitled as the “Global Financial Crisis Period” (2007–2009), the “European
Debt Crisis Period” (2010–2012), and the “Follow-up Period” (2013–2018).
Empirical results show that the major factors are the S&P 500 index and the
VXN, with the DXY being a minor factor. Moreover, both gold and silver spot
prices have a significant impact on the VIX.
