Fear index now highest since FebruaryThe Volatility Index (VIX), also known as the fear index, is a measure of forward expectation of risk on S&P forwards. Trading algorithms make use of this in pricing stocks.
Yesterday saw a large increase in the VIX and the market reacted with a corresponding sell-off. A contrarian would weigh a company's fundamentals and if favorable, would use the opportunity to enter the market.
With respect to pot stocks, keep your eye on the VIX. If it should come down, we should see an improvement in ACB stock price.
