Howe Caverns is a premier natural attraction, a living, limestone cave, carved by an underground river over the course of 6 million years, located 156-feet below the earth's surface. An Schoharie County, N.Y. farmer discovered the caverns more than 160 years ago. Formed in 1927, Howe Caverns incorporated, a public company owned by shareholders, opened the caverns to the public on Memorial Day weekend of 1929.
Definition of 'Volatility'. Definition: It is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease.
The VIX Index is the most common measure of market volatility. It uses the price of options to estimate the implied volatility. We've gone through some periods where that VIX Index got to almost record levels, especially after the financial crisis. But it mean-reverts.
