FYI: 2017 will go down in stock market history for its volatility. Not because there was a lot of it―quite the opposite. The year featured one of the least-volatile stock markets in history, including a maximum drawdown of 2.8% (the smallest in history) and an average absolute daily price change of 0.3% (also the smallest in history).
The most famous gauge of U.S. stock market volatility, the Cboe Volatility Index—VIX for short—reflected the unusually tranquil backdrop of 2017. It fell to as little as 8.56, the lowest level ever for the gauge, which had broken below 9 only once before in its history.
