Longer-Term Oil Volatility Not Too Bad

Interesting chart over at the Bespoke Investment Group site showing how the 50-day average of the daily percentage spread between high and low crude oil price is near the average of the last ten years. Of course, daily price moves are bigger, and short-term volatility may in fact be higher. The results are interesting nonetheless. It would also be interesting to see a longer chart coving some of the 1970s in inflation adjusted terms.
