An April 22 post to Ask Our Pros by Dan Fitzpatrick,

No ETFs That Short, requires clarification. The post should have indicated that the ProFunds UltraShort and Rydex Inverse funds theoretically match 200% of the inverse performance of not only the Dow 30 but also may use various other benchmark indices. Also, it is important to note that there are some inverse funds that may use shorting, as well as derivatives and futures, to meet their performance objectives.

A May 3 story,

Oil Falling Back Toward $50 a Barrel, incorrectly characterized a statement by John Felmy of the American Petroleum Institute. The story mistakenly said Felmy believes a floating currency in China would lead to lower worldwide oil prices. In fact, Felmy believes a floating currency could lead to higher worldwide prices.
