Crude and heating oil have been incredibly volatile these days, these are moves I haven't seen ever at this level of volatility, says Jerry Parker, CEO of Chesapeake Capital. He says he tries to not make too many trades during volatile times, and recommends keeping a well diversified portfolio. He discusses how the Japanese Yen (/6J) will act like a flight to quality sometimes when stocks sell off. The Japanese Yen is at seven year lows. He explains how the U.S. Dollar (/DX) compares to other currencies, and says it has been range bound against a lot of the European currencies and Australian and Canadian dollars. He discusses cotton futures, saying it is the strongest commodity.
