In the No. 3, Cramer added Direcxion Daily Financial Bull 3X Shares (FAS)" along with its bearish counterpart that trades under "FAZ." Cramer said these funds are designed solely for day traders and claim to offer three times the return. But Cramer noted that these funds reset daily, wiping out gains if not sold daily.

In the No. 2 spot was U.S. Natural Gas Fund (UNG) a fund Cramer has panned previously. Cramer said this fund has done nothing recently, despite a major move in natural gas. Why? He said the fund, which doesn't buy gas, buys gas futures, which it then must roll over every month, again wiping out gains.

Last on Cramer's hit list was PowerShares DB Crude Oil Double Short ETN (DTO). Cramer said in addition to its totally confusing name, this fund is confusing as to what it does. He said it supposedly tracks a basket of futures contracts, but the fund is set up to trade like a note, rather than a fund. Cramer said there are all sorts of inherit regulatory risks for this this fund, and investors need to steer clear.
