...of the 11.93% expense ratio. This fund is like highway robbery!!! Even if it remains flat you lose 11.93% annually on your investment. However, that's if the price stays flat. If the price declines then you have to add your losses on top of the 11.93% expense ratio loss. Also if the price increases the fund would have to increase over 11.93% in order for the investor to make a profit.

In this sector (long interest rates, short bonds/treasuries), the next worst investment would be RYJUX. RYJUX is only 1 to 1 (no multiple inverse) and has a whopping 4.97% expense ratio. In fact, this would be worse than DXKSX as 2.5 (DXKSX Inv) x 4.97 (RYJUX expense ratio)= 12.425 expense ratio compared to DXKSX.

The best of the bunch is RRPIX with a fair expense ratio of 1.46% with a 1.25 inverse. Compare to DSKXS that would be equivalent to 2.92% expense ratio (1.49 x 2.5 inverse). Therefore, just put double your investment in RRPIX and get more return and a quicker than DXKSX with less downside risk/loss.
