For the SPXU, rebalancing appears to be keeping this fund in lock step with the S&P 500. The chart above shows the SPXU tracking just as it should be. I keep reading warnings that leveraged ETFs rebalance every day, which can erode the position. The only thing I see eroding a position in the SPXU is whether or not the S&P 500 happened to close below the investor’s entry point into the position, no different than the expected behavior on any other stock in the market. Your stock goes up; your stock price goes up. In the case of the SPXU, the S&P goes up; the SPXU goes down in a parallel manner at 3X leverage.
Caveat: I suspect that most investors may not have the stomach for the volatility of trading such a fund, and if you are not able to weather large swings of up to 15% and beyond on a daily or weekly basis, then this fund is definitely not for you, because if the market runs against your position, you could get wiped out. Therefore, probably 99% of all investors should avoid this fund like the plague.
Disclosure: I am long SPXU, starting October 19.
