If I own an ETF (say based on the S&P 500) and also a short on a correlated index (e.g. SH), does that mean I am guaranteed to win in either extreme market condition? I simply sell the one that is high, hold the one that is low, use the profit to buy more of the low, then wait for the market to invert, and simply repeat the whole process?
Assuming you put the limit orders in for both, you're guaranteed to keep making money aren't you? Or am I misunderstanding what 2 inverted ETFs can do?
