S&P 500 (SPY) divided by Gold (GLD) is starting to roll-over based on the shorter-term moving averages. This means that the S&P 500 is doing less well than the price of gold. If you rotate between the S&P 500 and the Gold ETF (GLD), you would be starting the shift from (sell) the S&P 500 and into (buy) the physical gold ETF – GLD. With the price of the S&P 500/GLD indicator now below 50-day moving average, and the 20-day MA about to drop below the 50-day MA, the S&P 500 rally is now on a short-term sell signal and a buy GLD signal.
