The following screenshot is from Bespoke weekly report. In my opinion, a Golden Crosses, is always a short-term sell signal because we all know that Moving Averages crossover (as well as MACD buy/sell signal) is a lagging signal therefore if you follow it the way it’s supposed to be, i.e. long when bullish crossover while short when bearish crossover, you’ll have lots of whipsaws, so why in most cases, trade against it?
