Nowadays it is easy to trade all kinds of asset classes from a single brokerage account, including all your varieties of global macro. So let's make a list of best and worst markets to trade nowadays. 1) For sure, gold is is trending, sufficiently liquid nowadays, what more do you want? 2) T-bond. Easier to predict long term than S&P500 imo. 3) USD/JPY. Very politically driven, unlike Euro (hard to read the ECB). On the minus side: 100) Oil: Can't figure it out, do not understand the supply. 99) S&P 500: King of the wiggle.
