Your point is well made and I totally agree with you. There is absolutely no point trading Gold in Tokyo if you're already trading Gold in Chicago.
Sorry can’t agree with this at all. I could list many examples, but just to take a few … Rubber, Korean Bonds, Palm Oil … on what Chicago exchanges can you get exposure to markets that have any correlation to these three. (btw I realise that CME do in fact have a Palm oil contract but it has zero liquidity compared to 50,000 contracts traded daily on Bursa Malaysia)
Regarding equity indices, then sure if you’re holding longer-term positions you will naturally be exposed to the same global events. But let’s assume that you day-trade a particular price action that works well for you on an intraday basis. Why would you focus solely on Chicago markets when you can apply the same methodology to the Hang Seng, MIB, KOSPI or many others that are trading in a totally different time-zone, thereby providing that free lunch of diversification.
We can also consider arbitrage position between markets like Chicago Wheat v LIFFE Wheat v Milling Wheat or Sugar#5 v Sugar#11.
I could go on and on, but let me just respectfully suggest that not everything outside of your Chicago hometown should be regarded as either the same or as “exotic”. Take a closer look and I think you’ll be pleasantly surprised at the benefits that will accrue by taking a truly global approach
