最近一直在关注更广泛的亚太股市情况，尤其是一些近期的走势。每个人都在谈论多元化的好处，通过将资金分散到日经指数、恒生指数、SET等来管理风险。很长一段时间以来，这都是完全合理的。不同的经济体，不同的驱动因素，对吧？
但老实说，有时感觉很多这些市场只是与全球情绪或美联储的最新声明同步波动，只是略有时间延迟。你看到一个重大的全球避险事件，突然间从$ZARJPY（目前在9.887，几乎没有波动）到日经指数的一切似乎都感冒了。我们真的在这里看到了真正的多元化好处，还是我们只是在多元化相关风险的风味？这就像房子里下雨时买不同品牌的雨伞。我开始认为很多“独特”的市场驱动因素已经被宏观因素所取代，以至于地理分散不再是一种对冲，而更多的是对相同潜在趋势的略微不同敞口。改变我的想法。
I think the correlation argument holds water; we've seen increasingly synchronized movements. However, I wonder if the magnitude of the moves still differs enough across these markets to offer some diversification benefit, even if the direction is often the same.
I've noticed that too. While long-term macroeconomic divergence still exists, the increasing interconnectedness of global capital markets means short-term correlations can be surprisingly high across what were once considered distinct regions. It makes you wonder if the traditional diversification playbook needs a refresh, at least for day-to-day volatility.
