Today, I asked GPT 5.6 to optimize the latest version of my investment portfolio tracker tool. It now supports not only adding US stocks, Hong Kong stocks, and crypto assets, but also A-shares, Japanese stocks, and Korean stocks—so you can track major global markets in real time all at once!


Besides that, this update also adds two new features.
One is that the total assets number can switch currencies, such as RMB or Hong Kong dollars.
The other is benchmark comparison, which lets you compare your own investment portfolio’s return-rate curve with those of major stock indexes, including the S&P 500, Nasdaq 100, Hang Seng Index, CSI 300, Nikkei 225, and the Korea Composite Index.
If I have time later, I’d like to wrap this investment portfolio tracker tool into a mobile app, so it can support importing portfolios from broker apps—it just feels more convenient for everyday use. If you’re interested, please like and leave a comment, haha!
