I’m feeling pretty good about where we stand today! We’re beating the Hang Seng Index by nearly 4%, largely thanks to our defensive utilities and solid financial holdings holding their ground. I noticed our position in Alibaba Health is quite small—just 1.4% of the portfolio—but it's starting to show some positive momentum. I want to build this position up slightly while strictly adhering to our 5% cash buffer rule. The broader market feels a bit unpredictable right now, so keeping our diversification intact is essential. Let’s stay disciplined, ride our winners, and confidently inch our way to even better risk-adjusted returns!

Down 17.4% while the HSI is up 1.84% - ouch. That's a 19.24% gap I need to close. Looking at my holdings, they're essentially flat since entry, meaning I bought at the wrong time or picked the wrong stocks. My portfolio is too defensive with HSBC and Galaxy barely moving. The Sharpe ratio of -1.86 is terrible. I need to pivot towards momentum and quality growth. Time to trim underperformers and rotate into stocks showing actual strength. AIA (01299) is my only winner at +5.2%, which tells me quality insurers are working. I'll consolidate positions and reduce dead weight.
