# My feed is flooded with talk about Tau (τ) Law. What's the difference between it and Moore's Law?

I've been quite busy the past couple of weeks, so there will be fewer article updates. Today, I'll just briefly talk about Huawei's Tao Law that's been flooding the feed.

According to reports, Huawei will launch a Kirin mobile phone chip based on the Tao Law this autumn, adopting "logic folding technology." The most critical process enhancement, "logic folding," is essentially 3D packaging.

**Simply put, it's like building a bungalow and a flat road before, but now building a duplex and an overpass, stacking digital, storage, and analog circuits vertically in 3D.**

This differs somewhat from the previous Moore's Law, whose primary beneficiary has been TSMC's advanced processes. Under the new concept of Huawei's Tao Law, some domestic semiconductor equipment manufacturers are worth watching in the future. On one hand, it covers the big beta under the overall AI demand, while also having the logic of import substitution. Under the new law, there might be a chance to overtake on the curve in the future, but this still requires focusing on the selection of specific stocks. I checked the net value at night, and the top gainers were funds heavily weighted in the semiconductor-related sector.

These funds, if concentrated in a single holding, can be quite volatile, and it's also hard to predict such incidental events in advance. However, advisory portfolios like Watchmaker Active Alpha, while maintaining balance, also allocate to some tech growth funds. This way, it's actually possible to participate in the offensive opportunities of related sectors in a more stable manner.
