Summary of Feb 2026

In January, I defended SaaS from AI risks for its incredible high switching costs and then further explained in the Best Buy series why they were also hard to operate even if AI can replicate the software part.

In Febuary, software continued to decline in Febuary. I have conducted a detailed AI risk assessment for all holdings. The finding showed AI is largely immaterial to 10 out of 12 businesses. However, I need to cut one holding - SPS Commerce (this week) and monitor one closely. I’ll also add more to two (patiently).

I could be wrong, of course! Valuation is at its lowest since IPO, and this particular business has also implemented its own AI capabilities.

However,

Its data structure is the problem! Deterministic, rule-based, and repetitive. SaaS with the same data structure, and with limited switching costs and network effects advantages, is likely to suffer the same fate.

Let’s look at the details of why I am trimming before we report the portfolio performance.
