When to Use KBWP vs Berkshire

In this episode we answer emails from JT, Phil, and Glenn.  We revel in the updates to the TestFolio tools, weigh how tilting toward small cap value can lift safe withdrawal rates but also reduces overall diversification, return to KBWP and how property and casualty insurance companies can provide value-tilted diversification, and discuss the tracking results reported on the About page at the website.

Breathless Unedited AI-Bot Summary:

Ready to push past rules of thumb and actually pressure-test a retirement portfolio? We dig into how far a DIY investor can tilt toward small cap value to raise a safe withdrawal rate, what history really shows across 30- and 50-year windows, and why correlation—not bravado—decides whether you can keep spending through ugly markets. Using new Testfolio features with 100-year factor data, we compare the Golden Ratio and Golden Butterfly against more value-heavy mixes and pinpoint where the extra “cowbell” helps and where it just adds stress.

We also open a less-traveled door inside equities: property and casualty insurers. Whether you own them through KBWP or direct index the top names, this sleeve has delivered rare intra-equity diversification, often keeping pace with broad markets while zigging in years like 2022. We share the practical trade-offs—expense ratios vs. tracking error, simplicity vs. tax loss harvesting—and explain when the ETF is the smarter, lower-hassle choice. If you already own Berkshire Hathaway for your value core, you’ll hear why insurers can complement or substitute without bloating overlap.

Context matters, so we pull back the curtain on our publicly tracked taxable account and why it can look extreme in a bad year and strong in a good one. The whole-portfolio view is far steadier, closer to a risk parity blend of stocks, long treasuries, and diversifiers like gold and managed futures. The takeaway: if you want a withdrawal rate you can live with, build for multiple regimes—blend small cap value and large cap growth, keep long bonds for deflation shocks, and add real diversifiers that cut correlation when you need it most. Subscribe, share this with a DIY investor who loves data, and leave a review to tell us where you’d tilt next.
