Most experienced investors think they're past the beginner mistakes. They're not.

After building and analyzing hundreds of portfolios, I keep seeing the same 3 errors — even from people managing $200K+.

1. Over-diversification disguised as risk management

If you own 40+ positions, you don't have a portfolio — you have an index fund with higher fees. True risk management isn't about more positions. It's about understanding correlation clusters and sizing correctly within them.

2. Ignoring sequence-of-returns risk

A 30% drawdown needs a 43% gain to recover. Most investors optimize for average returns when they should be optimizing for worst-case path dependency. The order your returns arrive in matters more than the returns themselves.

3. Static allocation in a dynamic market

"Set it and forget it" is advice for people who don't want to learn. Markets cycle. Regimes shift. A portfolio that was optimized for 2020 conditions is bleeding in 2026. Adaptive allocation isn't market timing — it's discipline.

I built McKelvin Capital to solve exactly this. Inside, I share the institutional-grade frameworks I use for allocation, risk management, and portfolio construction.

If you're managing real capital and want to stop leaving returns on the table — this is for you.
