AI agent pipeline that builds a single-sector equal-weight portfolio — critique + how would you diversify across sectors?
Disclosure up front: I built the tool that generated this. Not investment advice — paper only. Sharing because the output is what this sub critiques, and I want input on a design decision.
I've been building an agent pipeline that builds an equal-weight portfolio within a single sector. You pick the sector; it screens the names, the AI does the qualitative reasoning (macro/technical/fundamental), and a deterministic step handles the equal-weight allocation and trade math — the model never assigns the weights.
Here's a recent Technology run (equal-weight, ~20% each):
- MSFT
- ANET
- GOOGL
- META
- NVDA
The design choice I'm wrestling with: right now it's single-sector by design — deep within one sector rather than shallow across many. That keeps the comparison clean (every name faces the same sector tailwinds/headwinds) but obviously gives you zero cross-sector diversification.
What I'd love the sub's take on:
- For a single-sector book, is equal-weight the right call, or would you tilt by conviction?
- I'm planning a multi-sector mode next. Would you build it as equal-weight across sectors, cap-weighted by sector size, or risk-parity? Each has a very different risk profile.
- Single-sector concentration is the obvious weakness — how would you hedge it without abandoning the "go deep in one sector" premise?
Happy to explain how the pipeline reasons about any pick. (Tool link in a comment for anyone curious — not the point of the post.)
