Tool I
Single Asset
Impact
Quantify how a single name propagates into total portfolio return. Adjust the position weight, the asset return and the rest-of-portfolio return — see contribution, net portfolio return and asset impact ratio in real time.
Rp = w1 × R1 + (1 − w1) × Rrest
Interactive · live chart
Tool II
Conviction
Sizing
Discount-to-intrinsic-value × conviction tier → target allocation. Convex, not linear. Zero at fair value, hard-capped at the concentration limit. Returns implied size, room to add and the recommended tranche.
target = f(conviction, discount, layer) · capped at 10% cost

How we use these tools

These models exist to answer two recurring questions in our process: "how much does this single name move the portfolio?" and "given my discount and my conviction, what is the right size for this position?"

Both tools take simple inputs and return numbers we use as a sanity check before sizing or rebalancing. They are not forecasts — they do not predict returns, do not adjust for correlation, and do not capture the qualitative work that drives our actual decisions.

The qualitative work — building conviction, understanding the moat, reading filings — happens elsewhere. These sliders are the last 1% of arithmetic before pulling the trigger.

"Sliders cannot substitute for the work of building conviction in the underlying business."
