A virtual investment firm
built as a $100 million experiment
in public market investing.
S² Capital is a virtual investment firm investing $100 million of simulated capital in real public markets.
We research companies, build positions, track them against live market prices, and document every investment decision — from first thesis to final outcome. We revisit those decisions over time, measure their performance, and examine what we got right, what we got wrong, and why.

- 03
Decision
Invest or pass, with the reasoning written down before any trade.
- 04
Position
Size the position, and state what would prove the thesis wrong.
- 05
Review
Revisit the thesis as new results and news arrive.
- 06
Exit
Sell when the thesis plays out, breaks, or capital has a better use.
04Methodology
S² Capital operates a simulated portfolio using real market prices. No actual capital is deployed.
Every decision is recorded with its date and reasoning, including the opportunities we missed and the calls we got wrong. Nothing on this site is investment advice.
