A multi-strategy systematic approach to American equity markets.

We hold no prior. We report the posterior.

Passive Alpha is a multi-strategy systematic investment firm. We model the full distribution of macroeconomic outcomes, stress every candidate allocation against the regimes in which conventional diversification quietly stops working, and read the result the way you read an instrument — without arguing with it.

Method

Rigor in. Five hundred positions out.

Our research pipeline runs continuous factor decomposition, regime detection, and adversarial backtesting across thousands of candidate strategies. Three principles govern the apparatus.

01

Free from human bias

Our preferences are not an input; the allocation does not require them. No portfolio manager has ever overridden the model.

02

Exhaustive by design

Every candidate is evaluated in full — net of fees, slippage, taxes, capacity, and the behavioral drift that erodes returns in practice but never appears in a backtest. A conclusion is only worth holding if you have genuinely tried to break it.

03

We take the output

We don't take a view. We build the apparatus, we run the work, and we read the result. The more sophisticated strategies, examined closely, turn out to be leveraged or disguised expressions of the same exposure — purchased at a markup. We decline the markup.

Portfolio Construction

We don't hold a position. We hold five hundred.

The book is not a single bet. It is a maximally diversified, continuously rebalanced allocation across five hundred of the largest American enterprises — every sector, every cycle, weighted by the market itself. What the analysis recommends is not narrow. It is the broadest position available to a disciplined investor.

The Standing Conclusion

We ran the full analysis, as is our practice, and arrived where we always arrive — without surprise and without reservation.
