Systematic, regime-aware portfolio management
grounded in Modern Portfolio Theory.
The disposition effect is the most replicated finding in behavioral finance. Investors sell winners, hold losers, and abandon good strategies before they compound. Not occasionally — structurally. A system holds the position when you won't.
Markets are not one condition. They cycle through distinct environments, each with its own character. Evidence classifies them daily. Exposure responds accordingly — not from anxiety, from data.
Every allocation decision is governed by written parameters, agreed before the first trade. Transparent. Auditable. Non-discretionary by design. The default drives outcomes more than any individual preference.
Connect Alpaca or Charles Schwab. Choose a strategy. The system reads nine market indicators, classifies the current environment, and optimizes your allocation accordingly — then holds the course. You authorize the system — and it executes within those bounds. Evidence drives every rebalance.
