Our goal is demonstrating skill at capturing alpha from lower market exposure portfolios under most market conditions. We build concentrated, equal-weight equity portfolios of 22 securities spread across all 11 GICS sectors, rebalanced as signals decay, averaging about 50 trading days and capped at 90.
Alpha comes in two forms: absolute alpha measures total return regardless of market direction, while relative alpha isolates excess return over a benchmark, what the manager actually contributed beyond what an index would have delivered for free.
We hunt relative alpha. Our benchmarks are the equal-weight S&P 500 (RSP) and the cap-weight S&P 500 (SPY). The spread between our portfolios and those indices is the signal we care about.
Where appropriate, we use derivatives to reshape risk and extract asymmetric payoffs that linear portfolios cannot reach, such as risk-managed and market-neutral variants. None of this is decorative. Every position exists because it improves the odds of capturing alpha on the days the market structure allows it.
Our proprietary framework classifies each trading day as either Alpha Opportunity or Pure Beta based on market conditions. On Pure Beta days, correlations spike and even good picks get swamped by index-level forces. We do not confuse surviving those days with skill. We measure what we can control, on the days it can manifest, and we build everything around that distinction.
We present live results every day at 1:30 PM Pacific in our AC Monitors for transparency. The numbers are there whether they flatter us or not. Every claim is tested daily against the live record: Statistical Validation →
