CAOS — Alpha Architect Tail Risk ETF
CAOS uses S&P 500-linked option structures to express convexity and tail hedging alongside or instead of plain equity beta.

Total return (Yahoo adjusted close—dividends and splits per Yahoo), normalized to $10,000 at first available trade date. Educational only.
Strategy
CAOS is not a passive put ladder. Alpha Architect uses rules-based S&P 500-linked options (puts, spreads, or combinations) with explicit budgets for premium spend and roll cadence.
Theta bleed is the product: you are renting crash convexity. If implied volatility collapses after you buy protection, NAV can fall even when stocks are flat—size the sleeve as insurance, not core beta.
Manager and Issuer Pedigree
Alpha Architect built its brand publishing factor research and transparent rules before launching ETFs; CAOS inherits that culture—prospectus language tends to be precise about what is systematic versus manager discretion in vol environments.
Firm AUM is boutique versus BlackRock, but the sponsor’s audience is advisor-quant literate—expect frequent methodology blogs and updates when option markets environment-shift, which matters more for tail products than for vanilla indexers.
Outperformance
Outperforms when realized volatility and gap risk exceed what option prices implied: sharp drawdowns, correlation spikes, or liquidity events where convexity pays multiples of the carry burned in calm quarters.
Underperforms in grind-higher, low-vol bull markets and can lose fast if you buy protection into a vol spike that mean-reverts; favorable tape is episodic stress, not buy-and-hold compounding.
