Why Uncorrelated Has Become a Marketing Term Rather Than a Structural Claim

Almost every alternative strategy is sold on the same promise. Returns that move independently of equities. A smoother path through the cycle. Diversification at the moment it actually matters.

Then a stress event arrives and the lines converge.

The problem is not that allocators have been misled. It is that a correlation coefficient is being asked to carry more meaning than it can hold. Correlation is a backward-looking summary of a particular sample. Change the window, and the number changes with it. A long calm stretch produces low correlation almost mechanically, because nothing is compelling participants to sell the same assets at the same time.

Stress removes that comfort. Positioning is unwound, liquidity thins, and strategies that appeared independent turn out to have been leaning on the same benign conditions all along. What looked like separation was shared exposure to an environment nobody thought to name as a risk factor.

This is why the honest question is not whether a track record shows low correlation. It is whether the return source is structurally independent of market direction, or whether it merely appeared to be while conditions permitted. Those are entirely different claims. One is measured after the fact. The other is designed in advance and holds regardless of what the sample happens to contain.

The distinction matters most for allocators building portfolios out of components. If three managers each show low correlation to equities but all depend on stable liquidity, the portfolio is far more concentrated than the pairwise numbers suggest. At EC Assets, direction independence is treated as a structural requirement of the strategy rather than a statistical outcome to be reported afterwards. The firm's view is that what cannot be explained structurally should not be relied upon defensively.

Diversification that only holds in calm markets is not diversification. It is a coincidence with a good chart.
