Regime-aware allocation beyond a single equity trend

A construction problem, not a forecast problem

Editorial: a single long equity run can be placed inside a multi-asset mix so a later market-regime change is handled as a construction task. Asset allocation and Diversification then set the sleeve weights. The analog describes what a decline might look like. It is not used to call the next tick.

Editorial: the working unit is the mix. A later selloff is treated as a change in regime that the mix has to absorb, rather than as a signal that must be timed in isolation.

A Japanese peak-to-trough analog

A historical Japanese equity peak-to-trough path was used as a regime analog for what a later US equity decline might look like after a long advance.

The analog sequence included a first-stage drop near 30 percent in four months, then a 22 percent rebound, then a further 40 percent decline. The path produced about a 49.2 percent loss in ten months and a 63.6 percent total decline by August 1992.

Where the then-current advance sat

A US intermediate-advance sample since 1896 counted nine rallies greater than 50 percent. The then-current advance was ranked seventh largest and fourth longest.

Unlike the other 50 percent advances in that sample, which began within 15 months of a major bottom, the then-current rally started on November 23, 1994, more than four years into the cycle.

A correction was defined as a selloff of one-third to two-thirds of the prior advance lasting weeks to months, with a first-leg estimate near an 18 to 20 percent decline in about 30 days.

Asset allocation as the main lever

Asset-class mix was treated as the dominant construction lever, with a cited study attributing 91.5 percent of portfolio profit to the chosen asset class rather than security selection inside the class.

A noncorrelated commodity or managed-futures sleeve was proposed as a way to cushion equity and bond declines without relying only on puts or short stock hedges.

Managed futures run by commodity trading advisors were judged, on the author's commodity-investing research, to outperform a long commodity index or a selected basket of commodities across both up and down periods.

A Sharpe ratio check on the mix

A backtested mix of 52.01 percent S&P 500, 30.34 percent Lehman Bond Index, and 17.65 percent CTA management produced a return-to-standard-deviation ratio of 2.70 over the compared period.

Editorial: that return-to-standard-deviation comparison is the Sharpe ratio style check on the mix. It compares an explicit quantitative baseline for the diversified sleeves, not a forecast of a single equity trend.
