Can Smart Beta think (twice)?

Forward looking analytics embedded in recent introductions of multi-factor Smart Beta ETF products demonstrate causality among its components and an ability to replicate past future pricing. Unclear is the extent to which Smart Beta indexes and related funds adequately discern the directional value of securities in aggregate at points of inflection to consistently outperform allocated Beta, Index-plus or Alpha portfolio strategies.

Certainly in capital market rally and recovery modes dynamic flat-weighted portfolio structures merit consideration for baseline benchmark index replacement. In this context however, as Small-Cap Growth and Mid-Cap Value asset classes are often alternating performance leaders, distinct valuation drivers typically reveal the limitations of Smart Beta’s construct. Performance dispersion among investment alternatives underscores the lag effects of set period-defined rebalancing, economic sector rotations and resultant fluidity within the traditional nine grid capitalization style box.

In initial review representative FTSE RAFI fundamental indexes, Smart Beta benchmarks plus corresponding Standard & Poor's and Russell indexes are detailed on a YTD, 12-month and 3/5/10 year basis:

Misleading perhaps in examination is Smart Beta's premise of interoperability in replacing benchmark indexes, sector/subsector proxies and conventional portfolio strategies as baseline comparables. The error in assignment is demonstrated by Smart Beta's inability to consistently outperform standard benchmarks in its own zero sum environment, that Alpha is Beta in market aggregation. Advocating alternatives to market capitalization-based industry standards (both style and size) without consistently discernable value-adds fails to significantly relieve portfolio manager and analyst responsibilities to monitor, evaluate and quantify changes in valuation over corresponding periods or alter the decision making process requisite in modifying portfolio weight allocations based on expected market conditions.
