Investors seeking to break away from a top-heavy, market-capitalization-weighted index can take a look at a new breed of smart-beta exchange traded funds that equally weight components.

For instance, the ETFS Zacks Earnings Large-Cap U.S. Index Fund (NYSEArca: ZLRG) and the ETFS Zacks Earnings Small-Cap U.S. Index Fund (NYSEArca: ZSML) not only equally weight component stocks, but the two relatively new ETFs also equally weight sectors in an attempt to help provide greater diversification and better returns.

These funds “won’t move in lockstep with market-cap -weighted indices,” Mitchel E. Zacks, Managing Director and Portfolio Manager at Zacks Investment Management, said in a phone interview. Specifically, Zacks notes that ZLRG and ZSML both allocate the same weighting in each sector and the equal-weight methodology could drive outperformance in both of the ETFs.

In contrast, traditional market-cap-weighted indices may be top heavy and overweight stocks and sectors that have been outpeforming. During a market collapse, these same areas will likely be the hardest hit, dragging on market-cap-weighted fund.

Zacks argues that the equal-weight methodology would have outperformed, or at least mitigate the pullback, in the event of a broad decline. The strategist singles out the financials as among the largest sectors in the S&P 500 and the area exhibits some of the greatest swings during volatile conditions.
