Reverse Cap Weighting

Weighting by the reciprocal of market capitalization tilts index constituents towards the smaller end of the index, which exploits the small cap premium, reduces index concentration, and captures mean reversion.

Counter Momentum, Capture Value

Reverse-market-cap weighting addresses issues that are inherently created  by market cap weighting, which allocates more money to  large companies strictly because they are large. 

The Reverse Cap Weighted U.S. Large Cap provides access and broad exposure to companies that are under represented by traditional  market cap weighted indices which are susceptible to continually providing more capital to companies  and industries that are potentially overvalued, at the expense of investing in companies and industries  that may be under-valued.  

The reverse cap approach, through its rebalancing schedule, implements a disciplined buy low/sell high  strategy that may provide favorable risk-adjusted returns. 

What is the Reverse ETF Index?

How can Reverse cap weighting be used? 

The Reverse Cap Weighted U.S. Large Cap Index is a versatile index that can be used in a variety of  ways across all market conditions.


The Top 10% of the S&P 500 comprise more than half of the total index weight. By virtue of  the prevalence of cap weighted indices, those same names are over-represented across many ETFs.

Therefore, in periods of intense market stress, a broad sell off may disproportionally hurt the largest constituents of cap weighted indices.

In our  view, adding reverse weighting as a piece of a portfolios core large cap holdings is a great way  to diversify exposure while still investing in well know, well covered S&P500  companies.

A Tactical Product

Reverse ETF provides investors investors an instrument to add portfolio exposure  towards smaller cap companies within the large cap space, potentially benefiting  from smaller cap tailwinds while reducing the impact of the higher liquidity,  informational and volatility risks that “true small caps” may present.

Precision Targeting

When Investing in the total S&P 500 universe, portfolios can include a standard  market cap weighted product, or an equal weight product, with limited options in  between.

The Reverse Cap Index allows investors to precisely target their broad  S&P exposure, through blending the traditional S&P 500 and the Reverse Cap  Index to achieve any market cap weighting of the S&P 500 constituents to service the  unique needs, targets and market outlook of the investor with ease and flexibility.
