Launched on 03/01/2006, the Invesco S&P MidCap 400 Pure Growth ETF (RFG) is a smart beta exchange traded fund offering broad exposure to the Style Box - Mid Cap Growth category of the market.
What Are Smart Beta ETFs?
The ETF industry has traditionally been dominated by products based on market capitalization weighted indexes that are designed to represent the market or a particular segment of the market.
A good option for investors who believe in market efficiency, market cap weighted indexes offer a low-cost, convenient, and transparent way of replicating market returns.
However, some investors believe in the possibility of beating the market through exceptional stock selection, and choose a different type of fund that tracks non-cap weighted strategies: smart beta.
These indexes attempt to select stocks that have better chances of risk-return performance, based on certain fundamental characteristics or a combination of such characteristics.
Methodologies like equal-weighting, one of the simplest options out there, fundamental weighting, and volatility/momentum based weighting are all choices offered to investors in this space, but not all of them can deliver superior returns.

The S&P MidCap 400 Pure Growth Index measures the performance of securities that exhibit strong growth characteristics in the S&P MidCap 400 Index.
Cost & Other Expenses

RFG's 12-month trailing dividend yield is 0.08%.
