The investment seeks to match the performance of the Standard & Poor's MidCap 400® Index ("S&P MidCap 400 Index") as closely as possible before the deduction of fund expenses.

Principal Investment Strategies  

The fund normally invests at least 80% of its net assets in equity securities of companies included in the S&P MidCap 400® Index. The S&P MidCap 400® Index includes approximately 400 stocks of mid-cap U.S. companies in a wide range of businesses. The adviser employs a "passive" management, or indexing, approach, which seeks to match approximately the performance of the S&P MidCap 400® Index before the deduction of fund expenses.

Principal Investment Risks  

There is no guarantee that the Fund will achieve its investment objective. You may lose money by investing in the Fund. Please see the Fund’s prospectus or other disclosure documents for information about the Fund’s risks.

Fund performance is shown comparing it to a "benchmark" which may be a (i) broad-based securities market index (ii) a group of mutual funds with similar investment objectives, or (iii) a short term government backed debt obligation such as a U.S. Treasury Bill. An index is not available for direct investment, is unmanaged, and does not reflect the costs of portfolio management or trading. A fund's portfolio may differ from the securities held in an index.

Morningstar Information

Morningstar RatingTM   As of Dec 31, 2019
Period Stars Category Size
Overall 4 Stars361
3-Year 3 Stars361
5-Year 4 Stars292
10-Year 4 Stars220

The Morningstar Rating™ for funds, or “star rating”, is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange–traded funds, closed–end funds, and separate accounts) with at least a three–year history. Exchange–traded funds and open–ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk–Adjusted Return measure that accounts for variation in a managed product′s monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three–, five–, and 10–year (if applicable) Morningstar Rating metrics. The weights are: 100% three–year rating for 36–59 months of total returns, 60% five–year rating/40% three–year rating for 60–119 months of total returns, and 50% 10–year rating/30% five–year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
