Fidelity Mid Cap Enhanced Index Fund

Transcription

1 Fidelity Mid Cap Enhanced Index Fund Key Takeaways The fund gained 1.72% for the six months ending August 31, 2017 the period since our previous annual report lagging the 3.24% increase in the benchmark Russell Midcap Index. The fund was hampered by its elevated exposure to low-valuation companies and corresponding underweighting in growth- and momentum-oriented investments, as growth stocks significantly outperformed value stocks this period. Stock picking in the consumer discretionary sector hurt relative to the Russell benchmark, with several struggling brick-and-mortar retailers finishing among the fund's biggest detractors. The fund benefited from its positioning in the energy sector, with a combination of modestly favorable stock picking and a helpful underweighting resulting from our bottom-up security-selection approach adding value. Senior Manager Max Kaufmann and his team continued to employ an investment model designed with the goal of identifying companies with strong fundamental characteristics they believe may be correlated with long-term outperformance. The team's data-driven approach is intended to help reduce emotional biases and generate a more objective investment decision-making process.

3 Q&A Fund Facts Trading Symbol: Maximilian Kaufmann Manager FMEIX Start Date: December 20, 2007 Size (in millions): $1, Investment Approach Fidelity Mid Cap Enhanced Index Fund is a diversified domestic equity strategy with a mid-cap core orientation. The fund seeks to outperform its benchmark through a quantitative investment process that balances both risk and return. Our approach involves building multifactor statistical models to help us select companies with desirable fundamental characteristics. We generally favor companies with improving fundamentals and that are also trading at reasonable valuations. Our systematic investment process accounts for both topdown market indicators and bottom-up fundamental insights, using a dynamic factor allocation that allows the fund to adapt to changing market conditions in a riskaware manner. An interview with Maximilian Kaufmann, Senior Manager of the Geode Capital Management, LLC, investment management team Q: Max, how did the fund perform for the sixmonth review period ending August 31, 2017 The fund gained 1.72%, trailing the 3.24% return of the benchmark Russell Midcap Index. The fund edged the peer group average during the same time frame. During the period, mid- and small-cap stocks each lagged the S&P 500, a proxy for the overall U.S. large-cap market, by a few percentage points. Meanwhile, large-cap growth stocks, as measured by the Russell 1000 Growth Index, significantly outpaced their large-cap value counterparts, as measured by the Russell 1000 Value Index, with a narrow slice of large-cap technology companies increasingly responsible for growth stocks' significant outperformance. Looking out a bit further, the fund was up 12.70% for the 12 months ending August 31, 2017 slightly better than the 12.44% gain in the Russell Midcap Index and meaningfully outpacing the peer group average. Q: What factors influenced the fund's results for the past six months After the U.S. presidential election last November, the prospects of lower corporate taxes and deregulation raised investors' expectation for economic growth dynamics that, as we approached the reporting period, had been benefiting cheaply valued companies. Beginning in 2017, however, and continuing through period end, political gridlock in Washington dampened investors' optimism, leading to a reversal in the performance of cheap stocks. Unfortunately for the fund, our relatively high exposure to lower-valuation stocks within the mid-cap universe hurt. At the same time, growth and momentum were desirable characteristics the past six months, but our generally low exposure to these factors muted the positive impact on the fund. Such positioning was, as always, the product of our 3 For definitions, fund risks and other important information, please see the Definitions and Important section of this Q&A.

4 quantitative approach to investing. This involves building systems that select investments with a variety of desirable fundamental traits that our research has shown to be correlated with potential long-term outperformance. Ultimately, we're seeking to identify good businesses with durable competitive advantages and with stocks that are selling at what we consider reasonable prices. To accomplish this objective, my team and I use computeraided analytical models to help us examine and rank individual securities. With these models, we build a portfolio that seeks to outperform the benchmark. These rankings generally are based on factors such as valuations, earnings growth and technical indicators. In general, we seek to establish a risk profile for the portfolio similar to that of the index. Our models are designed to provide a framework in which we may decide to overweight securities that our quantitative process shows have more exposure to the fundamental factors we believe can lead to outperformance, and underweight those that have little to no exposure to such characteristics. In addition, we consider the fund's security, industry and market-capitalization weightings relative to the benchmark. We generally invest at least 80% of the fund's assets in common stocks included in the benchmark, but maintain the ability to invest in non-index securities if our models identify attractive opportunities elsewhere. Q: Why do you favor a data-driven approach One important reason is our view that financial markets are less than 100% efficient, primarily due to investors' behavioral tendencies. In an effort to reduce the influence of human emotion and potentially eliminate some common investing biases that affect both institutional and individual investors we apply a systematic investment process grounded in traditional fundamental security analysis to make the process more objective. Q: What decisions influenced results relative to the Russell benchmark Stock picking in the consumer discretionary sector proved the biggest drag on relative performance this period, with exposure to several brick-and-mortar retailers hurting most. An increasingly competitive business environment weighed on footwear retailer Foot Locker, home products retailer Bed Bath & Beyond and department store chain Macy's all of which our models favored for the companies' extremely low valuations. Those valuations went even lower during the period, however, and, at the recommendation of our models, we added to our position in all three stocks. The fund was well-positioned in the energy sector. Modestly favorable stock picking here added value, along with an underweighting in this lagging category, which was a byproduct of our bottom-up process. That said, because persistently sluggish oil prices hindered the financial results of many energy stocks this period, our relative overweighting in exploration and production company Southwestern Energy detracted from the fund's performance. Our top individual contributor was NVIDIA, a graphicsprocessing company that produced strong earnings and revenue. As the period progressed, our models continued to like certain aspects of NVIDIA's business but found the company's stock less attractively valued over time. We ultimately sold the fund's stake in late June. Also contributing was Pilgrim's Pride; our investment in the chicken producer was up about 44%. For much of the period, our models found the stock attractively valued albeit somewhat less so over time while also noting its improving price momentum. Note to shareholders: During 2018, Fidelity's Large-Cap, Mid-Cap and International Enhanced Index Funds will begin investing all or substantially all of their assets in a "master portfolio." The master portfolio will be an affiliated mutual fund with an investment objective and investment strategies substantially the same as the existing enhanced index mutual funds. This is commonly referred to as a master-feeder structure. In this structure, a fund does not invest in securities directly and instead invests in a master portfolio that, in turn, invests directly in securities. Fidelity will file preliminary registration statements for five multifactor, enhanced index exchange-traded funds (ETFs) with the Securities and Exchange Commission (SEC) that, if approved, also will invest in the master portfolio. In order to facilitate the conversion of the Large-Cap, Mid- Cap and International Enhanced Index Funds to a masterfeeder structure, the following changes were made: the fiscal year-end of each fund changed to August 31 from February 28; and each fund is now allowed to pay dividends quarterly instead of semiannually, and capital gains once a year instead of twice. In addition, pursuant with the conversion, the funds will disclose the full holdings of the underlying master portfolios daily with no lag, rather than the current monthly disclosure with a 30-day lag. 4 For definitions, fund risks and other important information, please see the Definitions and Important section of this Q&A.
