Fidelity Investments has published a report that identifies the top 30 investment themes it believes are likely to have the greatest influence on the performance of each sector in 2012 and beyond.

Fidelity manages more than $40 billion in 44 sector-based strategies across the 10 major market sectors, such as consumer discretionary, health care and energy and subsectors such as gold and biotechnology, with 39 funds representing its Select Portfolios product line.

Over the past three years, nine out of the 10 Fidelity sector level Select Portfolios have outperformed their ETF peers, according to Fidelity. In addition, Fidelity's Select Health Care Portfolio, Select Technology Portfolio and Select Utilities Portfolio have beaten the S&P 500's historical average since their inception.
