Editor's note: Welcome to "Barron's Roundup." Each weekend, Stockpickr presents portfolios related to articles in the latest issue of Barron's.

Top Natural Resource Plays: Barron's talks with MacKenzie Davis and Ken Settles, co-managers of the RS Global Natural Resource Fund (RSNRX). Davis and Settles believe that with some commodity stocks, you're not just buying natural resource producers, you're buying great companies. Among the stocks in their portfolio are Goldcorp ( GG), Agnico-Eagle Mines ( AEM) and Compass Minerals International ( CMP).


Bullish and Bearish: Each week, Barron's publishes bullish and bearish stories on a variety of stocks. We present summaries of those stories in this portfolio.

Bottom-Up Manager: Barron's talks with Aziz Hamzaogullari, senior portfolio manager of the $343.7 million Evergreen Large Company Growth Fund (EKJAX).
