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

Top Insider Purchases of the Week: Insider purchases are a lot more predictive than insider selling. Barron¿s lists the stocks where company managers or officials are buying, and we build a portfolio of those stocks. There's been interesting activity recently in Harley-Davidson ( HOG), Fannie Mae ( FNM), Marchex ( MCHX) and Six Flags ( SIX).


Barron¿s Summaries: Each week, Barron's publishes bullish and bearish stories on a variety of stocks. We present summaries of those stories in this portfolio. This week, there are bullish stories on Harley Davidson and Harrah's Entertainment ( HET).


Research Reports: The latest analyst research reports highlighted by Barron¿s. This week they include reports on Blue Coat Systems ( BCSI), Cyberonics ( CYBX) and Hewlett Packard ( HPQ).


Latest Activist Hedge Fund Purchases: Which companies are the top hedge funds chasing? This week's list includes names like Blockbuster ( BBI) and Transmeta ( TMTA).

At the time of publication, Altucher and/or his fund had no holdings in stocks mentioned, although positions may change at any time.
