At Stockpickr.com, we keep track of the Top 10 Insider Purchases and Buybacks each week. Part of the philosophy of Stockpickr is to follow in the footsteps of smart people. This could mean a few different things.First, it could mean piggybacking great investors like Buffett or Soros. Other times it means buying what the CEOs, employees, and directors of a company are buying. These are people who know the intimate details of their companies far better than you or me. The perfect setup is when one of these company insiders or an entire board (in the case of a buyback) are buying shares as well as some smart savvy investors. Each Thursday we update the Stockpickr Top 10 Insider Purchases and Buybacks portfolio, featuring the 10 stocks of the week that had either big insider purchases or newly announced buybacks and also saw "smart money" accumulating shares. For instance, Chevron ( CVX) is in this week's portfolio. The second-largest U.S. oil company said it will repurchase $15 billion worth of common stock over the next three years. Over the last three years, the San Ramon, Calif.-based company has returned nearly $30 billion to shareholders through a prior $15 billion stock repurchase program as well as distributed $13.8 billion in common stock dividends. Chevron's latest numbers revealed a 24% year-over-year jump in profits, understandable in light of rising crude oil prices that are currently over $80 per barrel. And just this week, the chief economist from CIBC commented that oil could hit $100 per barrel by the end of next year and remain above that point for the foreseeable future. "We're in a world of triple-digit oil prices for the foreseeable future," said Jeffrey Rubin at a recent conference. This should bode very well for CVX earnings going forward.
