Insiders Stock Up On These 5 Stocks Ahead Of Year's End

• Like other investors, insiders are positioning themselves for the near year.
• Intrexon and Prospect Capital are among those that have seen notable insider buying lately.
• Strong insider buying is often considered a positive sign for investors.

Like investors in general, insiders have been looking to position themselves to squeeze out any final gains for the year and prepare for 2016. Ongoing volatility does not appear to have dried up the level of insider purchases, perhaps a good sign as we head into the new year.Conventional wisdom says that insiders and 10 percent owners really only buy shares of a company for one reason -- they believe the stock price will rise and they want to profit from it. It should be no surprise that executives, directors and others are likely to continue taking advantage of any weakness they see.
