Local.com CEO and chairman Heath Clarke and several other top executives acquired over 500,000 shares in the company, according to SEC filings. Clarke alone acquired nearly 67,500 shares at $4.74, the price set on Friday's close. The filings follows weeks of rumors that a major search player would soon acquire Local.com, and would certainly make it easier for insiders to profit. But one industry source told me its as likely as not the rumors started with insiders at Local.com itself. That's something the SEC may want to take a glance at. But with or without Local.com's help, the local-search market continues to boom.
