In my first blog post in early October 2011, I recommended purchasing DDI Corp, a small technology company that provides printed circuit board engineering and manufacturing serices. At the time, the stock was selling at about $7 per share and yielding 5.5%. In early April, Viasystems agreed to purchase DDI Corp for $13 per share. Anyone who happened to read my post on DDI Corp and purchased the stock made nearly a 100% return in 6 months. Not bad.
