TakeoverChatter reports that Equity LifeStyle Properties (ELS) is one of five companies to hit a 52-week high June 20. The higher price may be the result of investors thinking the stock is undervalued, and their demand pushes the price higher. ELS Chairman Sam Zell recently led his company in acquiring 76 Land Lease Communities from Hometown America for $1.4 billion. Investors sometimes hear of company news that spurs the buying trend, and sometimes investors are speculating. Zacks says records show 1.1 million shares traded hands June 20, compared to a usual 30-day average of 366,000 shares a day. ELS, the largest Land Lease Community (LLC) owner in the nation, closed today gaining .70 percent.
