Now I really have seen it all ... A company that makes pot-dispensing machines had to put out a news release asking investors to chill. Shares of Medbox were selling at $4 on Monday but jumped to $215 on Friday — a staggering 3,000% increase — because the company got a favorable mention in a previous MarketWatch story headlined "How to invest in legalized marijuana." The tactic worked, at least a little. Shares were recently hovering around $100. "We believe an appropriate trading range is between $5 and $10 but, alas, the market will do what it will do," says company founder Vincent Mehdizadeh.
