A key insider has also done some big buying in Owens-Illinois ( OI), a manufacturer of glass containers with 81 glass manufacturing plants in 21 countries. It produces glass containers for beer, ready-to-drink low alcohol refreshers, spirits, wine, food, tea, juice and pharmaceuticals. This is another situation in which insiders are finding some deep value; the stock is off by over 42% so far in 2011. This company has a market cap of $2.91 billion and an enterprise value of $6.99 billion. The stock trades at a reasonable valuation, with a forward price-to-earnings ratio of 6.15. Owen's estimated growth rate for the next quarter is 20%, and for next year it's pegged at 23.6%. This is far from a cash-rich company -- its total cash position on the books is $260 million, and its total debt is over $4.3 billion. The CEO and chairman of the board just bought 121,200 shares, or about $2 million worth of stock, at $16.56 per share. From a technical standpoint, this stock recently collapsed from its May high of $32.32 a share to a recent low of $16 a share. The stock is now also trading below both its 50-day and 200-day moving averages, which is bearish. That said, the stock has started to form a basing pattern during the last few months between $16 and $19.60 a share. This pattern could be signaling that the downtrend is over and the stock has strong buying support at current levels. If you're looking to buy this stock, I would get long off any weakness below $19 a share. I would simply use a stop just below $16 a share in case the stock isn't done trending down. I would add to any long position once the stock trades above its 50-day moving average of $20.98 a share on above-average volume. The bottom line is that this name is attractive at current levels because it's only a few points off that $16 support level. It might not be a bad idea to follow the CEO into the stock here since it's also been so beaten down in the last few months.
