Based on these projections, I believe the stock is capable of reaching about $65 per share in as little as three years. At that rate of growth, by the end of 2014 you'd be looking at a bit more than a double from the current price of about $32 a share. This is assuming analysts are right about earnings growing 13.5% a year, which would put earnings at $4.32 a share at the end of 2014, and that investors continue to pay at least 15 times earnings for the stock as they have for the past couple years (15 X $4.32 = $64.80 per share).
Beyond that, it's much more difficult to say. The big question is whether Crown will turn out to be a stock for the long haul, or if competition from glass and plastic substitutes will begin to erode earnings to the point the stock loses the market-beating upside potential it has now. If you plan to buy the stock, then keep an eye on this and be ready to jettison shares if this scenario materializes.
