One will be 15 yuan, a slaughtered hen value of 5 yuan, the former is blue chip stock, the latter is not blue chip stocks. As the former sells to 100 yuan, it is blue chip stock because it will go down; but it is not a value shares, because the eggs under the birth of the chicken are born to chicken, or sell less than 100 yuan, overdraft. If you sell 1 yuan, it is not a blue chip stock because it does not increase the ability to increase production; but it is worth 5 yuan, the current price is as cheap. Both are the relationship of this metaphor.
