There is not specification to classify which one is blue chip, which one is not.

It is just a term being used to describe primarily on large cap and steady stocks. General low cap stocks won't be classified as blue chips, just like 'blue chips' in casino as posted, it refers to higher chip value one.

Hope it clear enough.

Feel free to further post in respective existing thread.
