Wrong question, I think. The right one is "Is there even a such thing as a 'blue chip' stock?"
Which immediately leads into, "What timeframe are we talking about?" I might believe in a blue-chip classification on the time frame of five years as long as it isn't absolute, but there isn't a single company in existence anywhere (or anywhen) that I would guarantee will exist in fifty.
I think the entire idea of "blue chip" only works in a worldview raised not just before the 21st century, but in the earlier part of the 20th century (and before) where things generally moved more slowly and even a behemoth could take decades to fall. That's just not as true as it used to be, if for no other reason than in the 21st century said behemoth was likely to be leveraged to the hilt....
