It could be true that the market can continue to grow well past 15% above fundamentals for the indefinite future. But the more it goes up, the more improbable it becomes.

If you've flipped heads three times in a row, you're right that I would look foolish saying the next one can't be heads. But at the same time you cannot keep flipping heads forever.

true on all accounts but comment like OP made is ridiculous. to say “for sure XYZ will happen to the market by this date” is childish/funny/insane. to say “eventually” there will be a correction is similar cause of course there will be. so all this talk about bubble and other shit is just nonsense all around
