irrational markets

Two quotes to ponder from economist John Maynard Keynes. I searched this morning and found this first one, a variant of which I've been saying for years. I really wanted to think it was my own creation. I'm glad I looked it up, as I found this second quotation updating opinions to follow facts rather than updating "facts" to follow opinions.

Markets can remain irrational a lot longer than you and I can remain solvent.
---- John Maynard Keynes

When the facts change, I change my mind. What do you do, sir?
---- John Maynard Keynes

Thank you wikiquote!
