I hear this everywhere. The thing is though bubbles while they may exist and easily go on for years. Look at the real estate bubble in the U.S prior 2007, and also the one i Australia. Australia "housing bubble" is only started to slow now, and thats after 10 years of solid year on year gains after the GFC. Its crazy.. All I know is if you stick with your last quote, you wont be too bitter if you hit or miss.
