Yes .. I am by nature a contrarian. However, I have found it only works well when supported by strong technical signals on the charts. A good recent example is EurUsd fx .. the whole world was saying buy its going to 1.30 1.40 1.50 ...... but, when we got close to 1.30, there was a strong daily downward move. This has led to a good correction so far. There are many other examples but remember that markets bubbles can always go further than you think (just look at house prices in UK recently!), So, wait for a good technical signal that will make the large players start to book profits, and go with it.
