That is very true that the market is always right. The market itself has no emotion, just the traders who trade it do IMHO.... and all trades we do are against other traders. So?????
The market is always right, but it sure does change its mind a lot. The market is fickle, just like a lot of women I know.
'the market is always right...' sounds almost like a psychological variation of the 'efficient markets' mantra. it might be more accurate to say that the market always gets its way, whatever that is.
