Behavioural Finance: Irrational Behaviour and Stock Market Investing

"You have great skill with your bow, but little control of your mind", said the master to his young archer.

This is also applicable in investing.  You can know everything about valuing companies, but it'll come to nothing if you can't apply it rationally when the heat is on.

Human behaviour is directed by a combination of evolutionary hardwiring and development programming, and you can see both in everything we do.

The trouble is that in stock market investing, a very recent phenomenon in human evolution, we haven't developed behaviours appropriate to it.

The usual range of other behaviour responses that we picked up in our early life are often completely inappropriate.

The greatest enemy in investing is actually yourself.  Beware of your irrational and yet human behaviour jeorpadising your investing.
