PMU,
Firstly, I did not imply, nor intend to imply that stock price movements do not follow a random walk.
There are many economists that agree that the Random Walk theory is not the only show in town, I would leave that debate to the experts.
I, like yourself, cannot predict the rise or fall in share prices, but what you can do is try and minimise your losses by trying to ascertain when would be the best time to buy into a market.
For example, anyone who would suggest buying into the ISEQ at the moment would need their head examined as it has been in freefall for the last year.
You do not need a degree in economics to know that you can afford to wait if you see the market falling.
You can use the ISEQ over the last week as proof if you need it that waiting in a falling market is worth the wait.
You can take a chance and hope it increases or you can give yourself the edge that your talking about and hold off for another week and see if it goes lower before deciding to buy in.

A bit cutting that remark, apart from the fact that any so called naive investor would have saved money if they had followed my advice.
