Paul,
As with Canslim and MR Oneil's ethos, the emphasis is on growth, sustained growth, sustanable growth, and of course the acceleration of such growth. Healthy stock selection cna still be achieved based on yeary + half yearly financial reports. I have done this myself. It takes a little extra work and you need to be a little more aware of the industry sector you are investing into. And of course your charting needs to be A1 with your entry and exit points.
In order to prove this viability to yourself, I suggest that you examine some of the IBD or champion canslim stocks based only on the criteria of information you have in the UK. Would you still have selected these winners based only on the UK criteria? Once again quarterly enrnings comparisons are a specific acceletory guide, and interpreted correctly, give you a better indication of the stock's past performance and potention to continue. Of course the market is still king and no amount of your belief will imply that the market reacts the same way. But this can still be achieved with Half yearly and End of Financial Year reports.
Hope this helps.
Hunya.
