For me the problem is that you can’t have two masters. Who do you obey when the action that each demands is different. I think this is the crux of so many TA vs FA debates. For me both are excellent tools but I have never been able to mix them with any success.
I know plenty of people say you can combine, so you will have to work out for yourself what your truth is. Only having exposure when both agree might be one answer – but the market doesn’t seem to pay well for consensus, in my view you are likely to get needlessly whipsawed on your correct FA calls and miss some of the best TA signals – because speculative or highly leveraged / cyclical business that FA doesn’t lend itself to tend to give some of the best short/medium term trends when they go.
Thanks for the reply: What I meant to ask though, is that even if you make a fundamentally sound decision, surely there is merit in the idea of not staying invested in a share when sp dips significantly (even if the fundamentals are the same)? Assuming you're good enough of course, couldn't you sell out and then buy back in lower? Why wait till a purely fundamental change in the company if the share price is tanking anyway? I assume Tech/A would mention opportunity cost at this point: even if sp will eventually go up due to the solid fundamentals, isn't there a danger in waiting and riding it out, ups-and-downs, warts-and-all?
