If you are using both technicals and fundamentals and trying to combine the two disciplines, there is no need to sweat over how much importance to give to which discipline. Idea should be to get clarity regarding the chart/company in question. Sometimes fundamental picture will be very clear, other times technical picture will be clear. In rare instances both fundamentals and technical picture will be clear, and in such instances one should work really hard, try to see if there are any strong investment arguments.
In broad market corrections, the sacrosanct technical levels will all be broken, and the feeling would be that technicals are not of much use. Best use of technicals is for entry and wherever possible , find out targets and take appropriate action.
