If I have to pick one...

Fundamental analysis is most often used when determining the quality of long-term investments in a wide array of securities and markets, while technical analysis is used more in the review of short-term investment decisions such as the active trading of stocks.

For myself, I often look at the fundamental and overall macroeconomic landscape as the market outlook, and use chart to decide which stocks to buy or sell, and when to enter or exit.

I don't hesitate too long before deciding to enter the market. So for me, technical analysis is more important and useful than the fundamental. Looking forward to your opinions.
