I come from a fundamentalist approach in the choice of assets, doing analysis of multiples, analyzing strategy and competitors of companies and even doing valuation. The main change in my mindset was to understand that this approach is limited and that technical analysis can help me to improve my results, this being a complementary strategy to my primary fundamentalist choice. The biggest challenge today is whether or not to enter an operation and how to set my stop loss and when to finish the operation, making profit.
So you want to blend trend following with fundamentals?
Not a good idea. No evidence for such.
