However, being informed does not guarantee investment success immediately, but they are still prone to losses but mostly end up with their decisions getting paid off. That’s how an informed investor creates an advantage here.
That is right, it is not promising the investor to have a guaranteed success in investing as soon as possible. But the edge is there and being informed gives you the upperhand into the market and the assets/investments that you're trying to get into. The losses are going to be part of it and an informed investor understands that everyone has go through with that because no success person that never taken any loss. We can think of how much those millionaires and billionaires have lost before they have reached to the top. A billionaire lost millions, a millionaire lost thousands and so on.
