Good stuff here from Barry Ritholtz who recently interviewed Ned Davis of Ned Davis Research. Davis provided Barry with his 4 basic traits of successful investors:
If you want to know if its worth your time to spend an hour with this legendary technician, consider what Ned calls the four basic traits of successful investors:
1. They look at objective indicators. Removing the emotions from the investing process, they focus on data instead of reacting to events;
2. They are Disciplined: The data drives decision making with pre-established rules. External factors do not influence them;
3. They have Flexibility: The best investors are open-minded to new ideas, or revisiting previous thoughts;
4. They are Risk adverse: Not always obvious to investors, it is a crucial part of successful investing.
