The good part about the return is not just the actual return itself. Its also the time, stress and aggravation spent that is equally important. Lets say you spent a year of your life behind multiple monitors trading away. Lets say you then spent another part of your time after the market hours researching and finding more plays.
So you have given up a certain part of your life for the return.
When you get past 30, you value your time and mental health a lot more then you did when you were in your 20s.
I know some traders here spend their days behind multiple monitors in a small windowless room studying the price action at every waking moment. Then after market hours they spend more time in the same room behind more monitors looking for plays.
I would greatly accept the stressfree return of the DIA versus wasting my life away in front of monitors and then having to read BS on a messageboard from blood-shot eyed traders who spend their lives ruled by the monitors.
