I will take my beta = 1.0 index fund all day, every day.
Anything else will likely lose over the long run.
My alpha is intentional financial planning, low fees, time in the market and tax efficiency.
The thing I love about index funds:
The single mom/art student/retired teacher can (and likely will) beat the traders on Wall Street by using index funds.
These powerful investment vehicles give us all access to build wealth.
