That's a great strategy to go by! I decided to go 50/50 split because my company match isn't strictly towards a traditional or roth, but based off of a percentage of total contribution.
I like the approach you've taken to be more conservative of 25% above 52 week low. My stock investment is personal assets so I more look at it as "test" money for 401k money movement.
Agreed i tested my ideas in a regular stock portfolio to see how DGI worked. Then looked at how I could apply the same thinking inside the 401K. The hard part for me was finding out which funds paid routine distributions. Fidelity always tries to argue with me that it doesn't make a difference but the only way to get compounding to work is if you get extra units.
