New taxable portfolio

[navyasw02]

I started a Dividend Growth portfolio in my Roth, but now that I'm debt free I'm starting in my taxable account as well. I've got all the gold standards and first round draft picks in my Roth and now I'm looking at what stocks to put in my other one. When picking stocks, do most people treat them as a combined portfolio and avoid doubling up on some of the same stocks or do you view them as completely separate entities?
