Hi, it’s probably been brought up before, but the statement “you can’t touch pre-tax retirement accounts without a penalty until 59.5” is incorrect. You can touch the traditional 401k accounts with a SEPP (substantially equal payment plan), and not pay the 10 percent penalty. You can also touch a Roth without the 10 penalty using the same strategy, although I understand you will pay taxes so you lose the Roth’s advantage. When I found this out, I stopped contributing to Roths because I wanted to retire early. Who knows if they will even live to age 59.5? So many people don’t!
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
