Duration Principles Can Apply to Stocks?

I’m repeating last month’s lesson about duration principle investing, as it may be applied to stocks.(See yesterday's blog on bonds.)

I have in the past discussed important rules behind bond duration, which include the need to reinvest the periodic dividends of funds in which the bonds are held.

There is a somewhat similar principle with stocks that have an assured high income.

REITs are one example: If high periodic returns are reinvested in the same entity, you get a similar effect. Such purchases help mitigate risk and reduce average costs of long-term holdings; hit-and-miss market-timing is avoided. (See the Earl J.Weinreb NewsHole® comments and @BusinesNewshole at Twitter.)
