To those that are not in retirement, or have not studied retirement withdrawal strategies they may not get it, but there is a big difference between accumulation phase strategies, as compared to withdrawal strategies. During accumulation you should be looking to maximize your total return, but during retirement you are looking more towards guaranteed income streams and while some may think that dividend streams are no guaranteed, for me I feel much safer putting my money in a diversified basket of companies that has been increasing their dividend for 30-50 years than in a bond fund that has been doing nothing but the opposite over at least the last 10 years. Most people think the bond fund guarantees them a secure income stream, however they seem to realize nothing about how the bond fund income is created or how insecure it really is. Sure it has a very low correlation to equity returns, which is part of the reason most support putting bonds into a portfolio - however, low correlation to equities does not an income stream make, as anyone investing in bonds in the recent past knows.
That is well put.
Most income portfolios I'm knowledgeable of hold no bonds, as their income is both small and fixed, which is generally not a good combination for a investment portfolio whose primary goal is reliable income that will meet household income requirements in retirement.
Dividend growth time periods is one of 3 selection criteria I and others who invest for reliable retirement income, will use. But, of course, it is not used in the ongoing monitoring of income securities once they've been added.
