Thanks for sharing Freedom. Certainly many ways to skin a cat, I certainly respect that! Up until Friday, I have been 100% in preferreds and have been over 10% annually every year since 2013. Im down 6% this year now but was down 15% Wednesday morning, and I aint done fighting yet to get back to the plus side, lol...But it hasnt been from buy and hold, but as a modified version mirroring a bit your strategy which has involved a lot of flipping on disjointed price movements.
I will push back in a bit in defense of utilities as about 75% of my money has always been in utility preferrds so I have been able to generate returns there. But mostly because my personal opinion is they are as a general rule safer than banks. No Ute needed a bailout in 2008-09 while hundreds of banks including money centers did or they were dead.
After all it isnt called Utilityrupt, its called BANKrupt.
Only 3 utes have went bankrupt since Great Depression...Public Service New Hampshire (3 Mile Island) El Paso Electric (nuke building financing fiasco) and Pacific Gas and Electric (twice). So that generally is why utes pay less because of their business model.
But there has been some nice recent volatility that created some great plus 7% ute baby bonds I exploited.
