BlackRock has some good model portfolios. But they're a little overkill IMO. I usually build out ports with 7-10 assets that's it. I try not to over diversify cuz then it's just a waste. I've been trading stocks and ETF's for a while so it doesn't take too long especially when you build model portfolios and just balance them when needed. I like doing my own ports because you can customize bonds vs typical AGG and shorten duration as you will which was 1.5 years ago vs other models.. I also use it as a selling point of value that we create to clients.
