I would NOT but it into blue chip stocks. You are betting on those companies not going down and your investments are far from being diversified. I would put it into a low cost index mutual fund where you are invested into ALL of the stocks out there. Far better in the long term than your idea...
Except that its not as dividend aristocrats/growers have consistently outperformed the market, there is tons of research on it and I can link you some if you wish. You can diversify away from equities if you wish. It may not be your cup of tea, but that doesnt make your statement true. You should read that linked article, and maybe some others on that site you'll be amazed at how little you know about how indexing works and that its already much more like what I suggested than what you think it is.
However, if you didnt need the money in the next 10+ years equities only is the time tested best return. Dont mistake volatility for risk, they are not the same. Companies like Exxon, Johnson and Johnson, etc (just an example and is not a statement on their current fair value) have been around and paying dividends since the late 1800s, through ww1, 1929, the depression, ww2, vietnam, oil embargo, korea, etc...and so on. There are a large number of companies that are alive and well and will outlive us all. If one was investing this much money it would behoove them to do some serious due diligence before placing any of the money into investments, and would think they could figure out and keep up with it regularly (10q/k's, annual reports, etc..) to know whether to get out if needed. Financial statements are not terribly difficult, you cant fake cash flow.
The other point is, not all companies have to make it. Heck make it 20 companies, a total bust you didnt see coming would be 5%. Over 30 years it would be rounding error. Your winners just have to outrun the one or two losers. The reasoning behind blue chips is safety, their wide competitive moats, dividends and proven shareholder accountability, and enduring nature.
Mman, nice to see another Joshua Kennon reader.
