Most of us don't know enough to duplicate your success. My money is in index funds because I know from experience that I'm bad at picking stocks. Most of the people I've talked to don't know that much about it. I don't think becoming an expert investor is that easy.
One of my points is that there is NO SUCH THING as an expert investor. Let me give you two examples why I say that.
Bristol Myers, the drug company, at present, has 3 analysts giving it a strong buy recommendation while one analyst gives it a strong sell recommendation. Additionally, Caterpillar, the large equipment manufacturer, similarly has 7 analysts recommending buying the stock while 2 analysts say sell it if you got it. They all are looking at the same data in order to make their recommendations. If they were so called experts, looking at the same data, then they should all come to the same conclusion. My point is that several of those analysts above are DEAD WRONG since they have opposite conclusions.
I think the same thing can be said of the writer of the AARP article. AARP is doing a disservice printing that article because their members could be missing out on individual stocks that could be to their advantage to own.
One expert I do listen to, and emulate, is Warren Buffett. He, over the years, has accumulated a portfolio of excellent companies, held those stocks for decades, and has had a fortune result from holding those solid companies. He stays away from speculative stocks.
My 400% increase is not due to some special knowledge. It is due to selecting stocks of well known, solid organizations that, over a long time horizon, will increase in value.
Index funds, Mutual funds, and ETF's lets someone else, supposedly experts, make the choice for you and I already have made myself clear as to the subject of experts.
