I am an amateur investor with almost five decades of experience. My first stock investment was made one Summer during undergrad school while I was employed as a "stock runner" for a small Wall Street firm where very kind people taught me and answered all my questions. I make NO CLAIMS of expertise beyond that of any other ordinary citizen.
I have been a dividend investor since my retirement in late 2003. I diversify by sector, domestic vs. international, and by cap size. I do not invest in stocks that don't pay dividends. I am risk averse and limit my investment in a single equity to 1% of my total assets or less. As a result of this 'rule', I have more than 100 equities in my portfolio.
