There are obviously a great number of investments to choose from these days, and an investor quite often needs a substantial amount of money to build a solid, diversified portfolio. This capital requirement can be particularly challenging for young investors who are just starting out, as they may have minimal savings to invest.
However, exchange-traded funds can make it possible for younger investors to have a diversified portfolio with a relatively low investment threshold, according to "Shark Tank" panelist Kevin O'Leary (also known as Mr. Wonderful). ETFs have a number of features that make them ideal investment vehicles for the younger investor, said O'Leary, who is chairman of O'Shares Investments.
