Well, your goals are admirable — but I think you’re starting a bit far down the road by trying to invest in specific industries. Do you work for a company that offers a retirement plan, a 40l(k) plan? If not, you might want to open your own plan — an Individual Retirement Account (IRA). You can do that by contacting Fidelity or Vanguard or TRowePrice. Each has a website and will give you information about opening a tax-deferred retirement plan (IRA). Then I would start by setting up a regular monthly investment automatically from your checking or saving account to go into the plan. You will be asked to choose a mutual fund to invest in. Pick the S&P 500 stock fund. It is a fund that includes the largest companies in America. And it will give you an idea of the ups and downs of the stock market. After doing that for 18 months, please write back and ask your question about specific stocks.
