In the professional world, one of the key concepts is diversification. Harry Markowitz is a Nobel prize winning economist and one of his major discoveries was that adding new asset classes can dramatically alter the overall risk profile of a portfolio. His finding was that a portfolio that contained very low risk assets would normally benefit from lower volatility and higher returns if a higher risk asset was added. This is due to the likely lack of correlation between high and low risk asset classes.

History shows that investing in stocks is one of the most efficient ways to build wealth over time. Nearly every member of the Forbes 400 list of wealthiest Americans got there because they own a large block of shares in a public or private corporation. Learning to invest wisely and with patience over a lifetime can yield a portfolio far outpacing the most modest income.

If you have a job, your employer may offer a 401k or 403b retirement plan as part of your benefits package. These accounts invest your money for retirement, but your investment options are limited to the choices provided by your employer and plan provider. If your employer doesn't offer a retirement plan, you can open an IRA on your own with your bank or brokerage company.
Finally, you’re going to be looking for catalysts or roadblocks to growth for each company. This means looking in the financial news, reading analyst reports and management presentations. By this time in the process, maybe you’re only looking at four to six companies in a sector so this level of deep research won’t take more than a couple of hours.

You’ll come across an overwhelming amount of information as you screen potential business partners. But it’s easier to home in on the right stuff when wearing a “business buyer” hat. You want to know how this company operates, its place in the overall industry, its competitors, its long-term prospects and whether it brings something new to the portfolio of businesses you already own.
