Year-to-date, Oracle had earned a −1.53 percent return. During the same time period, Valero Energy earned 8.07 percent and McDonald's earned 0.70 percent. If you have a portfolio made up of 25 percent Oracle, 30 percent Valero Energy, and 45 percent McDonald's, what is your portfolio return?

The portfolio return is 2.35%

Explanation:

The portfolio return is the weighted average of the individual stock returns that form up the portfolio. The weightage of each stock is the investment in each stock as a percentage of total investment in the portfolio. The return of a three stock portfolio can be calculated using the following formula,

rP = rA * wA  +  rB * wB  +  rC * wC

Where,

rP = -1.53% * 0.25 + 8.07% * 0.3 + 0.7% * 0.45  

rP = 0.023535 or 2.3535% rounded off to 2.35%

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
