As the markets change, the value of each security in your portfolio will increase or decrease at a different rate of return; changing the overall weightings of your investments. Periodic reviews of your investment portfolio help keep your retirement strategy on track.
We're told we're supposed to save diligently for retirement during our working years, and socking away funds in a 401(k) is a great way to do so. If your employer offers a 401(k) plan, you can consider yourself lucky. And if that 401(k) comes with a Roth savings option, consider yourself even luckier.
