What does all this mean? It means that women might need to take a slightly more aggressive path toward investing for their retirement. It also means that women need to start even earlier than men to start saving and investing. Other good tips are to set different goals than your husband, since your set of circumstances are different.
You might also want to have even more diversification in your portfolio than most so that if some of your investments go sour, you won't be left with nothing. It's also a good idea to stay on top of your investments. Reviewing them on a regular basis lets you know where your doing well and where you might need to make changes.
While it's unfortunate that a woman may need a completely different investing plan for retirement than her husband, the fact remains that there are forces conspiring against women in the workplace. But with the right strategy and the proper goals, everyone can enjoy a healthy and prosperous retirement.
