Scenario #6: Heidi has always been a real estate investor. She tells her financial planner that, because she is such an expert, its the only asset worth investing in. However, after a thorough assessment of Heidis actual performance, net of costs, her rate of return over time has been about 3.5%/yr on her real estate investing. This is not a bad return, but her planner shows her that diversifying her assets into other investments will not only earn her more return over the long-term, but also reduce her risk (because real estate will not always perform well, and other assets may-when real estate does not do so well). Heidi just cant believe that something she is so comfortable with could not be as optimal as what her planner is proposing. 1) What behavior/bias is present? 2) Why is this behavior detrimental? 3) What could have been done differently, or what could be done differently next time to avoid this result?
