In what may be our last quiz, ever, Tom turns the tables and puts Don in the hot seat with a Wall Street Journal high-school personal finance quiz—covering the Magnificent Seven, Roth IRAs, TIPS, efficient markets, yield curves, market risk, and dollar-cost averaging. Don does reasonably well, but not without protesting a dubious “debt avalanche” question and getting tangled up in a couple of accounting and risk terms. After the quiz-show nonsense, the guys tackle a listener question from Joseph in Pennsylvania: should your stock/bond allocation be based on a fixed percentage of your portfolio, or should it be driven by how many years of spending you want buffered in safer assets? Tom and Don explain why the answer depends on more than just income needs—it also depends on your emotional tolerance for volatility, your need for growth, and the role fixed income plays in helping you stay invested when markets get ugly.
