Think of cash as a financial asset that should be spread among six to eight investments. By Jeffrey R. Kosnett, Senior Editor From Kiplinger's Personal Finance, September 2014 The name of this column includes the word cash, but it seems like forever since I last discussed the green stuff. The reason is plain. The average money market fund pays 0.01%, and three-month Treasury bills yield 0.03%. Even if the Federal Reserve boosts short-term interest rates in 2015, as it is expected to do, the increases won’t induce a bank or money fund to pay enough to measurably impact your finances anytime soon.See Also: 9 Top Free Sites for Income Investors But cash has its virtues. Most important, it lets you sleep better. And everyone eventually needs some liquid currency, whether it’s to pay for a minor aggravation (say, to fix a fender bender) or a major one (the car was totaled). Or maybe you have a goal, such as paying a tuition bill or buying a second home, or you’d like to pounce on timely investment opportunities. I am not one of those curmudgeons who proclaim that “cash is trash” and exaggerate the opportunity costs of holding it (potential profits you didn’t make) by assuming that you’d have otherwise bought 5,000 shares of a long-shot stock that tripled in a year. By design, I keep 10% of my IRA in my broker’s cash account. When that proportion creeps up, which happened recently when a bond I owned matured, I flag the excess cash and reinvest it in a high-dividend stock and a couple of bond funds.

Let’s call 1% the Bernanke Line, a play on baseball’s Mendoza Line, the .200 batting average that separates awful hitters from the merely mediocre. (Non-pitchers who bat below .200 need to look for other lines of work; Google “Mendoza Line” for the back story.) Three times a year, we devote a page in our monthly newsletter Kiplinger’s Investing for Income to a portfolio called Juiced-Up Cash. One of the goals of this portfolio is to get you to think of cash as a financial asset that should be spread among six to eight different investments. Should interest rates eventually increase to the point that you can collect, say, 2.5% from an insured online bank account that requires no minimum deposit, doesn’t levy fees and gives you instant access to your money, you won’t need as much diversification. In the meantime, you need to squeeze the most juice out of your cash. Start by putting 20% of your cash stash in Fidelity Floating Rate High Income (symbol FFRHX, yield 2.9%), which invests in bank loans made to companies with below-average credit ratings. Put 10% in Wells Fargo Advantage Short-Term High Yield Bond (STHBX, 2.0%). Like the Fidelity fund, the Wells Fargo fund takes credit risk but offers some protection against rising interest rates (bond prices move in the opposite direction of rates). For foreign diversification, put another 10% in SPDR Barclays Short Term International Treasury Bond ETF (BWZ, 0.6%). For safety, put 15% into an online savings account and 15% in a one-year certificate of deposit. Then put 15% in a short-term bond mutual fund or exchange-traded fund and another 15% in an ultra-short bond fund or ETF. Choose among top-tier firms, such as Fidelity, Pimco and Vanguard, and the risk of mismanagement will be low. If you had invested $50,000 in this portfolio at the start of 2014, it would have generated $576 of income and grown in value to $50,172, for a total return of roughly 1.5%. If the second half is as good as the first, you’ll earn about 3% for the year. If you count just the income, you’d have earned 1.2% in the first half, putting you on pace for 2.4% for the year. That would put you well beyond the Bernanke Line. For income investors, that’s the equivalent of a home run nowadays.
