Could Stocks Actually Climb With Bond Yields
The conventional wisdom holds that rising interest rates are sure to snuff out the 4½-year-old bull market in stocks. Action in the markets on August 15 buttresses the argument. Standard & Poor’s 500-stock index tumbled 2.4% as the yield of the ten-year Treasury bond surged to as high as 2.82%, before finishing the day at 2.76%.

But now comes a fascinating report from the Leuthold Group, a Minneapolis-based investment research firm, that argues against the market’s recent action over the conventional wisdom. The report, written by Doug Ramsey, Leuthold’s chief investment officer, notes that the ten-year Treasury actually hit its record-low yield of 1.39% on July 24, 2012. From that date through August 14, the S&P 500 rose 29%, even though the ten-year Treasury climbed by 1.31 percentage points.
What’s more, the Leuthold study finds that stock prices and bond yields often rise in tandem, especially when yields start from a low base — which is precisely the case today. Since 1955, stock prices and bond yields have risen simultaneously about one-third of the time.
The more-recent numbers are just as surprising. From May 1 through August 14, the yield on ten-year Treasury bonds jumped from 1.63% to 2.70%. Over that same period, Standard & Poor’s 500-stock index gained 7.2%.
Still, stock investors shouldn’t get too complacent, because I think it’s a near certainty that bond yields will continue to rise. Higher yields can hurt stocks because they make fixed-income investments relatively more attractive and because they have the potential to slow down economic activity — the housing sector being one notably vulnerable sector.
How rising yields affect share prices depends in large measure on where yields are starting from. The lower the absolute yield on the ten-year Treasury, the more likely stock prices will rise along with yields. Ramsey finds that stock prices often rise along with bond yields except when the ten-year Treasury yield is 6% or higher. A 6% Treasury tends to be bad news for stocks. That doesn’t mean stocks always go up when yields rise but remain below 6%, but it means they often do. “Periods of jointly rising interest rates and stock prices have been much more common than widely recognized,” Ramsey writes.
Why would bond yields and stock prices rise in tandem? “Rising rates occur as business prospects improve,” says Ramsey. “Often the best time to buy stocks is when the economy is recovering from a recession and rates are rising.”
The situation today differs from what’s normally seen during the latter stages of a business expansion. At that point, prices are starting to rise, and the Federal Reserve Board, to quash inflation before it becomes too big a problem, starts to raise short-term interest rates. Both rising inflation and rising short-term rates can kill a bull market in stocks.
Rising yields on medium-maturity and long-term bonds also spell trouble. When the yield on ten-year Treasuries surpasses 6%, bonds provide major competition with stocks for investor dollars. The higher bond yields go, the more likely they are to drive stocks down.
But rising yields can be a plus for stocks. The current bull market, which began on March 10, 2009, started just ten days before the beginning of a 1.31- percentage-point spike in the ten-year Treasury’s yield that took place over less than two weeks. Frightened investors used Treasuries as a refuge during those awful days, and rising yields and stock prices were both early signals that things were finally getting better.
That’s hardly the only time rising rates have accompanied rising stock prices. Leuthold identifies 12 such instances, including the current one, since 1955, the period covered by the study. During these periods, the yield on the ten-year Treasury rose an average of 1.69 percentage points, and the S&P 500 gained an average of 35.3%.
What about today? It is different this time. The Federal Reserve has bought up trillions of dollars in Treasury securities with the professed goal of stimulating the economy. The incredibly low interest rates triggered by “quantitative easing” have encouraged hedge funds and other speculators to borrow huge amounts of money to invest in all kinds of risky assets, including U.S. stocks and emerging-markets stocks.
Now, of course, the Fed is talking about tapering back on and eventually ending quantitative easing. But even when quantitative easing ends, the Fed has pledged to keep short-term interest rates low for some time to come. Longer-term rates seem almost sure to rise, but if the Leuthold study is right, the bull market in stocks could continue.
Ramsey himself isn’t so sure. He notes that the ten-year Treasury yield has risen a full percentage point from its low — not far below the average for periods when bond yields and stock prices have risen together. “The current episode of jointly rising yields and stock prices is fairly mature,” he says. Maybe so. But bond yields still remain extremely low by historical standards, meaning stocks could well go higher.
