This is something from Forbes... Make no mistake about it: The summer rally is over. Not that it was much to speak of in the first place. It fizzled out in mid-July after a mere three weeks, and since then the market has slumped back to pre-rally levels.
What's holding back Wall Street? The answer is simple: interest rates. Bond yields jumped last week amid signs of burgeoning wage inflation. Higher bond yields sent the stock market lower in textbook fashion. And the bond market will continue to set the tone for stocks this week, with the crucial jobs report slated for release on Friday morning.
In the end, interest rates are the single most important determinant of stock prices. Sure, corporate earnings growth is great. But even good earnings can't sustain the market on their own. Over the past few years, valuation growth has outpaced earnings growth by far. Price to earnings ratios for the companies in the S&P 500 Index of large-cap stocks are now at their highest level in history.
Such sky-high valuations are only justifiable in a low-interest, steady-growth environment. And now interest rates are rising again with the anticipation of another rate hike from the Federal Reserve. Fed Chairman Alan Greenspan has indicated several times over the past few weeks that he has his finger on the rate trigger. The main culprit: creeping wage inflation.
For Greenspan and his cohorts on the Fed's Open Markets Committee, wage inflation is the greatest threat to stable economic growth. If the labor market gets too tight, the theory goes, wages will begin to rise too quickly. And wage inflation will soon spill over to consumer prices and eat away at economic growth.
Last week's employment cost index, which rose at its fastest pace in eight years, seemed to suggest that the labor shortage is finally beginning to translate into bigger paychecks. That shouldn't be a problem as long as productivity growth offsets the rise in labor costs. But the rise in labor costs couldn't have come at a worse time. The economy may finally begin to cool down, as last week's gross domestic product report for the second quarter suggested.
In other words, paychecks are beginning to balloon precisely at the point where productivity growth may be peaking.
Against this backdrop, it's no wonder that Wall Street is nervously awaiting this Friday's unemployment report. Greenspan said in his semiannual report to Congress last week that a further decline in the jobless rate from its recent range of 4.2% to 4.3% would be "one indication that inflation risks were rising."
Most analysts expect the unemployment rate to remain at around 4.3% in July, the same as it was in June. But at the same time, labor costs probably continued to rise as employers struggled to find skilled workers.
If productivity growth and labor costs are indeed parting ways, Greenspan will have little choice but to raise rates. And he'll have to act fast. It's too late to step on the brakes once you've driven off the cliff. What's more, fears of a Y2K-fueled economic downturn will prevent him from tightening monetary policy early next year.
With the next Fed meeting scheduled for Tuesday, August 24, Wall Street is facing four rocky weeks.
