'Don't Fight the Fed' Is Investors' Takeaway From Jackson Hole Conference

NEW YORK (TheStreet) -- Last Thursday, the S&P 500 index closed at a record high of 1,992.37. By Monday morning, the index touched the 2,000 mark. In between, investors heard from the Fed.

On Friday, Janet Yellen spoke at the annual Jackson Hole conference sponsored by the Federal Reserve Bank of Kansas City. Yellen's speech was much-anticipated as a possible guide to the thinking going on within the Board of Governors of the Federal Reserve System about the state of the economy and when -- not if -- the Fed will begin to raise short-term interest rates.

The S&P 500 stock index closed on Friday evening at 1,988.40, down 3.97 points for the day. Much discussion took place over the weekend about the meaning of the speech and what it meant for the future of Federal Reserve policy.

By Monday morning, one could reach the conclusion that Yellen had given a bravura performance of "Fed-speak" worthy of former Fed Chairs Paul Volcker and Alan Greenspan. That is, Yellen said a lot in her speech -- and gave away very little.

The highlight of Yellen's speech: "Our assessments of the degree of slack must be based on a wide range of variables and will requires difficult judgments about the cyclical and structural influences in the labor market.... While these assessments have always been imprecise and subject to revision, the task has become especially challenging in the aftermath of the Great Recession."

After a weekend trying to decipher statements like these, investors moved the S&P 500 upwards over 2,000, a new all-time record, soon after 10:00 a.m. Monday morning.

This has been the investor's mantra throughout this period of quantitative easing, as the stock market has almost continuously reached for new highs. And, the speech given by Yellen has apparently not changed anything.

Although the third edition of quantitative easing is ending in October, the general market consensus is that the Federal Reserve will not begin to raise short-term interest rates until the middle of 2015. Although there has been a lot more hawkish talk by some Fed officials about raising rates sooner in the press these days, Yellen and other officials still seem to be maintaining this view and have reinforced the general market consensus.
