Stocks retreated from their record highs on Monday, ahead of a frenetic week for markets. Investors are waiting to learn who the next head of the Federal Reserve will be, what several of the world's biggest central banks will decide on interest rates, and whether Apple and other big U.S. companies can keep piling their profits higher.

In the meantime, reports continued to show that the economy is strengthening and negotiations continued in Washington to cut income-tax rates. Amid the many cross currents, the S&P fell 8.24 points, or 0.3%, to 2,572.83 from its record set on Friday.

Investors expect President Donald Trump to announce his choice for the next chair of the Federal Reserve by the end of the week. The central bank has played a pivotal role in the economy's recovery from the Great Recession and the stock market's leap to record after record. Jerome "Jay" Powell, the leading candidate. The choice could have far-ranging effects on the markets, particularly if the new chair advocates a more aggressive policy in raising interest rates than Yellen has. Low interest rates have helped to push returns higher for bond funds, stocks and all kinds of other investments around the world. But pressure may be rising for the Fed to increase rates more quickly.

The yen was steady as the Bank of Japan maintained its key policy rate and target for the yield on 10-year government bonds, while showing concerns remain on the inflation outlook. The Bloomberg dollar index bounced from Monday’s drop and is on track for its best month since the election of Donald Trump as U.S. president. Ten as 10-year Treasury yields held below 2.4 %, with Trump’s choice to lead the Federal Reserve due by the end of the week.
