Stocks pared losses after the Federal Reserve said it would reinvest proceeds from maturing mortgage-backed securities into the Treasury market.
The Dow Jones Industrial Average index nearly moved into positive territory after being down more than 100 before the Fed announcement. The blue-chip index was down just over 40 points after the statement after nearly moving into positive territory.
The boost in stocks after the Fed statement was releasedis a “relief rally,” as some market players were worried the Federal Reserve would stop investing in the Treasury market, said Dan Cook, Senior Market Analyst of Chicago-based brokerage firm IG Markets.
The Dow's biggest decliners were Intel , Alcoa and Microsoft . Merck and Procter & Gamble were among the few Dow stocks to advance.
The Federal Reserve held interest rates steady, as widely expected, and said that it planned to reinvest money from maturingmortgage securities into government debt and said economic growth would likely be "more modest" than previously expected.
Although the market bounced on the news, the Fed's move to reinvest mortgage proceeds is largely symbolic, according to London-based Capital Economics.
It's "designed to reassure the markets rather than boost the economy," the firm said in a research note.
“They are not really expanding what they have done previously,” said Cook of IG Markets.
But by taking this “small step,” and by acknowledging that the pace of the recovery has slowed, the Fed “leaves it on the table to re-engage the quantitative easing machine,” Cook said.
