The U.S. government said that the economy grew at a pace of 3% in the fourth quarter, upwardly revised from its first estimate of 2.8%. Economists had thought the growth reading would stay unchanged, according to Thomson Reuters. The European Central Bank said it lent a total of €530 billion to 800 financial institutions in Europe as part of its second round of long-term refinancing. Economists had expected the banks to soak up a sum in the €500 billion ballpark. "Gold market participants are taking profit taking opportunity in conjunction with the Fed Chairman's comments regarding monetary policy," said Jeff Wright, senior research analyst with Global Hunter Securities. "With the recent run up in gold and silver; no fund manager wants to be the 'Bag-Holder' if a true correction back to the $1600 range occurs.... Our thesis of gradual appreciation is still intact but with periods of volatility in both gold and silver markets. I believe longer term investors will step in to support gold and silver if the sell off continues in the coming days." Jon Nadler, senior metals analyst with Kitco Metals, noted that in addition to the doubts surrounding a third round of quantitative easing in the U.S., European stimulus may also begin fading. "The ECB doled out more than $700 billion in loans to over 800 banks this morning in what may have been its last gesture of 'kindness' for a long time to come," said Nadler. "While many are calling the latest ECB operation a 'liquidity injection' that smacks of an outfight gift, we would be wise to note that the amounts in question are loans and that they have a three-year shelf-life."
