From Knowledge@Wharton: The Dow has hit its highest level in years, loan rates are at record lows and the U.S. economy appears to be gaining momentum. Even the housing market is starting to look inviting. But is this a real recovery — or a false start like last year’s? Wharton’s Jeremy Siegel and Scott Richard think the economy is showing signs of a true rebound, and predict that stocks should do well in the next 12 months. But bonds, they warn, are in dangerous waters, and economic growth will be in jeopardy if oil prices keep rising and the European credit crisis worsens.
