Here's a challenge for traders .... [re the Nobel Prize for Economics]

(Reuters) - Three American scientists won the 2013 economics Nobel prize on Monday for research that has improved the forecasting of long term asset prices, a hot topic since the collapse of the U.S. housing market bubble prompted a global financial meltdown.

"There is no way to predict the price of stocks and bonds over the next few days or weeks," The Royal Swedish Academy of Sciences said in awarding the 8 million crown (781,885 thousand pounds) prize to Eugene Fama, Lars Peter Hansen and Robert Shiller.

"But it is quite possible to foresee the broad course of these prices over longer periods, such as the next three to five years. These findings ... were made and analyzed by this year's Laureates," the academy said.
