U.S. stocks slightly fell on Monday after the International Monetary Fund said it ready to assist Greece if asked. Greeks rejected the conditions of a rescue package from creditors on Sunday, but investors remained optimistic that a deal could be reached to prevent the country's exit from the euro zone. Stock markets globally fell, but analysts said the declines were less than expected due to expectations that the European Central Bank would act to limit any damage.
