Hope springs eternal now that April showered us with a much-needed rally. Whether we are in a recession or not, the market is treating the economy gingerly while looking ahead six to nine months for signs of recovery. The Wall gets a bit less crowded as daily headline fears recede. Potential worries: The rebate checks are saved, not spent, and China’s economic growth drops into single digits. Fingers crossed that oil prices drop, the dollar firms and credit starts flowing. Sounds like a lot to wish for, but stranger things have happened — and we could end up with a surprise summer rally.
