Analysts are warning many investors about attempting to call a bottom, as yesterday’s stock rally has hopes up. Markets and exchange traded funds (ETFs) need more than one good day for a recovery.

Stocks are modestly higher as investors try to turn Wall Street’s best performance this year into a two-day advance, says Sars Lepro for the Associated Press. Although the financial stocks that led the rally are keeping their gains, analysts caution that the market is still under water. Investors bought stocks furiously Tuesday on news that Citigroup Inc. was operating at a profit for the first two months of 2009.

World markets are also enjoying the news regarding Citigroup (C) as Asian markets rallied along with European markets taking modest gains. Jeremiah Marquez for Associated Press reports that the relief was likely to be temporary as the economic slump continued to ravage Asia’s export-driven nations. The fact that Citigroup turned a profit does not help the fact that many large economies are still suffering a slowdown.
