NEW YORK: Disgruntled investors suing Wall Street firms over bad stock picks will soon get a windfall, as state regulators including New York Attorney-General Eliot Spitzer will likely release the findings of probes into Citigroup Inc and other banks by the end of the month. 

Officials for New York, Massachusetts and Washington are expected to present evidence on Citigroup’s Salomon Smith Barney unit, Morgan Stanley, Credit Suisse First Boston (CSFB) and US Bancorp unit Piper Jaffray before February, according to sources familiar with the matter.
