A former analyst at Merrill Lynch & Co. Inc. who pleaded guilty to insider trading was sentenced Friday to three years and a month in prison for his part in a scheme that involved gabby investment bankers and leaked copies of a market-moving magazine.

Stanislav Shpigelman, 24, of Brooklyn, N.Y., had admitted tipping other participants who made more than $6.7 million from October 2004 to August 2005. At the time, he worked in Merrill Lynch’s mergers and acquisitions division.

In a plea deal he signed with prosecutors, Shpigelman admitted to a single count of conspiracy to commit insider trading in return for a recommendation that he serve from three to four years in prison.
