Citigroup is examining whether to move its equity research unit back into the investment bank, according to the Financial Times. The unit was moved to Smith Barney, the bank’s wealth management division, during former New York attorney general Eliot Spitzer’s investigations into tainted Wall Street research in 2002.

If executed, the research unit would report to Hamid Biglari, chief operating officer of the investment bank – and not to either sales and trading or corporate finance.
