Since leaving Morgan Stanley last year after a power struggle, Joseph Perella has been draining his old company of some of its top talent seven at last count for his new venture. But a big fish just got away. Jon Anda, who joined Perella as a co-founder of the still-unnamed investment boutique, has returned to Morgan Stanley. The firm couldnt be happier, the New York Times says, adding that the sudden move may indicate that Perella is having a tough time attracting the staff he wants, but could also be a sign that MS Chief Executive John Mack is making some progress in his mission to restore Morgan Stanley to its past glory. The move back also is good for Anda, whose experience in capital markets, says The Times, is more suited to a big firm than a boutique.
