FBR Capital analyst Daniel Altscher added NorthStar Asset Management Group (NSAM) to his firm's Top Picks List following the recent pullback in shares. The analyst removed Northstar Realty (NRF) from the list. On the Q2 earnings call, management indicated they were working on an acquisition of a private company in the several hundred million dollar range, and such a deal could be announced over the next several weeks, Altscher tells investors in a research note. The "sweet spot" for a purchase price is in the range of $300M-$500M, the analyst believes. He keeps an Outperform rating on the stock with a $27 price target.
