The company also reported that as of Dec. 1, 2015, its assets under management climbed to $44.6 billion, a $200 million increase from Nov. 1, 2015. BAML added the company's stock to its U.S. 1 List, while giving it a buy rating and a $10 price target.

Now what: Och-Ziff's positive performance across its largest funds is welcomed by the market, which has punished the stock for declining AUM throughout 2015.

In the nine months ended Sep. 30, 2015, Och-Ziff's funds had collectively lost $1.7 billion in AUM due to outflows, primarily driven by nearly $4.2 billion of outflows from its multi-strategy funds. While one month doesn't make a trend, positive performance and AUM growth does help temper the view that Och-Ziff's AUM can only go down.
