Adage Capital Ups Stake in Constellium NV (CSTM); Apple Inc. (AAPL), Microsoft Corporation (MSFT) Among Top Picks

Adage Capital’s top pick heading into 2015 was Puma Biotechnology Inc (NYSE:PBYI), one of the biggest success stories among mid-cap stocks in 2014, as shares gained 82.27% on the year. July 23 was an historic day for the stock, as it gained nearly 300% in a single day following positive trial results for its breast cancer treatment, neratinib.

Puma Biotechnology Inc (NYSE:PBYI)

Adage, the largest shareholder of the company at the end of the second quarter of 2014 with 5.69 million shares, made over $1 billion that day. The leap also shot Puma Biotechnology Inc (NYSE:PBYI) from being its ninth-most valuable position to its most valuable by the end of third quarter, despite the stake remaining unchanged. The position remained flat in the fourth quarter, with the 5.69 million shares now worth $1.08 billion. Adage is still the largest shareholder of Puma Biotechnology Inc (NYSE:PBYI), followed by Samuel Isaly’s Orbimed Advisors having the next largest position among tracked funds with 250,900 shares.

Adage Capital’s next two picks need little introduction, as Apple Inc. (NASDAQ:AAPL) and Microsoft Corporation (NASDAQ:MSFT) rounded out the fund’s top three. The fund has been a longtime investor in both technology companies, which also happen to be among the top dividend stocks, having been invested in each of them for more than a decade. The fund has benefited not only from those dividends, but in the case of Apple, from shares that have greatly appreciated over that time.

At the end of 2014, Adage held 9.01 million shares of Apple Inc. (NASDAQ:AAPL) worth $994.24 million, down by 115,000 shares from the previous quarter, while in Microsoft Corporation (NASDAQ:MSFT) the fund held 12.38 million shares, worth $575.01 million, representing a decrease of 417,400 shares from the previous quarter. While Apple remained on the second spot, Microsoft moved up one position during the fourth quarter, surpassing Shire PLC (ADR) (NASDAQ:SHPG), in which Adage opened a large stake during the third quarter, but closed it during the fourth after a potential merger with AbbVie Inc (NYSE:ABBV) dissipated, causing shares to sink.
