Rock Springs has also had a long-time holding in McKesson Corporation (NYSE:MCK). The fund held a 139,750 share position at the end of 2014, valued at $29.01 million, its fifth-largest. McKesson Corporation (NYSE:MCK) was tabbed as a potential mover with high upside six months ago, when it was trading at just under $196. Shares are trading today at $226, and gained 9.09% during the first quarter. Billionaires Daniel S. Och and Larry Robbins had notable positions in McKesson Corporation (NYSE:MCK) at the end of 2014.

Thoratec Corporation (NASDAQ:THOR) had a big quarter, its shares getting a boost of 29.05%. Since a dismal earnings report on August 6, 2014 that sent shares plummeting the next trading day, Thoratec Corporation (NASDAQ:THOR) has rebounded big-time, posting gains of 84.56% over the past eight months, which has included two big earnings beats in a row. While sales of the company’s flagship HeartMate product line have flattened out, it scored double-digit revenue growth from its CentriMag line of blood pumps. Israel Englander had the largest position in Thoratec Corporation (NASDAQ:THOR) among funds in our database, with it standing at 1.91 million shares, and having been increased by 63% during the fourth quarter.

Another interesting and valuable pick of Rock Springs is Humana Inc (NYSE:HUM). We pegged Humana as the top potential takeover target six weeks ago, with the caveat that its soaring valuation made that prospect less and less likely by the day. The same is truer than ever today, as Humana Inc (NYSE:HUM) has added another $2.3 billion to its market cap since then, thanks in part to gains of over 24% during the first quarter. While Humana was slightly lower in Rock Springs’ portfolio at 19th, its position of 96,250 shares valued at $13.82 million was still 1.61% of the portfolio’s value, making its gains very worthwhile. Billionaires Larry Robbins and Stephen Mandel have much larger positions in Humana Inc (NYSE:HUM), though each carries slightly less exposure to the stock due to their enormous portfolios.
