Look who’s been dumping their Apple holdings by Philip Elmer-DeWitt @FortuneMagazine May 25, 2011, 3:15 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons The institutions that control 71% of the company’s stock moved a lot of shares last quarter Click to enlarge. Source: Business Insider Sammy the Walrus IV, who writes a Tumblr blog called AAPL Orchard and describes himself with a pseudo mathematical formula (Engineering and Finance background + Cynicism + Apple Knowledge = the Sammy Persona) seems to have got hold of some interesting Apple AAPL institutional shareholder information. He shared it with @SammyWalrusIV‘s 129 Twitter followers Tuesday in a series of cryptic tweets that Business Insider has largely verified with Bloomberg data (see chart). Sammy’s tweets: Who sold the most AAPL shares in 1Q11? Janus Capital (sold 3 million shares or 29% of its shares worth approx. $1 billion) Who bought the most AAPL shares in 1Q11? Capital Research bought 3.7 million shares increasing AAPL position by 51% or approx. $1.2 billion Goldman Sachs sold 61% of its AAPL shares in 1Q11 (approx $500 million). Apple’s largest shareholder (Fidelity) sold 4% of its AAPL shares in 1Q11. Out of Apple’s 10 largest owners, 4 reduced their holdings (all modestly) in 1Q11 Sammy’s take? Not many big AAPL sellers at the top of the ladder in 1Q11, just not many interested in buying more shares At the of the day…all that matters concerning AAPL shares are decided by its top 10 shareholders (collectively owning approx 25% of Apple) Note to SEC: During the quarter that Goldman Sachs reportedly sold 61% of its Apple shares at prices between $329 and $360, its sell-side Apple analyst was sending clients reports with a BUY rating and price target of $450.
