Data from Bloomberg today shows just how profitable Apple’s recent buybacks have been with the company experiencing the highest returns of any company in over a decade. The buybacks, which were also the biggest ever since Bloomberg and S&P started tracking these numbers, came as Apple stock increased 77 percent over the last 15 months and 25 percent since its $18 billion buyback last year:

Those are the highest four-month returns among the 20 biggest quarterly repurchases by any company since 1998, according to data compiled by Bloomberg and Standard & Poor’s. S&P 500 constituents have spent $211 billion on their own stock this year amid concern the five-year bull market is prone to selloffs such as last week’s 2.7 percent retreat.

The report notes that other companies have been less successful with Microsoft experiencing a 16 percent increase in 2014 following its $3 billion buyback, while others including EBay and Boeing experienced shares falling. The average for the 100 largest buybacks being tracked by Bloomberg is a 5.5 percent increase this year.

Bloomberg adds that “the ratio of Apple’s per-share profit growth to its overall earnings has increased due to buybacks.” That includes an increase of 19.6 percent year-over-year as of last quarter compared to an increase in net income of 12.3 percent.
