McDonald's (MCD, Fortune 500), the all-American fast food Mecca, announced it would put $20 billion towards share repurchases and dividends Thursday, jumping on board the buyback trend that has boomed over the past 18 months.
美式快餐发源企业、《财富》美国500强公司麦当劳（McDonald's）)上周四宣布，它将用200亿美元进行股票回购和派发股息，由此加入了过去18个月企业界的股票回购浪潮。
A $20 billion number would make any investor salivate, but when divided between buybacks and dividends, it's pocket change compared to the share repurchase announcements other companies have made in 2014.
200亿美元的数额会让任何一位投资垂涎，但这笔钱需要在回购和派息之间进行分配。与2014年其他公司宣布的股票回购相比，这笔钱只能算是零花钱。
So far this year, companies have announced 376 share-repurchase initiatives for a total of $261 billion, according to data from Birinyi Associates. That's nearly 72% higher than 2012, though slightly lower when compared to the same period in 2013, which was a record year for buybacks.
据Birinyi Associates的数据，今年迄今为止，各家公司已经宣布了376项股票回购计划，总额高达2,610亿美元。这个数字与2012年相比增长了近72%，但与回购创下纪录的2013年相比，略微有所回落。
Repurchasing shares helps boost stock prices and many analysts credit the boom in stock repurchases for pushing the Standard & Poor's 500 index to record highs.
回购股票会帮助推高股价，很多分析师将标准普尔500（Standard & Poor's 500 index）创下多次历史新高归功于股票回购的盛行。
Recently, however, the buyback boom has started to fade. The Standard & Poor's 500 Buyback Index, which tracks the 100 companies with the largest share repurchase ratio, recently recorded its first quarterly decline since mid 2012. As stock prices reach record highs, the boost from share repurchases diminishes, making it more valuable for companies to invest in longer-term projects or use extra cash for acquisitions.
但最近，回购势头开始减弱。跟踪回购比例最大的100家公司的标准普尔500回购指数最近创下了自2012年年中以来的首次下跌。随着股价连创新高，股票回购所产生的推动作用消失，公司投资较长期项目或使用多余现金进行收购变得更有价值。
Here are the top 5 share repurchases authorized so far this year, according to data collected by Birinyi.
据Birinyi收集的数据，下面是今年迄今已经获得授权的5大回购。
1. Apple
1.苹果公司
Apple (AAPL, Fortune 500) announced that it would put $30 billion of its cash toward share repurchases. The news made investors happy: The stock popped, and even a week later was up 12% relative to the S&P over that same 7-day period. The buybacks were part of a larger $130 billion capital return program that the company said would extend through 2015.
《财富》美国500强公司苹果（Apple）)已宣布，将从现金中拿出300亿美元用于股票回购。这个消息让投资者很高兴：股价暴涨，甚至在消息发布一周后，这只股票相对于标准普尔指数在这7天上涨了12%。苹果有一项规模更大、总额高达1300亿美元的资本回报计划，将一直延续到2015年，而这些回购就是这项计划的一部分。
2. Wells Fargo
2.富国银行
As part of its 2014 capital plan, the San Francisco, Calif.-based bank said it would increase its buybacks by 350 million shares, or a total of almost $17 billion. It also boosted its dividend rate by about 17% to $0.35 a share.

3. 3M
3.3M公司
The maker of Post-it notes and Scotch tape authorized a $12 billion stock repurchase program in February, replacing its current $7.5 buyback program. 3M's (MMM, Fortune 500) move followed its announcement late last year that it intends to spend $10 billion on acquisitions and repurchase up to $22 billion of shares over the next four years.

The ongoing buybacks are "a result of our record cash flow," said CEO Doug Oberhelman.
