????美式快餐發(fā)源企業(yè)、《財(cái)富》美國(guó)500強(qiáng)公司麥當(dāng)勞（McDonald's）)上周四宣布,，它將用200億美元進(jìn)行股票回購(gòu)和派發(fā)股息,，由此加入了過(guò)去18個(gè)月企業(yè)界的股票回購(gòu)浪潮。

????200億美元的數(shù)額會(huì)讓任何一位投資垂涎,，但這筆錢(qián)需要在回購(gòu)和派息之間進(jìn)行分配,。與2014年其他公司宣布的股票回購(gòu)相比，這筆錢(qián)只能算是零花錢(qián),。

????據(jù)Birinyi Associates的數(shù)據(jù),，今年迄今為止，各家公司已經(jīng)宣布了376項(xiàng)股票回購(gòu)計(jì)劃,，總額高達(dá)2,610億美元,。這個(gè)數(shù)字與2012年相比增長(zhǎng)了近72%，但與回購(gòu)創(chuàng)下紀(jì)錄的2013年相比,，略微有所回落,。

????回購(gòu)股票會(huì)幫助推高股價(jià)，很多分析師將標(biāo)準(zhǔn)普爾500（Standard & Poor's 500 index）創(chuàng)下多次歷史新高歸功于股票回購(gòu)的盛行,。

????但最近,，回購(gòu)勢(shì)頭開(kāi)始減弱,。跟蹤回購(gòu)比例最大的100家公司的標(biāo)準(zhǔn)普爾500回購(gòu)指數(shù)最近創(chuàng)下了自2012年年中以來(lái)的首次下跌。隨著股價(jià)連創(chuàng)新高,，股票回購(gòu)所產(chǎn)生的推動(dòng)作用消失,，公司投資較長(zhǎng)期項(xiàng)目或使用多余現(xiàn)金進(jìn)行收購(gòu)變得更有價(jià)值。

????據(jù)Birinyi收集的數(shù)據(jù),，下面是今年迄今已經(jīng)獲得授權(quán)的5大回購(gòu),。

1.蘋(píng)果公司

????《財(cái)富》美國(guó)500強(qiáng)公司蘋(píng)果（Apple）)已宣布，將從現(xiàn)金中拿出300億美元用于股票回購(gòu),。這個(gè)消息讓投資者很高興：股價(jià)暴漲,，甚至在消息發(fā)布一周后，這只股票相對(duì)于標(biāo)準(zhǔn)普爾指數(shù)在這7天上漲了12%,。蘋(píng)果有一項(xiàng)規(guī)模更大,、總額高達(dá)1300億美元的資本回報(bào)計(jì)劃，將一直延續(xù)到2015年,，而這些回購(gòu)就是這項(xiàng)計(jì)劃的一部分,。

2.富國(guó)銀行

????作為2014年資本計(jì)劃的一部分內(nèi)容，這家總部位于加州舊金山的銀行表示將把股票回購(gòu)量增加3.50億股,，總額達(dá)到近170億美元,。它還將派息提高約17%，達(dá)到了每股0.35美元,。

3.3M公司

????這家Post-it即時(shí)貼和思高（Scotch）膠帶制造商在2月份授權(quán)進(jìn)行120億美元的股票回購(gòu),，取代當(dāng)前75億美元的回購(gòu)計(jì)劃?！敦?cái)富》美國(guó)500強(qiáng)公司3M公司（3M） 遵循了去年末發(fā)表的聲明行動(dòng),。這項(xiàng)聲明稱(chēng)，公司在之后4年準(zhǔn)備投入100億美元用于收購(gòu),，最多將投入220億美元用于回購(gòu),。

4.美國(guó)電話電報(bào)公司

????《財(cái)富》美國(guó)500強(qiáng)公司美國(guó)電話電報(bào)公司（AT&T）)也于3月份批準(zhǔn)了回購(gòu)至多3億股股票的計(jì)劃，價(jià)值約105億美元,。這項(xiàng)回購(gòu)計(jì)劃是它過(guò)去三年中宣布的第四項(xiàng)回購(gòu)計(jì)劃,。這家公司自從2012年開(kāi)始股票回購(gòu)至今，總計(jì)已經(jīng)回購(gòu)了7.75億股的股票,。

5.卡特彼勒

????這家總部位于伊利諾伊州皮奧利亞的重型機(jī)械制造商于1月份批準(zhǔn)了100億美元的股票回購(gòu),，預(yù)計(jì)將在今年一季度回購(gòu)17億股股票，以完成先前75億美元的回購(gòu)計(jì)劃,。公司CEO道格?奧伯赫爾曼表示,，正在進(jìn)行的回購(gòu)是“我們的現(xiàn)金流創(chuàng)紀(jì)錄的結(jié)果”。（財(cái)富中文網(wǎng)）

????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.

????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.

????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.

????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.

????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.

????Here are the top 5 share repurchases authorized so far this year, according to data collected by Birinyi.

1. Apple

????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.

2. Wells Fargo

????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

????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.

4. AT&T

????AT&T (T, Fortune 500) approved a stock repurchase of up to 300 million shares worth about $10.5 billion in March. The buyback is the fourth initiative announced over the past three years. Since 2012, when the company started its stock buybacks, it has repurchased 775 million of its shares.

5. Caterpillar

????The Peoria, Ill.-based maker of heavy equipment authorized $10 billion in stock repurchases in January and expected to buy back $1.7 billion of its shares in the first quarter this year to complete its previous $7.5 billion repurchase initiative. The ongoing buybacks are "a result of our record cash flow," said CEO Doug Oberhelman.
