????史蒂夫?鲍尔默日前已经启动了卸任进程，宣布将于明年9月从担任超过13年的微软（Microsoft）CEO职位上退下来。

????当然，这些年来绝非一帆风顺。但近日我看到一些针对鲍尔默的抨击，将他与微软市值下降联系在一起。我认为，这不公平。

????不错，2000年初鲍尔默接手微软时，这家公司市值约6,010亿美元。而在他可能退休的消息披露前，市值已降至2,700亿美元（消息披露至今，它的市值已增加了约200亿美元）。而且，微软的市值也被苹果（Apple）、谷歌（Google）这样的公司甩在了后边。

????但我们不妨来看看鲍尔默被任命为CEO时市值排在前十位的公司中，其他公司这些年来的市值表现。

1.微软：

当时：6,010亿美元

如今：2,700亿美元

变化：-55%

2.通用电气（General Electric）

当时：4,920亿美元

如今：2,420亿美元变化：-50.81%

3.思科系统（Cisco Systems）

当时：3,700亿美元

如今：1,285亿美元

变化：-65%

4.沃尔玛（Wal-Mart Stores）

当时：2,890亿美元

如今：2,410亿美元变化：-16.6%

5.英特尔（Intel Corp.）

当时：2,910亿美元

如今：1,120亿美元变化：-61.5%

6.埃克森美孚（Exxon Mobile）

当时：2,710亿美元

如今：3,855亿美元变化：+42.25%

7.IBM

当时：2,080亿美元

如今：2,030亿美元

变化：-2.4%

????Steve Ballmer today began his farewell tour, announcing that next September he will step down as CEO of Microsoft after more than 13 years in the position.

????To be sure, it has not been a smooth tenure. But today I've seen some potshots at Ballmer related to the company's market cap. And I think it's largely unfair.

????Yes, Microsoft was valued at around $601 billion when Ballmer took over in early 2000, compared to the $270 billion it was at before the news broke of his pending retirement (it's since gained about $20 billion or so). And yes, it has been lapped by such companies as Apple (AAPL) and Google (GOOG).

????But look at what's happened to the other companies in the top 10 for market cap when Ballmer was named CEO:

1. Microsoft (MSFT):

Then: $601 billion

Now: $270 billion

Change: -55%

2. General Electric (GE)

Then: $492 billion

Now: $242 billion

Change: -50.81%

3. Cisco Systems (CSCO)

Then: $370 billion

Now: $128.5 billion

Change: -65%

4. Wal-Mart Stores (WMT)

Then: $289 billion

Now: $241 billion

Change: -16.6%

5. Intel Corp. (INTC)

Then: $291 billion

Now: $112 billion

Change: -61.5%

6. Exxon Mobile (XOM)

Then: $271 billion

Now: $385.5 billion

Change: +42.25%
