眼看旗下對沖基金潘興廣場將連續第四年虧損，投資大佬比爾·阿克曼宣布，退出有關康寶萊的主動投資者多空大戰。

五年前，阿克曼首次披露持有10億美元康寶萊空頭頭寸，當時他指責康寶萊的業務是金字塔騙局。由此他跟主動投資者卡爾·伊坎對上了陣。當時伊坎是康寶萊最大的股東，阿克曼卻想做空這家公司。

然而，康寶萊的股價并未下跌，自阿克曼首次公開做空康寶萊之后還累計大漲95%。2017年11月，阿克曼的舉動顯示對做空康寶萊信心不足，因為他將理論上可能導致無限損失的康寶萊空倉轉為看跌期權。

最近，美國財經媒體CNBC報道，阿克曼已經清空做空康寶萊的倉位。

在此之前，由于阿克曼已退出或尚未獲得回報的一系列投資，潘興廣場到2017年已經連續三年錄得負回報。例如2017年年初他清倉的制藥企業Valeant持股，導致基金投資者虧了數十億美元。他重倉的美國食品業巨頭億滋國際2017年表現低迷，同年押注的墨西哥風味美國健康連鎖快餐企業Chipotle Mexican Grill至今還未有斬獲。

自阿克曼披露持股以來，Chipotle Mexican Grill因爆出食品安全危機股價大跌25%。

與此同時，據路透社報道，潘興廣場已裁掉近20%的員工，力爭重現往日輝煌。（財富中文網）

As his hedge fund Pershing Square heads into its fourth straight year in the red, investing titan Bill Ackman is calling it quits on one of the most high-profile activist battles on Wall Street: Herbalife.

Ackman first revealed a $1 billion short position against nutritional supplement firm Herbalife five years prior, dubbing the organization a pyramid scheme. (For more, read “The Siege of Herbalife” by Roger Parloff in the Sept. 15, 2015 issue of Fortune magazine.) That put him on the opposite side of the table from activist investor Carl Icahn, who turned into Herbalife’s largest shareholder even as Ackman mounted a campaign against the company.

But rather than falling, shares of Herbalife have rallied 95% since Ackman first revealed plans to bet against the company. Then in November of 2017, Ackman signaled that he was less confident in his call regarding Herbalife. The billionaire converted the short position, which in theory could lead to infinite losses for Ackman, to put options.

Then on Wednesday, CNBC reported that Ackman had unwound his bet against Herbalife.

That comes after Pershing Squares posted its third straight year of negative returns in 2017 due to a string of bets that Ackman has exited, or have either yet to pay off. Ackman for instance exited its stake in troubled pharmaceutical company Valeant in early 2017, costing his shareholders billions. His largest holding Mondelez languished last year, and Ackman’s bet on Chipotle Mexican Grill meanwhile has yet to pay off.

Since Ackman revealed a stake in the embattled quick-service restaurant, Chipotle shares have shed 25% following the return of its food safety crisis.

At the same time, Pershing Square has reportedly cut almost 20% of staff in a bid to turn the hedge fund back around to its glory days, Reuters reports.
