????9月14日，瑞士聯(lián)合銀行（UBS）交易員奎庫(kù)?阿多博利因涉嫌欺詐及賬目造假被警方逮捕。

????每一位股票交易員都得面對(duì)“魔鬼交易”的巨大誘惑。授權(quán)交易就像一臺(tái)復(fù)雜的、合法的老虎機(jī)，經(jīng)常需要承擔(dān)巨大的風(fēng)險(xiǎn)。那么，公司如保證招募道德員工既能信心十足地進(jìn)行股票交易，又能抵擋住一擲千金進(jìn)行違規(guī)交易的誘惑呢？

????瑞銀交易員奎庫(kù)?阿多博利便是身處這種兩難境地的最新證明。9月15日，奎庫(kù)?阿多博利被捕，現(xiàn)在正面臨欺詐與賬目造假兩項(xiàng)指控。瑞銀稱，在過(guò)去三個(gè)月中，他一直私自進(jìn)行未經(jīng)授權(quán)的交易，給公司造成的損失高達(dá)23億美元。

????這起事件讓瑞銀顏面盡失，因?yàn)檫@家銀行最近剛剛徹查了其風(fēng)險(xiǎn)管理系統(tǒng)。但避免魔鬼交易并非易事。甫瀚咨詢公司（Protiviti）休斯頓辦事處的執(zhí)行董事戴維?約翰遜稱：“身處這個(gè)行業(yè)，沒有人會(huì)愚蠢到相信，以為這種事絕不會(huì)發(fā)生在自己身上。”

????雖然我們對(duì)瑞銀的安全防護(hù)措施知之不詳，但作為一家銀行，至少應(yīng)該遵循下面幾條最佳實(shí)踐。首先，銀行需要配備能夠警示可疑交易的安全防護(hù)系統(tǒng)；其次，經(jīng)理人需要審查下屬的交易活動(dòng)。每年或每隔一定時(shí)間，公司都應(yīng)進(jìn)行嚴(yán)格的內(nèi)部審計(jì)，查找出公司內(nèi)部哪些業(yè)務(wù)容易成為未授權(quán)交易的易發(fā)領(lǐng)域。公司甚至可以記錄交易員通過(guò)辦公室座機(jī)進(jìn)行的通話。

????但除了運(yùn)營(yíng)上的安全防護(hù)之外，防范魔鬼交易還涉及公司的招聘與企業(yè)文化。聰明的交易員也會(huì)受到強(qiáng)烈心理沖動(dòng)的驅(qū)使，做出錯(cuò)誤的決定，使公司陷入險(xiǎn)境。因此，經(jīng)理人需要做的就是創(chuàng)造一種環(huán)境來(lái)抵消這種沖動(dòng)。

????首先，這種工作需要員工有戰(zhàn)勝市場(chǎng)的堅(jiān)定信心。此外，約翰遜還認(rèn)為，要成為一名優(yōu)秀的交易員，還要讓外界對(duì)自己的能力產(chǎn)生有如神話般的崇拜?！斑@個(gè)行業(yè)的人更愿意進(jìn)行‘豪賭’，他們對(duì)此如魚得水?！边@樣的環(huán)境充滿了壓力和競(jìng)爭(zhēng)。

????UBS trader Kweku Adoboli was arrested on September 14 on charges of fraud and false accounting.

????For a trader playing the market, the temptation to "go rogue" is huge. Authorized trading is like a complicated, legal slot machine and requires the assumption of major risk on a regular basis. So, then, how do you fill your company with people who have the confidence to play the market but can also fight the temptation to throw good money after a bad trade?

????The latest example of this dilemma comes from UBS trader Kweku Adoboli, who was arrested on September 15 and is now facing charges of fraud and false accounting. UBS (UBS) says he covered up unauthorized trades over the past three months that lost the company $2.3 billion.

????This is particularly awkward for UBS as the bank recently overhauled its risk management system. Granted, preventing rogue trading is no easy task, "Nobody who's in this game would be foolish enough to believe that it couldn't happen to them," says David Johnson, managing director in consultancy firm Protiviti's Houston office.

????Without knowing the details of UBS' security measures, there are a couple of best practices banks should follow. Companies need to have security systems that flag suspicious trades, and on top of that, managers need to review trading activity. Every year or so, the company needs to do thorough internal audits to see which parts of their business may be vulnerable to unauthorized trading. Companies can even record conversations that traders have from their desk phones.

????But beyond operational security, preventing rogue trading is a question of hiring and corporate culture. Managers must create an environment that counteracts the powerful psychological forces that encourage smart traders to make bad decisions that put the company at risk.

????First off, the job selects for employees who believe they can beat the market. To be a good trader, you almost have to create a kind of mythology around your ability, says Johnson, "People who are in that business tend to be willing to place large bets, they're very comfortable with that," he says. The environment is high-pressure and competitive.
