????9月14日，瑞士聯合銀行（UBS）交易員奎庫?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“魔鬼交易”的巨大誘惑。授權交易就像一臺復雜的、合法的老虎機，經常需要承擔巨大的風險。那么，公司如保證招募道德員工既能信心十足地進行股票交易，又能抵擋住一擲千金進行違規交易的誘惑呢？

????瑞銀交易員奎庫?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?阿多博利被捕，現在正面臨欺詐與賬目造假兩項指控。瑞銀稱，在過去三個月中，他一直私自進行未經授權的交易，給公司造成的損失高達23億美元。

????這起事件讓瑞銀顏面盡失，因為這家銀行最近剛剛徹查了其風險管理系統。但避免魔鬼交易并非易事。甫瀚咨詢公司（Protiviti）休斯頓辦事處的執行董事戴維?約翰遜稱：“身處這個行業，沒有人會愚蠢到相信，以為這種事絕不會發生在自己身上?！?/p>

????雖然我們對瑞銀的安全防護措施知之不詳，但作為一家銀行，至少應該遵循下面幾條最佳實踐。首先，銀行需要配備能夠警示可疑交易的安全防護系統；其次，經理人需要審查下屬的交易活動。每年或每隔一定時間，公司都應進行嚴格的內部審計，查找出公司內部哪些業務容易成為未授權交易的易發領域。公司甚至可以記錄交易員通過辦公室座機進行的通話。

????但除了運營上的安全防護之外，防范魔鬼交易還涉及公司的招聘與企業文化。聰明的交易員也會受到強烈心理沖動的驅使，做出錯誤的決定，使公司陷入險境。因此，經理人需要做的就是創造一種環境來抵消這種沖動。

????首先，這種工作需要員工有戰勝市場的堅定信心。此外，約翰遜還認為，要成為一名優秀的交易員，還要讓外界對自己的能力產生有如神話般的崇拜?！斑@個行業的人更愿意進行‘豪賭’，他們對此如魚得水?！边@樣的環境充滿了壓力和競爭。

????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.
