不久前,大卫·格雷特曼把儿子安顿上床时感到浑身颤抖。在过去几年里,不断升值的股票价格令他成了一个百万富翁——至少纸面上如此,然而现在,借来的70多万美元被套牢,这让格雷特曼伤透了脑筋。市场突然滑坡,过去几个月,他已被迫借钱来弥补其保证金交易上不断增大的损失。这样的追缴保证金通知,加上低价抛售,让他损失了差不多100万美元,接近他总投资的80%。“当时我心里的感觉是,”格雷特曼回忆说,“得小心,我可是已经遭了大劫了。” Not long ago, David Gretman trembled when his son settled in bed. Over the past few years, rising stock valuations have made him a millionaire - at least on paper, but now, with more than $ 700,000 borrowed, it has put Grettman in jeopardy. The market has been in a sudden downturn, and in the past few months he has been forced to borrow money to make up for the escalating losses in his margin trading. This call for margin calls, combined with the cheap sell-off, cost him almost $ 1 million, close to 80% of his total investment. “My heart was feeling at the time,” Gretman recalled. “Be careful, but I’ve been robbed.”
