take a long position

ACA did so on an understanding it obtained from Goldman that Mr Paulson was to take a long position in the securities.

A CA同意这么做，但该公司当时从高盛得到的理解是，保尔森将做多这些证券。

For e. g., no matter what happens, if a stock hovering at 580 crosses the personally-set psychological level of 600, then the trader may assume a further upward move to take a long position.

例如，无论发生什么，一支股票在580左右徘徊，而交易员的心理位置是600，那么他就会进行多仓操作。

Certainly it is sensible to take the position, as do Mr. Dorfman and several others interviewed, that guilt is neither healthy, nor a motivation for long-term change.

多尔夫曼先生和其他几位受访者都认为愧疚感并不健康也不能成为长期改变的动力，这也是理智的看法。
