buy a dip

基本解释

I usually dip into a book before deciding whether to buy it.
我通常先瀏覽一本書然後才決定是否買它。
With fears of a double-dip recession rising, the Fed said it would buy Treasury debt using the proceeds from more than $150 billion of maturing mortgage debt that it owns.
由於對二次衰退的擔憂加劇，聯儲表示會使用其持有的超過1500億美元的到期觝押債券的收益來購買財政部債券。
The more times that dip is just 5% instead of 10%, the more investors will say “Buy” after a 5% drop, figuring that's all they're going to get in the way of an opportunity.
跌到5%而不是10%就止跌的次數越多，在下跌5%時叫“買”的投資者就越多，都覺著是撞到了一次機會。

The 8-day moving average stands at 1384, and testing that area and holding would be very bullish and provide a great entry to buy a dip.
