buy a dip

基本解释

I usually dip into a book before deciding whether to buy it.
我通常先浏览一本书然后才决定是否买它。
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.
由于对二次衰退的担忧加剧，联储表示会使用其持有的超过1500亿美元的到期抵押债券的收益来购买财政部债券。
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%就止跌的次数越多，在下跌5%时叫“买”的投资者就越多，都觉着是撞到了一次机会。

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.
