grey swan ？
这几天的Brexit使得black swan一词大家耳熟能详，今天偶尔在macmillan看到个grey swan ，但却在其他词典中没看到有收录的，再次印证macmillian在新词和phrase方面有些优势 本帖最后由 kyletruman 于 2016-6-27 00:36 编辑DEFINITION of 'Grey Swan'
An event that can be anticipated to a certain degree, but is considered unlikely to occur and may have a sizable impact on the valuation of a security or the health of the overall market if it does occur. A grey swan event is unlike a black swan event whose total impact is difficult to predict. Despite the possibility of determining the properties and potential impact of such an event, it is difficult to create precise calculations regarding the total impact.
BREAKING DOWN 'Grey Swan'
The term "black swan" was coined by Nassim Nicholas Taleb to describe the uncertainty and risk posed by unpredictable events. Grey swan events, which are derived from the black swan concept, may include earthquakes and even events like the Great Depression. While analysts can look at the impacts that similar events had across history, the exact extent of damage and risk cannot be calculated.

另外，Grey Swan还可在Financial Times Lexicon查得到。
我想问一下，grey swan 是不是可以直译成“灰天鹅”？ 灰天鹅比黑天鹅严重程度稍轻，看来还得再coin一个white swan才好进一步分类，哈哈 FT的这个财经词典真不错，这种解释要是能普及到一般大众词典就好了，详细易懂不容易忘。、
