贝恩资本为何要收购钻石电商 Blue Nile，如何理解 5 亿美元的交易价格？

新闻背景：Jeweler Blue Nile’s shares up 33% on $500 million private equity bid

Investors with Bain Capital and Bow Street will acquire jeweler Blue Nile for $500 million, the company said Monday.

The online jeweler will be acquired in an all-cash deal worth in which Blue Nile shareholders will get $40.75 for each share, a premium of about 34% over the company’s closing price on Friday, Nov. 4.

After the sale to an investor group made up of funds managed by Bain Capital and Bow Street, Blue Nile will become a privately-held company and will keep its Seattle headquarters.
