Overnight, there was breaking news that the $73 billion market capitalization behemoth, Costco Wholesale Corp. ( COST ), is suing Acushnet Holdings Corp. ( NYSE: GOLF ), the owner of the popular Titleist golf balls, equipment, apparel, as well as owner of FootJoy. This news caused me to take another look at shares of GOLF. In late December, I too read about the cult-like status for Kirkland brand golf balls in the WSJ (see Suzanne Kapner's 12/14/16 piece ). However, fellow SA contributor Colin Tedards beat me to the punch and wrote a nice Seeking Alpha Pro Article, on December 22, 2016, on the pricing disruption that this may cause Acushnet and its lucrative golf ball business measure in both market share and profits. However, given the ratcheted up stakes, as we learned yesterday that Acushnet legal team sent a nasty letter to Costco, this is a negative for shares of GOLF.
