正股和deep in money short put是主力部队；
deep out of money long call是空降兵/敌后小分队，没了就没了，但是偶尔可以有机会实施个斩首行动啥的；
ATM short put/call基本属于前线，他们的作用就是来来回回地砍；
deep out of money long put类似于埋雷分队，一般情况下用不上，但敌人（对手方）要是穷追不舍就让他们喝一壶。
KraftHeinz -16% amid SEC probe, $15.4B in Q4 writedowns
Feb. 21, 2019 5:56 PM ET|About: The Kraft Heinz Company (KHC)|By: Carl Surran, SA News Editor
Kraft Heinz (NASDAQ:KHC) -16.3% after-hours as the company wrote off $15.4B related to previous acquisitions and said it received an SEC subpoena as part of an investigation into the company's accounting policies.
KHC says it recorded a $25M “increase to costs of products sold” as a result on an internal investigation with the help of an outside lawyer.
Much of KHC's unadjusted Q4 loss was due to the impairment charges "to lower the carrying amount of goodwill in certain reporting units, primarily U.S. Refrigerated and Canada Retail, and certain intangible assets, primarily the Kraft and Oscar Mayer trademarks."
The writedown of the big-name brands is "a striking acknowledgment that changing consumer tastes have destroyed the value of some of the company’s key assets," Bloomberg reports, adding that the disappointing results may raise the pressure to grow via acquisitions.
Update: KHC says in its earnings conference call that it is cutting its quarterly dividend by 36% to $0.40/share. 。
