While I agree KORS is a good growing company, I suspect its accounting practice is too aggressive. One concern is while KORS has its founder as an American and its majority of business in the US, it is a Hang Kong company, treated as a foreign issuer in NYSE. As a result, KORS faces far less regulatory filing requirements. All previous KORS filings have much less transparency than many other US competitors.
This is just my simple speculation. I have dot done a thorough analysis on KORS yet. One reason is there are just not enough public data about KORS.
