You are the one getting it so wrong. On margin and apparently bad timing on your buy. Blame yourself. KORS could be one of the best stocks of the decade. All the people trying to "time" it with buying and selling will just mess up.. very few will win with that strategy.
If there is a market correction the stock will go down almost for sure. Some funds will dump the stock to cover losses on positions in other stocks.
I firmly believe that this company will go to $100 someday. But I will not be standing in the market's way. If I see another massive sell-off I will sell too and better buy later cheaper. The previous 2 weeks had so many distribution days that I start getting worried.
My advice don't fight against the market. Wait on the sidelines and jump in when the opportunity presents itself.
No stock can go up everyday, especially after we saw big gains 3 days in a row & today down over 200 points.
Best fundamentals in all retail, patience will be rewarded. However you may want to reconsider using margin...I think it's not such a great thing, borrow for a house or car, etc, yes but not for stocks IMHO.
