I am buy and hold guy, never have guts and possibly the skills to successfully short any stock. Telsa is one of bubble stock now, but even if you are right, other people, especially those wall streets traders have to follow you with the same bet for you to make money. Little fish can’t fight the big guys. In 2005-2006 time many piggs here already knew about housing market cracks, but how many actually made housing related shorting profits when wall street still liked mortgage lenders? The real shorting opportunity happened in spring 2007 with public traded sub-prime mortgage lenders.
