I'm sure that a person skilled can trade just about anything and do well..But a good trend helps too..Probably when the Fed gets finished with their printing press the dollar will be worth a lot less and gold and silver worth a lot more..But I just trade very few different stocks and have trouble keeping up with them..I invested more in realestate early on..So did well at that. Just sold my last commercial building 2 years ago. Looks like God was smiling on me..
