By 2016? It's still a long way off, like 4 years. We TZAers have come in way too early to the real party. It would be better to just have a monthly TZA accumulation plan, until 2016 when the real party starts, according to Kiyosaki in 2002.
You have to be nuts. buying this scam because you think the market may drop in 2016? If the market is flat until then TZA will lose over 95%. But hey, more power to you if you have money you don't mind just throwing away.
