你应该是做了一点研究的, 看起来理由也是头头是道.
怕是还没有买过任何etf吧, 要不然也不至于这么初生牛犊.
你的几点理由都是没毛病的,
1) expense ratio对于小型投资者确实不高.. 你本身也赚不了几毛钱.
2) etf prospectus 里面自己都写了是target daily return, 长期return说不清楚..
3) 先跌再涨你可能没注意到的是..
凭什么你能上2倍, 3倍的的杠杆? 因为如果index 跌了50, 你杠杆是2倍的话, 你的钱就没了..
而另外一个没上杠杆的人, 钱还剩50.. 那现在index又涨回来了, 他赚回来了, 但你的是没有钱赚的..
贴一段upro的prospectus原话
```
Leverage Risk — The Fund obtains investment exposure in excess
of its assets in seeking to achieve its investment objective — a
form of leverage — and will lose more money in market
environments adverse to its daily objective than a similar fund
that does not employ such leverage. The use of such leverage
could result in the total loss of an investor’s investment. For
example, because the Fund includes amultiplier of three times
(3x) the Index, a single day movement in the Index approaching
33% at any point in the day could result in the total loss of a
shareholder’s investment if that movement is contrary to the
investment objective of the Fund, even if the Index subsequently
moves in an opposite direction, eliminating all or a
portion of the earlier movement. This would be the case with
any such single day movements in the Index, even if the Index
maintains a level greater than zero at all times.

换句话说, 你丢钱的速度应该比涨钱的速度快..
你的想法可以说很简单, 像简单的1比1的期货都是需要很多的margin才能维持的住仓位, 你这个x3的杠杆得需要多少margin..?
如果你对杠杆和日结很感兴趣的话,, 我(建议你上三和试试.. 啊不是) 是建议你上fx试试.. 毕竟有模拟账户. 但是一般这种bid-ask都太大了, 需要大波动率.
etf对你来说可能太无聊, 而且有一天你再看自己portfolio的时候就会发现不知道什么时候钱没了..
