主题：准备买几种美国的ETF，请高手指点 -- 一直在混
家园 准备买几种美国的ETF，请高手指点 本人菜鸟一个，上周才刚刚下海：）
看中了以下几个：
URE 房地产
UYG 金融
USO 石油
还有SKF，也是金融，最近一年大起大落，抱着小赌怡情的想法准备买一点
我的标准很业余，基本只看最高点和现在价格的比值，越高说明潜力越大：）
家园 【原创】must understand leverage LZ must understand the leverage ETF first before touch them. Among the 4 ETF mentioned in your original post, 3 (URE, UYG and SKF) are 2x leveraged ETF. They are designed to track underlying daily index DAILY by either 2 or -2 times. For instance, UYG is 2x of XLF and SKF is -2x of SKF DAILY. I could not emphasize more the word "DAILY". Imagine you have both SKF and UGY shares, $10,000 worth each. What would happen if XLF up and down 2% every day for 200 days. The underlying ETF, ie. XLF is at the same price, but both SKF and UGY decrease to $8500. ([0.96*1.04]^100=0.85). So one should not hold leverage ETF for long time unless he/she knows the underlying ETF will go straight up. Indeed, shorting both highly leveraged ETF is a good way to make profit. For instance, short both FAZ and FAS.
家园 手上持有VNQ（房地产）若干 一周从37涨到39，如果一直保持这样的势头多好啊：）
不过又和URE比一下，潜力似乎远远不如啊，是否该换一下？
Ultra ProShare不知什么来头，另外几种ETF也和同类比价格要低不少
家园 UNG 天然气 家园 赌博啊？ 好坏不知道，不过这样的购买原因，就像是赌博嘛。记得以前有报导过USO的问题，大致是太大了被人frontrun:

家园 不是高手，也不推荐 假如你对美股整体有看法的话，可选择SPY，跟踪斯坦普500指数。
对科技板有看法的话，可选择QQQQ，跟踪纳斯达克100指数。
对金融板有看法的话，XLF应该比较典型。
据我所知，USO应该是跟油价同步的。
选择ETF，可以先大致了解一下该ETF包括了什么以及比重，比如XLF包括：

Jpmorgan Chase & Co 12.45% 20,462,616
Bank Of America Corporation 11.02% 45,321,228
