fair. have you tried Dollar Cost Averaging on individual stocks before?The reality is that buying an ETF on any exchange is essentially the same as buying the 3 to 5 largest weighted stocks within that ETF. If an investor isn't making money on those individual stocks, it's unlikely he'll make money on the ETF too. Conversely, if someone can profit from buying an S&P 500 ETF, whether in the long or short term, he should also be able to profit from, e.g. THE "big-7" stocks too, given that these stocks are over 80% correlated (possibly even more than 90%) with the ETF. This principle applies to all index ETFs and their major component stocks. I think the key to survive is to create a well-defined trading or investing plan, which should include the following elements: 1) Your Objectives: Are you aiming for short-term quick profits, or long-term steady growth, or something in between? 2) Your Buy-Sell Style: Your objectives will determine whether you engage in short-term speculation, mid-term trading, or long-t (more...)

你根本就没读他说的东西。亚马逊第一说的是“牛市买什么亏什么”。 这样的问题不在于选择了什么品种来做投资或者交易。而是就在于更具体的细枝末节没有考虑过，没有做过plan，所以才会出现上涨了的标的买了也会赔钱。 不在于“选择买了什么”，无论长线投资还是短炒，你总会有一个买的动作， hold 的动作（经历涨跌心理情绪波动的过程），无论hold 多久也最终会有卖的动作。任何一个参与市场的人都躲不掉。 即使买卖ETF也不是买一下就完事了。

定投也不好使啊。最近还是亏

书太厚了。有没有一些读书心得，求分享

完全要坐享其成啊！Random Walk就是说短线来看，股价是随机漫步，不可预测； 定投：靠拉长投资周期来熨平经济周期的起伏； ETF：指数基金跟踪整体市场，规避个股风险。 我自己的补充：买入不同市场的ETF，比如：A股的ETF和SP500 ETF来对冲整个市场的风险。

刚听洪灏讲座的例子最近美股大跌，A股大涨，可是如果从2009年至今，A股还是3000，SP500涨了10倍。
