Simply buy and hold QQQ will beat 95% people

However 95% people believe they can do better than QQQ

一八年卖悼所有烂股，全部买入大科技，几年来除了20年跑赢大盘SPY，其余几年回报率跟SPY相比差不多，也可能略好于SPY一点，应该是不如QQQ, 没有比较过。

每次财报季就会提心吊胆，最近一年心态好了点，管它涨还是跌呢，反正不能卖，卖了就耍交很多税。

后悔当初没有买指数基金。不知道现在红红火火的大科技股，还能火多久，二十多年前我刚入股市时的当红炸子鸡思科，英特尔，如今己眠然众人唉。

对绝大多数人，95%就是靠运气。但大家都努力做5%。

一个个牛气冲天

股票有时回调的挺猛的，看着盈利玩命缩水，也是很挑战心理的。

还早着呢。等福虎不兜售CVX而去买科技股的时候，就差不多啦。哈哈。

I thought about that idea too. 
 

but the problem is that the current top 10 won't be the top 10, 10 years later. Need to adjust it on quarterly basis. Then it becomes QQQ.

the good side is you can take loss on losing stocks for tax purposes 

不知道怎么做呀。谢谢展开讲讲

If you have a gain of 100K, you need to pay tax 30k. However if you don't sell, you don't pay the 30K. This 30K will keep making money in coming years. Eventually you still need to pay 30% tax, but you end up with more money left

这就是指数基金的优势

你讲的是股票波动幅度，不是真正的投资风险。对长期投资的影响，股票波动幅度趋于零。真正的风险是低回报率，没有赚到应该赚到的钱。

SPY里有很多夕阳产业，不可避免的会拉低，长期投资回报率。
