越王问:"若不能卖在最高点,买在最低点,如何outperform the market? " 举两例

1)ETF OIH, 2022年以来在$300 左右swing N次,我跟着低买高抛N次,因为周期短,年化收益率很可观。我的一位同事选择常持,收益低微。

2)Exxon. 我在2020年低位吃进,到$90 因covered call 被买走。从此没再买Exxon 因为价格没有吸引力。但是资金也没有闲着,很快用于购买另一质高价廉的股票,收益也超过Exxon 后来的涨幅。

上面两种情况,pricing the market 的收益都高于长持。

当然如果遇上价值严重低估或真正的成长股(但价格不离谱),应该长期持有。我自己就有个别已持数年的股票,若股价没有显著高于其价值,打算持有十年不卖。

标普指数基金EPS年成长率仅3.5%,远远不够成长股标准(>10%),价位高了自然会抛掉。

原问题如下:

People who avoid the downsides are also the one who missed upsides. First, it is rare that people can sell at the very top. And it is also rare that people can buy at the very bottom. It is simple math, right? If you didn't sell at the very top nor buy at the very bottom, how do you out perform the market?
