Not that I am recommending hold or buy... and when I sell I sell quickly and won’t tell anyone first
but...
If you don’t want to endure one quarter of weakness due to whatever reason, for example Amazon getting aggressive in certain category temporarily like last year, if you don’t see it able to grow at a high rate over a number of years despite the fluctuations quarter to quarter, then you should take profits at every peak. Nothing wrong with that at all.
It seems to me that winter has come and the next round of tree shaking wind will only be stronger so if one is leaning toward sell now one should just sell out instead of waiting until it touch base with 200 day EMA for example. Absolutely nothing wrong with that. I have sold some of everything post HY reporting myself in preparation for this winter.
