I have held continuously many blue chip and tech stocks such as AAPL NFLX GOOG/GOOGL AMZN going back as far as 2006-2007. Before that, I mostly traded, although I did hold some stocks continuously during the glory days of the late 1990s.

Today, in addition to these long term holds, I trade, sometimes day, other times position (medium term), extra shares of usually the following stocks
AMZN TSLA GOOGL CMG NFLX
on top of the long term shares that I hold.
