I like your conviction Bear. But off course companies that have no earnings (profit), could “potentially” go to zero 
Normally, I’d be doubling down here, like you are. But I’m holding back for now because there is just too much uncertainty and instability in the market. There is the China trade war, new EU tariffs, USMCA ratification, Brexit, EU recession, Turkey/Syria, impeachment inquiry, softening consumer confidence, very weak manufacturing data. We’re also into the 4th quarter when a lot of institutional investors are locking in profits and rebalancing to polish their numbers for the year.
I’m still keeping a larger than usual cash position for now, which I started building in July, because I’m uncomfortable with this set of macro conditions. But who knows, when these things bounce back they will probably snap back fast, and I’ll regret not taking advantage. But for now I can sleep a little easier.
