I NEVER short anything.
Well ... depends on how you interpret that.
If I don't like the way the market is acting, or I have some totally unrelated things I have to do which will require most of my attention then I go from long-stock to all-cash. Been that way for over two weeks now -- maybe three.
So there you go, I'm not shorting squat -- and I am definitely not losing money (if you don't account for inflation).
I also do not like the current state of the Yield Curve. It is now highly inverted, and it is easy to interpret that as a signal of a lot of money flowing into high-return short-term bonds (or just into cash).
