The Charts are extended and seem to be in need of a short term pullback, but as we said this weekend, the trend is absolutely up, and should be bought on weakness until the trend changes.
If it is that simple, why do you feel fear and hesitate? Why do some people think the market is going to crash?
Read and watch the above. It will scare you and force you to ask yourself why it makes sense to be in the market. The arguments are solid. There are always buyers and sellers in a market as huge as the US stock market.
I just stay on the correct side of the trend.
