ignoring risk will bankrupt you
by staying in cash position at the peak will allow you to buy at 1444 while others loses 70% of their wealth
I agree with you that we cannot ignore risk.
However, your second statement is not really correct.
1. Staying cash at peak is not necessary a good thing. I'll short and make my money going down.
2. Market peak is not easy to determine. How do you know we are at the peak now? We could be just halfway up the ladder and there is still another 1k points to go. We don't know that, hence we cannot shout "wolf" everytime we see a shadow.
3. In trading and investing, we stay prepared for the crash, but we don't go around shouting doomsday everyday. It would be more helpful if you can teach others how to trade or invest in difficult times instead of trying to spread fear.
