Its not
something that would make out assurance that it would happen in the present or in the future. This is why it would be always ideal on making yourself that fully aware on things
so that you wont really be that disappointed if ever things go south.
As the volatility of the market will never change, I agree that just be aware of everything that happens in the market so that you're not putting something on your head that might even hurt you. Just think of these things as casually happening and if there are changes that will happen, they're all about the market's reaction to every situation that we're having. Things in the past few years might not be the same anymore but this is still the market that we used to live on and changes do come once in a while and we just have to like and live with it.
