Your asset allocation should represent your appetite for risk. If you're 65 years old and ready to retire, your asset allocation should look different to someone who's 25 years old who is ready to make good dough for another 40 years.
In other words, none of the news should bother anyone as long as their asset allocation is appropriate. It has been that way forever and it will be that way forever. Anything else is market timing or gambling.
If you are 65 and hold 100% Harley Davidson and Maple syrup stocks right now. Yeah, I suggest you change that.
But everyone is entitled to do what ever they want to do with THEIR money.
