I think just be prudent and not put too much into it. Wait for the collapse, meanwhile keeping your money safe. People have been calling this a bubble for the past few months.
Other central banks are doing the same - everyone is trying to weaken their currency against teh dollar, so a lot of printed money is being sold for dollars and then parked in American stocks.
This is why people are starting to lose trust in fiat. Governments can just manipulate their currencies, in ways that can be complicated for many people to understand yet those same people pay the price when it all collapse.
