After 14 years with a Finance Degree... I've learnt... Nothing makes sense.
In the long term, things make sense.
Example. If interest rates are low, prices of things tend to end up higher in a middle to long term.
In the short term, however, anything goes. Markets could go up, or down, there's no real rationale behind it, besides traders having their fun.
If Governments print money to inject into the market. Their currencies WILL devalue. This is what happened to the USD and EUR. HOWEVER, no one knows if the Governments will remove the injected funds from the economy in the future to raise the value of their currency again.
Markets may crash... You may wait for a good opportunity to buy. HOWEVER, Governments can step in and prevent the crash, by bailouts, injecting more funds, etc...
So... you COULD be right... but you could also lose money or lose an opportunity.
The problem is uncertainty...
