Dip, double dip, no dip, recovery, no recovery, inflation, deflation... All these macro stuff have nothing to do with trading financial markets unless you are a long term investor who holds on to his position for many months or years. If you monitor your trading/ investment on a weekly or daily basis, you go with the market and not things like inflation, deflation, economic growth, budget deficit, money supply, etc, all of which only have an impact on economy and markets over a longer period of time.
A bubble may be forming but it could be years before it finally bursts. In between there are many opportunities to buy and sell.
