An over agressive stock market can very well be a sign of things to come...and not good things. What investors there are out there are going to the only place left..and that is the stock market. And it's not necessarily a sign of a stronger economy or more hiring but of a weakness of the same.
In a "normal" market employment will be steady to growing and companies will be expanding, building, inventing, selling and designing along with adding more employees because of need.
This market is feeding off of itself, money on top of money with very little goods or services being provided as a basis for the increase in stock market activity.
Proceed at your own risk considering that all the wise investors taking profits now are also looking for signs of a fall. At that point they will take their money and run for the hills.
