Still look look see see, a lot of stocks is still overvalue... wait for more discount first. 

The simplest way is to look generally at PE, DY and PBV values. Also look at future growth, higher growth warrants higher PE.

My own ultra-simple layman formula for reasonable PE = (Future growth% + DY%)

For dividend stocks you need to see DY%, Payout ratio & dividend growth%. Generally DY>5% (~2x FD) with payout ratio of <50% (sustainable) and dividend growth >5% (chase inflation) is a good bet.

However that's my layman 555 formula, other investors might have different ideas...
