You need to analyze each instrument you are going to trade independantly. Each has its dynamics. In this case you will not make mistake. Some stocks are good to trade today, some are tomorrow.

 

If all the Dow stocks are green, the DJIA will be green as well.

 

Can you give an example? If all stocks are up the Dow is up because it's an index.
