Newby TA question

Every stock and index I've looked at today has the 10 day MA crossing below the 30 day EMA in the last week or two.

Is that meaningful for the future, or is it just a reflection of recent market action?

 

Depends on who you ask. Seriously!

 

I just noticed that everything I look at seems to have a similar pattern. Is that unusual or a common occurrence when the indices take a hit like they have recently?

 

The stockmarket is correlated, and in selloffs like this everything has a correlation of 1.
