It  helps me to recall how the general market Event / Condition

impact upon each individual stock on that day.

This reflects the individual characteristic of each stock and its Price Reaction.

The next time, when a similar  event  happens,  i wish to use this Reference

to predict its  Price  Reaction  for that day.

This is my Theory and i want to see whether it works or not.

May be not 100%  on all stocks.

Hopefully, it works on a Few of  them.

This is what i call  EA (Event Analysis).

Like  Today,  most stocks fell, some significantly, some mildly. 

Some  stocks  rOse.  SMRT   COSCO  YANG  PST

Other  stocks  gOt  nO  Price Reaction. 

I try to relate  individual  stock's  Price Reaction to a particular Event.

In FX trading,  it depends significantly on EA.
