hihi progamerCF,

I'm also new in stock trading, let's learn together... 

1)If you read the interim reports and annual reports, you can find a section where they calculate EPS for you..
for example TM's 2nd quarter report page 26 u can see:
Profit: 266M
Number of shares: 3,519.1M
EPS: 0.76
you can get past results either from KLSE or the respective company's website (if they update)

2)Yes, Just sum up 4quarters EPS to get the annual EPS.
If you just want Q2 EPS, then just use Q2-earning/Q2-number of shares.
Please refer to annual reports/interim reports, you can understand better from there.

3)By PE are u referring to Price-Earning ? If you are then i think it is based on each Public Listed Company and not the whole Industry...
I dont know that there is PE for the whole industry. If im not wrong usually they take past 4quarters earnings and divide by latest share price.. then u will get PER. Again, lets take TM as an example,

last years annual (4 quarters) EPS was 23.00cents
last traded at 3.05
PER: 3.05/0.23 = 13.26
