I was looking at an option chain today, for the first time. I'm not even thinking of options trading but would like to have some knowledge in looking at them to see a sentiment for some stock.

Could someone please point me in the right direction on what I see on this options chain? I'm not exactly sure what the 0.5 Call means with regards to the share price when the option may be exercised. thanks in advance
