Seminar on Stock Market.. .. really unknown subject

Last Monday I had a seminar on stock market. Actually everybody from our batch had to talk one subject on that day.It must be from financial domain, that is mandatory. Fortunatily or unfortunatily I selected stock market. My talk was utter flop. But we all got some primary knowledge to financial domain. Also I got some interest to play in Stock Market( in fututre only ) , eventhough I dont know how to look in stock ratings.
