Everyone talks about Warren Buffett and to a lesser extent his mentor Benjamin Graham. Graham describes in one of his books what he considers to be investment grade stocks and SDL and probably the majority of stocks on the ASX don't fit the definition, they are speculative.

Other books go to great length to tell investors / speculators to use self-discipline, set targets, use stop loss orders etc.

Pythagoras is lecturing us in relation to his/her hindsight. Yes at the time his/her SDL was worth 60c he/she was expecting it to go to $1. He/she had no target price or did not stick to it, or it wasn't achieved.

Nobody knows what is going to happen, we can only speculate. Most people who own SDL probably do so because it passes one of Graham's characteristics of an investment grade stock, its resource. Other than that it is speculative and a gamble.

Pythagoras thanks for the advice but have already been there and regretted it a number of times before. Also if your thinking about it all the time, maybe you should get some professional help, it doesn't sound good.

IMO etc
