Is this 101 of speculating??

Stocks always rise if there is potential.
Earnings has little to do with the share price of most companies.
Sure DVT and ONE ended up failing, but those who bought in early made 150x there outlay if they sold at the right time, this is called trading.
I remember when DVT rose to 30c and everyone said it was ridiculous, not much later it was $6.
Then there are succesul companies like COH and CSL who now have earnings but once also started with only products but no earnings

If you dont know how to trade then dont touch speculative stocks, buy a basket of blue chips and forget about them.
But even blue chips go broke HIH ONE PAS etc etc

ENG could go to $5 or it could go to 0c, if anybody actually really knew they would bet their house on it as either a long or a short.
Its a punt like every trade, you buy what is either technically suitable or has the story you want and you use money management.

If anyones got a crystal ball not only about the share price but of the future of the company email me.
