If it is virtual money, no problem to gain 50% in days time.
Use 100k buy FKLI contract, each contract margin roughly 5k, you can buy 20 contract.
Index surge 10 points, gain 9 points after deducting commission, Rm450 per contract x 20 = RM9k profit, already win 9% today.
So if bought last Monday at 1320, now gain 80 points = RM4k per contract, now you win Rm80k.

Actually virtual game has a bad effect as well.
While to win in those virtual game trading, you must punt those CWs, punt those goreng stock, penny stock that can gain you 50-100% in matter of days and month time only, as most competition concluded after a month or 2.
It is plain foolish to play the virtual game by buying blue chip stock, boring dividend stocks, as mostly you won't win in those competition.

While in reality, money is not easy to come by, a 100k can mean someone life-time saving, once lose, many not have second life to gain back the capital.
No capital in stock market, you are out.
Sound harsh, but this is the reality.

Hardly?
isn't
MBSB-WA just surge 50% for the last few day?
BIMB-CA surge nearly 50% for today and >100% over the last few days?
