It is possible. Example. Imagine you bought an OTM call on Bear the friday before it sank, and put all account in it because you thought you had a rocksolid bottom. The next trading day, it went to $3 or so down from 30 dollars something. You now have a ton of calls with market: Bid:0.0, Ask:0.05, and no volume. No one is buying. Unless Bear goes to the moon, the portfolio value is practically equal to zero with a clock ticking fast even for those holding leaps.
If I recall it correctly, you started with a 3K account Therefore you made 10% return, but you risked 30% of your account. Just to break even you will need a be right 3 times on four trial (an average of 75%). To be profitable you will need more than 75%.
In addition the above is an arithmetic average. The most likely result is the geometric average. ((0.70)*(1.10)^30)^(1/4).
