80% of the funds were lost in an account that held 70% of the total funds, not 80% of the whole funds. This means that at least the remaining 30% was supposedly safe.

Now the 20% saved from the debacle represents a 14% of the total funds, which means FXE was actually down to (30+14 = ) 44% of the break even point when they were put on hold on 1st Sept.

Then we are told that they gained back a 7%. It’s not clear whether it is a 7% of the total funds or a 7% of the remaining funds. Either way, the best guess is that we are about half way of a full recovery.

As you correctly point out, this means a 200% gain or more needs to be made on the remaining funds to be back to the break even point. Still a long road…

They lost 80% of the main account… So that would mean they have 20% left.

Then they already regained 7% of the total INITIAL deposit. So they made a total of around 30% of what the remaining funds were.

Losing 80% is one thing, but gaining it back is another. You would have to actually gain 500% of what was left. I repeat, you’re not going to need to gain 80% in the few months that you’re asking, you’re going to need to double up the account, then double up again, then get another 25% of that account in order to be back to 100% of initial.
