investing 50,000 USD now, after 220 days (one year) and compounding daily earnings with a 1.2 % per day -> 689,178 USD
not bad....
Yes, but that is not very realistic. First at all you can't compound, you'll need to purchase new shares with a new lock-in period. But I agree, the result could be similar after a years time. But more important is that Brandenburg confirmed to me that there are limitiations in the volume they are able to use for trading. Once they reach this volume - which also depends heavily on if and how much people repurchase after their shares are expiring - there might be times when no more shares are available to purchase.
IF they actually cap shares that would be a good thing.
IF NOT then we have a better indicator of where this is going. Problem is without auditing you have no idea if they've hit their arbitrage cap or the total assets they're working with.
