It could be done but one Port would have to play the OW's one day & the other Port would have to play them another day. No Same-Day Trades.
The intrinsic problem with this Idea is that there are frequent turn-arounds in OW's (from LONG to SHORT & vice-versa). When this happens (especially on a Friday), one Port would do fine & the other Port would get Scorched on the turn-around.
Basically, if you proceeded with this Idea, you would be making Significant Sacrifices with the Big Port. Or wasting your time with the OW Port if it is the one making the Sacrifices. Or one Port could make the Sacrifices one Week & the other Port would make the Sacrifices the Next Week. Inevitably, there will have to be LOTS of Sacrifices made.
Better Ideas would be a YTD Port (No Same-Day Trades still apply) where you would be Sacrificing the Big Port, a StarBonds Port (No Same-Day Trades still apply) or a NEGATIVE Port (No Same-Day-Trades still apply).
Another Better Idea would be to run a MovieFund. Good Managers are needed there. For example, the Fund Manager for (PARAX) has run that MovieFund right into the ground. There are also some other MovieFunds that could be started or re-started,
Best Wishes.
