How a PAMM account allocates gains and losses

Separate the decision from the allocation

A percentage allocation management model delegates trading decisions to a manager. The service records each participant’s share and distributes trading results according to its allocation rules. Identify which balance or equity figure counts and when the provider calculates the applicable weight for a trade or period.

Run the example both ways

Suppose the amount eligible for allocation is $20,000 and one participant contributes $2,000. That participant has a 10% weight. A $600 gain on the managed account gives the participant $60 before charges. Starting again from the same balance and weights, a $600 loss charges the participant $60. These are two alternative outcomes for the same starting position.

Account for changes in the pool

If another participant adds $5,000 before weights are recalculated and everything else stays fixed, the original participant’s share becomes 8%. The point at which cash enters or leaves the allocation depends on the agreement. Check the treatment of deposits, withdrawals, management fees and performance fees before comparing the gross example with an actual statement.

Reconcile the statement

Start with opening equity, identify cash flows, then isolate the allocated trading result and any charges. Compare the total with closing equity. This gives you a way to distinguish a trading loss from a withdrawal, or a smaller gain caused by a change in your allocation weight.
