What is MFS (Margin Financing System) on the PSX?
MFS (Margin Financing System) is broker-provided leverage on the PSX: a brokerage finances part of its client's share purchases against the shares as collateral. Net open MFS positions per symbol, and their share of free float, are disclosed daily.
How it works
Unlike MTS, where financing is centralized through NCCPL, MFS credit comes from the broker's own book, making it the more common leverage channel. The daily report shows open financed value per symbol and the percentage of free float financed.
A rising share of free float financed through MFS means an increasing slice of the tradable stock is held on borrowed money — supportive while prices rise, but a source of forced selling in declines.

Common questions
How much of a PSX stock's float can be margin financed?
Exposure varies by symbol and broker risk limits; the disclosed metric to watch is the percentage of free float financed. Low single digits is routine — sustained readings above roughly 3–5% mark unusually crowded leverage.
