Market maker 做市商定義

何為做市商?

做市商指為促進流通性及確保金融市場暢順運作而買賣大量特定資產的市場參與者。做市商可以是個人,但由於受達至必需交易容量所需之每項資產的數量限制,更常見的做市商參與者為大型機構。

做市商會有其交易的若干數量的資產。透過顯示買入和賣出報價並以此價格迅速執行交易,做市商能創造出一種直接的交易方式。

做市商在股票交易中最常見,但亦可以參與其他市場。以股票市場為例,做市商只可以賣出他們自己購入數量的股份。然而,他們有責任滿足正常市場規模 (NMS),亦即證券的最低數量;該數量視乎個別股份而異。IG 利用做市商來為部分流通性不足的股份定價。

做市商的定義源自按照供求需要將市場價格設於不同水平以尋求平衡的行為。當市場出現波動的時候,做市商必須維持穩定並繼續為市場表現負責,這令他們必須承受巨大的風險。亦因如此,做市商會透過在其供您交易的資產中收取點差來獲利,以彌補購買可能貶值之資產的風險。

做市商的示例

做市商可能提出向您購買 100 股,每股售價 100 英鎊(賣出價格),並提出向另一名買家以每股 100.05 英鎊的價格賣出(買入價格)。儘管差額只有 0.05 英鎊,但在大量交易中,收益很快就會累積起來。
