Market makers are licensed broker-dealers that work for firms to mitigate client orders in the open market. They compete with other market makers by posting the requiredbid and askprice and size quotes for every stock they make a market in. Market makers get order flow information and will trade in the open market to fill the order for a profit. The profit comes from thespreadbetween what they paid for shares compared to what the client is charged. When market makers complete large order transactions, they will often post the blocks on time and sales. Unusually large blocks are likely market maker transactions that have been completed earlier.
Market makers work for broker-dealer firms. As the name states market makers make markets in stocks. They are licensed dealers that are obligated to provideliquidityand assume the risks associated with holding an inventory of shares in stocks they cover in order to maintain an orderly market and facilitate trade transactions. They are obligated to always provide a bid and ask quote during market hours and be ready to buy and sell at least 100 shares of stock they make a market in. They compete with other market makers and electronic communication networks (ECNs) for trades and try to profit from the bid and ask spread of their fills. When an institution decides to buy or sell a large amount of stock, they will spread their block orders through multiple market makers to attain an efficient average price without making too much market impact. As the role and access of ECNs and dark pools has grown through the years, market makers have seen a steady decline in numbers and activity. Market makers are some of the largest users ofhigh frequency trading(HFT) and algorithmic trading programs, which account for up to 70% of all daily trading volumes.
