A new kind of stock market for large trades. Magma Trading will be the first wholesale market for broker-dealers to trade blocks of equities with each other.
The current market for US equities has no displayed trading venue for large blocks. Because of disincentives at other venues, large trades must often be split up into retail-size orders. As a result, the average trade size on the New York Stock Exchange is under 200 shares. The Magma team, which includes former executives from Lava Trading, has come up with a solution that allows buyers and sellers of blocks of stock to meet electronically.
