Optiver has strengthened its US institutional ETF trading offering with two new additions, as demand grows across the market.
Brett Sussman, Caitlin Krantz
Specifically, the firm has appointed Brett Sussman and Caitlin Krantz to its US-based team, joining as head of US institutional ETF sales trading and as a US ETF sales trader, respectively.
Both Sussman and Krantz’s additions are set to support counterparties looking to connect to Optiver’s global liquidity, market knowledge and execution capabilities across the ETF landscape.
New York-based Sussman joins the firm after almost nine years at Flow Traders, where he initially began as an institutional trader, before stepping up as head of institutional sales and trading, Americas, seven years later.
Prior to this, he held various roles at Citi, working across equity derivatives, leverage credit and rates trading.
