Our take
Innovations in fintech infrastructure have dramatically changed how people invest, but despite such developments, investors still face limitations when trading assets. Exchanges often list out-of-date pricing information, which limits investors' abilities to make strategic investment decisions, a problem that is heightened through knock-on effects from other unstable stock prices.
IEX provides a registered US stock exchange for investors and broker-dealers, focusing on providing a more stable trade execution experience than existing exchanges. The company achieves this through its "Speed Bump" strategy that delays trades to gather up-to-date pricing information whilst assessing them for price stability, ensuring that trades are not executed based on stale data, and helping to notify other orders to react to other stock price stability levels.
Whilst the company must share the stock exchange sector with many competitors, IEX shows great promise through its focus on maintaining pricing accuracy and stability. The company also stands out by providing a cloud platform for the selling, sharing, and use of financial data, in addition to an investment lifecycle advice tool for institutional investors.
