Thousands of stocks are listed on the Nasdaq, including those of iPhone maker Apple (AAPL.O), opens new tab, electric vehicle-maker Tesla (TSLA.O), opens new tab and artificial intelligence semiconductor powerhouse Nvidia (NVDA.O), opens new tab.
Technical glitches on exchanges can roil markets, hit traders’ confidence and attract scrutiny from the Securities and Exchange Commission.
A glitch at the New York Stock Exchange last year prevented the opening auctions for a slew of stocks, prompting widespread trading halts, confusion over whether orders were being filled at correct prices and trades in more than 250 securities being busted.
However, outages at major exchanges have been largely contained in recent years.
“The Nasdaq stock market has resolved its earlier matching engine issues and all systems are operating normally,” the company said on its website. It did not immediately respond to a request for further comment.
The exchange operator had reported similar issues in December, when stock orders were impacted and over 50 clients at the exchange were affected.
The glitch on Monday impacted orders sent using the “RASH FIX” order handling system. FIX, or Financial Information Exchange, is a message protocol that defines an electronic message exchange for communicating securities transactions between two parties.
The issue also led to self-help declarations against Nasdaq from Cboe (CBOE.Z), opens new tab and New York Stock Exchange Arca Equities, which specializes in listings of exchange-traded products.
A “self-help” is a notification issued by a trading exchange when another exchange is dealing with internal problems processing trades and orders are routed through alternate venues.
