U.S. stock index futures pointed to a lower open Thursday, as investors braced for a pullback from record levels. Wall Street also tried to shake off negative sentiment coming from the European political space.
Dow Jones industrial average futures fell 97 points. Shares of Dow-component Nike fell 1.9 percent in the premarket after analysts at Goldman Sachs downgraded the stock to neutral from buy.

The pullback in the futures market took place exactly 30 years after "Black Monday," the worst day in the history of the U.S. stock market. On that day, the S&P 500 plunged 20.5 percent and the Dow dropped 22.6 percent.

The Dow rose sharply on Wednesday to close above 23,000 for the first time.
In Europe, the Spanish central government stated that it would move to suspend Catalonia's autonomy after regional leader Carles Puigdemont failed to drop a bid for independence or provide clarity on the matter.

Meaning, the government is set to meet Saturday to propose measures to strip Catalonia of some powers and officially trigger Article 155.
The news out of Spain weighed on European equities. The German Dax slipped 0.8 percent, while the FTSE 100 fell 0.6 percent. Spain's Ibex 35 pulled back 0.9 percent.
