U.S. stock index futures indicated a higher open Wednesday with investors reacting to a rebound in the price of oil and some strong data from China.
Helping to bolster market sentiment, China's services sector strengthened in March, according to a survey of smaller and medium-sized enterprises released earlier in the day. The Caixin services purchasing managers' index (PMI) for March rose to 52.2, up from February's reading of 51.2.
U.S. oil prices built on Tuesday's slight gains, rising over 2.5 percent Wednesday.
Nonetheless, Asia markets wavered between positive and negative territory overnight. European markets fared better, posting some gains in the morning session after closing sharply lower on Tuesday evening.
