Jan 12 (Reuters) - Wall Street's main indexes opened higher on Wednesday after consumer prices data that largely met expectations eased some concerns about faster-than-expected interest rate hikes, with big technology stocks leading the advance.

The Dow Jones Industrial Average rose 84.14 points, or 0.23%, at the open to 36,336.16.

The S&P 500 opened higher by 15.52 points, or 0.33%, at 4,728.59, while the Nasdaq Composite gained 109.65 points, or 0.72%, to 15,263.10 at the opening bell. (Reporting by Shreyashi Sanyal in Bengaluru; Editing by Maju Samuel)
