 U.S. stock markets look to end this trading week on a positive bias following yesterday's muted session, which saw the Dow 30 stocks and the S&P 500 inch higher by about 0.1%, while the tech-laid Nasdaq index was the relative outperformer of the three major averages, advancing 0.3%. Today, investors will consider the PCE deflator, which is considered the preferred inflation gauge by the Federal Reserve.
