Friday's a short trading day; Target upbeat on Black Friday

U.S. stock futures were tilting higher Friday, as investors shrug off a plunge in Chinese equities as they get ready for a shortened post-holiday session.

Updates from retailers with Black Friday sales will be watched closely.

Futures for the S&P 500 picked up 2.2 points, or 0.1%, to 2,090.25 and those for the Nasdaq-100 rose 14.75 points, or 0.3%, to 4,692. Futures of the Dow Jones Industrial Average were off 8 points at 17,854.00, but had darted into positive territory.

Markets seemed largely unrattled by a rout on the Shanghai Composite Index Friday, which came after Chinese stock regulators launched investigations (http://www.wsj.com/articles/citic-securities-probed-by-chinas-stock-market-regulator-1448537277) into two major Chinese brokerages over suspected violations of securities rules.

Before the Thanksgiving break, U.S. stocks closed mixed in Wednesday's thinly-traded session (http://www.marketwatch.com/story/us-stock-futures-rise-as-wall-street-focuses-on-data-not-global-tensions-2015-11-25). The S&P 500 fell less than 1 point to 2,088.87. The Dow industrials edged up 1.2 points to 17,813.39, and the Nasdaq rose 0.3% to 5,116.14.

For the abbreviated week, the Dow was on track to rise 0.9%, and the S&P 500 was in line for a 0.5% advance. The Nasdaq looks like it may fare better, with a 1.2% rise.

Light session: Trading volumes should be light, as markets are only open for a half day (http://www.marketwatch.com/story/when-do-markets-close-around-thanksgiving-2015-11-23) after the closure for Thanksgiving Day holiday on Thursday.

The New York Stock Exchange and the Nasdaq will close at 1 p.m. Eastern Time, while the Securities Industry and Financial Markets Association is recommending a 2 p.m. Eastern closure for the bond market.

No economic data are slated for release.

Black Friday: Millions of Americans are expected to hit the stores or shop online for discounted electronics, clothing and other items.

Retailers "have swamped newspapers and social media with advertising. Traders will be waiting to see who is first to report 'record sales' from today's shopping bonanza," said Alastair McCaig, market analyst at IG, in a note. "As ever, the devil will be in the detail, and seasoned traders are only too aware that record sales do not automatically translate into record profits."
