Here's what we're watching ahead of Friday's opening bell.

-- U.S. stock futures edged lower as some investors grew concerned that President-elect Joe Biden's $1.9 trillion Covid-19 relief plan could lead to higher taxes.

Futures tied to the S&P 500 fell 0.4%, putting the benchmark on course to decline for a second day. Contracts tied to the Nasdaq-100 were flat and those linked to the Dow Jones Industrial Average slipped 0.6%. Read our full market wrap here.

Retail sales declined 0.7% in December, as holiday shoppers avoided stores during a rise in Covid-19 cases.

What's Coming Up

-- A preliminary reading of consumer sentiment, due at 10 a.m., is expected to register a small drop.

Market Movers to Watch

-- Corporate earnings season kicked into high gear with updates before the bell from JPMorgan Chase, Citigroup and Wells Fargo. Shares of JPMorgan slipped 2% after its profit jumped 42% during the recent quarter. Wells Fargo dropped 4.1% after revenue fell more than forecast but profit broke a streak of misses. Citigroup shed 1.5% after its profit beat forecasts.

-- Shares of Blackberry jumped more than 20% premarket. The rise comes after the maker of the eponymous device from technology days of yore, now a security software and services company, saw its stock climb more than 20% on Thursday. Earlier this week Canada's the Globe and Mail reported the company had sold 90 patents to Huawei. No word on whether " Blackberry thumb" is going to become a thing again.

-- After surging for two days, GameStop shares are taking a break, falling 4.5% premarket. Some investors had pointed to a short squeeze as behind the recent jump.

-- Online resale marketplace Poshmark's shares fell 3.5% premarket, but held on to most of the prior day's gains, when its stock soared more than 140% in its trading debut.

-- Shares of Palantir Technologies are up more than 5% premarket, as investors appear unmoved by yesterday's downgrade of the stock from Citibank.

-- Energy giant Exxon Mobil's shares lost 3.5% before the open. The SEC launched an investigation after an employee filed a whistleblower complaint last fall alleging it overvalued one of its most important oil and gas properties.

-- Business-application software firm Progress Software reported higher-than-expected adjusted earnings and revenue for its most recent quarter. Its shares slipped 1.5% premarket.
