US stocks weaker on mixed corporate earnings

Major US equity indices witness a weaker opening on Tuesday and were being weighed down by concerns over the US President Donald Trump's ability to push through his pro-growth economic policies.

Late Monday, Senate GOP leaders abandoned their effort to repeal and replace Obamacare after two more Republican senators announced their rejection to pass the US President Donald Trump administration's top legislative priority. 

Meanwhile, disappointing earnings report from Goldman Sachs added to last week's mixed quarterly results from JPMorgan, Wells Fargo and Citigroup, and failed to excite investors.

Among other individual moves, Netflix jumped over 9% on larger-than-expected growth in subscribers, while shares of Harley-Davidson slumped over 10% on lowered guidance for the year.

Against the backdrop of recent US data disappointment, investors would keep a close watch on corporate earnings in order to justify the current high valuations amid uncertainty over Trump's promised pro-growth reforms.

During the opening hour of trade, the Dow Jones Industrial Average lost nearly 50-points to 21,580, while the broader S&P 500 Index shed over 3-points to 2,455. Meanwhile, tech-heavy Nasdaq Composite Index trimmed around 5-points to 6,310.
