By Anora Mahmudova and Barbara Kollmeyer, MarketWatch

NEW YORK (MarketWatch) -- The Dow Jones Industrial Average dropped below 17,000 on Friday on disappointing earnings, leaving it with its biggest weekly decline in six weeks.

Big declines consumer discretionary stocks, led by Amazon.com, pushed the S&P 500 away from the record close set on Thursday.

But one of the day's standouts was fast-food chain El Pollo Loco(LOCO), whose shares surged 60% to $24 on their trading debut, after the initial public offering was priced at $15.

The Dow Jones Industrial Average (DJI) lost 123.23 points, or 0.7%, to 16,960.57, weighed down by losses in Visa Inc. For the week, the blue-chip index fell 0.8%, its biggest weekly loss since June 14.

A big contributor was Visa Inc. (V), which dropped 3.8% after the credit-card company trimmed its forecast for annual revenue growth.

The S&P 500 (SPX) closed 9.6 points, or 0.5%, lower at 1,978.34 and finished the week roughly where it started it. The Nasdaq Composite (RIXF) shed 22.5 points, or 0.5%, to 4,449.56, but eked out a weekly gain of 0.4%.

"Today's action is all earnings-related. At this point," said Kate Warne, investment strategist at Edward Jones.

"Investors pay attention to guidance from companies, and the lowering of the outlook from Visa signalled that perhaps the second half is not going to be as strong as previously thought," she added.

Investors also were disappointed with Amazon.com(AMZN) and a wider-than-expected second-quarter loss late Thursday. Shares plunged 10%. Also read: Is Amazon spending like a drunken sailor?

Pandora Media(P) dived 11%, after the Internet-based radio company posted wider losses late Thursday.

Cynk Technology (CYNK) plunged 85%, after trading in the stock resumed following the suspension by the SEC earlier this month.

Meanwhile, orders for durable goods such as computers, aircraft and heavy machinery rose a solid 0.7% in June, offering a sign of a general upswing in business spending. But investors showed little reaction.

Next week has the potential to be big for economic news, with a Federal Open Market Committee meeting and the monthly jobs report topping a long list of data on the docket.

European stocks drifted into the red on Friday, with German stocks under pressure after weaker-than-expected German Ifo business sentiment data. The blue-chip MICEX in Russia fell 1.4%. Russia's central bank hiked interest rates on Friday, citing geopolitical tensions and the potential impact on the ruble and rising inflation as reasons. The European Commission submitted proposals on new sanctions for Russia linked to the Ukraine crisis on Thursday.

In Asia, the Nikkei 225 index rallied more than 1% on Friday to the highest settlement in six months, as the yen weakened and domestic inflation data met market expectations. China's Shanghai Composite also put on a strong performance, up 1.1%.

Crude oil (CLU4) was flat, and gold (GCU4) surged in late trade to settle above 1,300 per troy ounce. The euro (EURUSD) fell against the dollar after the weak German Ifo data.
