Solid tech earnings propelled the Nasdaq higher, helping the index close out Friday's session at a new record. Since Monday, Oct. 23, the tech-heavy index has increased 1.09%, its best gain in three weeks. 

The S&P 500 rose 0.23% since Monday morning, also reaching a new record on Friday. The Dow Jones Industrial Average ended 0.45% higher. 

This week marked the S&P 500 and Dow's seventh in the green.

Tech, Tech and More Tech

This week was the biggest of the earnings season with more than one-third of the S&P 500 opening up their books on the quarter. Technology earnings were among the most closely watched in the past few days and, for the most part, the largest industry players beat estimates. 

A softening U.S. dollar should take some of the credit for better-than-expected earnings in tech, Polaris Greystone's Jeffrey Powell told TheStreet.

"Sixty percent of the tech sector is international sales," Powell said in a call. "When you're pulling earnings from abroad, at least abroad for us, then having a strong dollar makes your products more expensive and makes them less competitive. It makes it harder to sell them."

Alphabet Inc. (GOOGL) - Get Report smashed Wall Street's third-quarter earnings expectations. The Google parent reported third-quarter net income of $6.73 billion, or $9.57 a share, coasting past analyst estimates of $8.31. Revenue surged 23% year over year to $27.7 billion, higher than the $27.2 billion analysts were expecting.

Traffic acquisition costs, or what Google pays to get ads in front of mobile users, spiked 54% during the quarter but Wall Street didn't seem too concerned since Google's overall ad business continues to grow.

The U.S. economy rose at a growth rate of 3% over the third quarter, according to a preliminary reading of GDP out on Friday. That pace slowed slightly from a 3.1% rate in the second quarter. The figure, however, came in faster than an expected 2.5% growth rate from July to September. Consensus showed a broad range heading into the report with economists divided on how large an impact a series of hurricanes on the south and southeastern continental U.S. and Puerto Rico might have had. Consumer spending increased 2.4%.

"Many on the street are no doubt applauding today's GDP report as a blowout win," Mike Loewengart, VP of investment strategy at E*TRADE, wrote in a note. "Given these numbers are coming on the heels of catastrophic hurricanes, it appears-by early measures-that the economy fared more than okay against a hostile economic adversary."

In other economic news this week, consumer sentiment in October settled at its best level in 13 years. The final reading of the University of Michigan's index came in at 100.7, slightly below an initial estimate of 101.1. September showed a reading of 95.7.

Excluding transportation, orders climbed by 0.7%. Core capital goods orders rose 1.3%. Orders increased 1.7% in August.

New home sales in the U.S. rose to a seasonally adjusted pace of 667,000 in September, a ten-year high, according to the Commerce Department. That was far higher than consensus of 555,000. August's number was revised to 561,000 from 560,000.

Calm Waters for Markets

Markets have managed to hit new heights recently with little volatility. The Volatility Index, otherwise known as the fear index, remained around 10 on Friday, Oct. 27 after hitting its lowest level ever on July 21 this year. 

"I feel like a broken record, but so many times when I'm talking about 2017, I usually say 'the last time since 1964, 1965, or 1995' when making comparisons to 2017," said Ryan Detrick, senior market strategist at LPL Research. "Those three years are widely considered the least volatile years ever, and 2017 is right there with them trying to make the medal stand."

LPL Research noted that the S&P 500 has not seen a daily drop of more than 0.5% in 33 straight sessions, its longest streak since 1995. So far this year, the index has fallen by 1% or more only four times, its fewest since 1964. Low volatility is in part tied to strong earnings, though LPL Research does expect an eventual return to normal volatility with the possibility of a correction as the "economic cycle continues to age."
