2017 has been a year of records on Wall Street, and the latest to fall under the unceasing bull market has stood for more than 20 years.

The Dow Jones Industrial Average DJIA, -1.92% closed at a record on Monday—rising 0.6% on optimism related to a tax bill passing in Washington—marking the average’s 70th record close of the year. That represents the highest-ever number of record closes in a year, topping the 69 records that occurred over 1995.

The S&P 500 SPX, -2.37% has closed at records in 62 sessions, as of Monday’s close. This represents the second-highest annual tally for the benchmark index; in 1995 it ended at records 77 times. That record will stand for now, as there are not enough trading days left in the year for the benchmark index to surpass that record, even if it were to close higher in each of them.

The Nasdaq Composite Index COMP, -3.01% has closed at a record 72 times thus far this year, thanks to the strong outperformance of large capitalization technology and internet companies, which have contributed a sizable percentage of the broader market’s advance. 2017’s tally is easily the highest ever recorded by the Nasdaq in a year. The previous record, in 1980, had 62 closing records.

This is the fifth straight year where the Dow has closed at a record at least once. The blue-chip average posted 26 record closes in 2016, six in 2015, and 38 in 2014. There were no records between 2008 and 2012, as the market recovered from the financial crisis, but it came back in a big way in 2013, when the Dow posted 52 records.

The sheer number of Dow records is a sign of how unceasing the market’s move higher has been this year. On a total-return basis, the S&P has risen for 13 straight months through November, an unprecedented streak.

Global stocks, meanwhile, haven’t had a down month since October 2016, and no matter what happens in December, 2017 will be the year with the fewest monthly declines in the history of the world index. Of course, if December ends in the green, that would represent the first year ever without a single monthly decline.

As Richard Turnill, BlackRock’s global chief investment strategist wrote in a note, “2017 was a near-perfect year for risk assets.” He noted that the MSCI All Country World Index closed at a record 61 times this year.

2017 was also a notable year for how lacking in volatility it was.

According to the WSJ Market Data Group, the average absolute daily percentage change for the Dow was 0.31% in 2017. It was 0.3% for the S&P, and in both instances, that represents the smallest absolute daily percentage change since 1964. For the Nasdaq Composite Index COMP, -3.01% , the absolute daily percentage change was 0.44%, the smallest since 1989.

Data from S&P Dow Jones Indices showed that the average observed one-month volatility in the S&P 500 was lower than any other year since 1970.

The S&P 500 has gone a historic length of time without a drop of 3% from a peak, something that is historically extremely common. Of the 56 lowest closing levels in the history of the Cboe Volatility Index VIX, +6.12% (since 1990), 47 of them occurred this year, per S&P Dow Jones data. The so-called “fear index” also notched two all-time closing lows.
