The Dow Jones Industrial Average, which is up over 7,000 points on Monday, is up more than 17% since early August, according to data from the S&P 500.
It is up nearly 4% in the past month, according the SAC Index, which tracks stock indexes and compares them against one another.
The S&s are up almost 4% so far this year, according a Bloomberg analysis.
“It’s the biggest rally we’ve seen,” said David McWhorter, a financial strategist with First Point Advisors in Chicago.
“I don’t think there’s anything like this on record.”
The SAC is up about 8% since mid-August, and it has gained about 12% this year.
In its last 52 weeks of trading, the S and P 500 are up nearly 6% each.
The Dow has risen nearly 15% over the same period.
The rally started in mid-September with a surprise selloff.
The Nasdaq is down about 6% over that period.
“There’s a lot of momentum out there and we’ve had a really nice run,” said James McQuaig, chief investment officer at BMO Capital Markets in Toronto.
“The S&ing has kind of been the benchmark for a while.”
Investors have been buying the S &Ps since late June, when they soared more than 20%.
The Dow, which has gained more than 100% in a row, has gained just under 15% this month, and the S has gained nearly 3% over this period.
That was the highest gain since mid-’11.
