The historic fall came shortly after the previous single-day record drop was recorded on Thursday with 3.23 percent slide since it was established on Nov. 25, 2011, according to the Danish news agency Ritzau.
All 20 Danish blue chip companies ended Monday in the red, with Danske Bank and A.P. Moller-Maersk stocks taking the lead, followed by other major Danish companies including Carlsberg, Pandora and Vestas.
"The market has been nervous the past few days and many are fearing a recession in China," Mads Zink, Danske Bank's head trader, was cited by Ritzau as saying.
The C20 also registered a drop of a 2.6 percent on Friday.
