After the record finish, US futures show a mixed start to the day's proceedings on Wall Street.
Likely to be of big interest is Rovio Entertainment, which makes the game Angry Birds, which priced its IPO (initial public offering) and has now started trading in Helsinki and will begin changing hands on NASDAQ Helsinki's official list on October 3.
It priced shares at €11.50 (US$13.50) a share, valuing the Finnish tech firm at over US$1bn, and on debut, shares added over 5%.
Some commentators suggested that given that the IPO was multiple times oversubscribed, the share rise at launch was not so overtly large.
Congratulations to @Rovio as they take flight today! https://t.co/GDE5c7vmvo
