Yes, if you specify a 'normal' web browser as user agent you do get the
request = urllib2.Request('http://www.marketwatch.com/story/mondays-biggest-gaining-and-declining-stocks-2009-07-27')
request.add_header('User-Agent', 'Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:18.104.22.168) Gecko/2009073021 Firefox/3.0.13')
opener = urllib2.build_opener()
page = opener.open(request).read()
