Following Friday’s disappointing jobs report, market participants are now virtually certain that the Federal Reserve will announce that it will resume buying assets at the conclusion of its November meeting and do so in a sizeable way, according to an exclusive CNBC Fed Survey.

Nearly 93 percent of the 70 respondents, including economists, fund managers and traders, believe the Fed will boost the size of its portfolio, up from 69 percent in the survey two weeks ago.

Of those who expect the Fed to move, 86 percent look for an announcement in November, up from 38 percent in the last survey.

Market participants forecast that the Fed will announce plans to purchase $500 billion in assets at the conclusion of the upcoming meeting, the first time the question has been asked.

Despite the $500 billion average, expectations for the November announcement span a range from $100 billion to as high as $1.5 trillion.
