Recently in Argentina there were news of a case were 400 people in a boat were exposed, quarantined and then tested. From official government sources, of all that tested positive, 70% were asymptomatic. Edit: I rechecked, the numbers are right but apparently this has been the first test. It hasn't passed enought time to see if those that tested positive, but were asymptomatic, later on develop symptoms.
