SEC suspensions are for 10 trading days. When the suspension ends, the stock can be traded on the grey market but market makers are prohibited from publishing quotes (bids and asks). Shares can only be sold if there is a matching buy order (or combination of orders) at the same price and size.
Most suspended stocks trade very little if at all following a suspension. A few wildly popular cult stocks may continue to trade, but on much lower volume and prices. There are true believers who will buy the stock thinking it will all work out. Eventually even virtually all of those cease trading altogether as well.
