After its stock traded below $1 for 30 consecutive days Molycorp (MCP) received a delisting notice from the NYSE on December 30, 2014. An average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of that month.
The listed closing price is the last price anyone paid for a share of that stock during the business hours of the exchange where the stock trades. The major U.S. exchanges are generally open from 9:30 a.m. to 4 p.m. Eastern time. The closing price is just a snapshot of the stock at 4 p.m. This price does carry a lot of psychological weight, as it's often interpreted as the market's final say on a stock for the day.
