@awfireman @Snkeyez121 Quote - Benefits and Risks of Market-on-Close Orders There are a number of situations in which an investor might want to get the closing price of a security. If you suspect that a company's stock might move drastically overnight—as the result of a scheduled after-hours earnings call or an anticipated news story, for example—then placing a MOC order would ensure that your purchase or sale would take place before the news breaks the next day. I think someone expects big news in AM or big swing in price.
