Backwardation occurs when a bid price exceeds the ask price.
This usually occurs when stock is suspended or under a share repurchase scheme.
It can also mean that a futures contract will trade at a higher price when it is coming close to expiring.
The opposite of backwardation is known as contango.
After-hours trading involves buying or selling securities outside of specified trading hours.
However, trading after hours may offer less liquidity, as fewer traders are operating at these times and spread betting firms may offer wider spreads as fluctuations can occur during these times.
