1. Relationship between market supply and demand: When the goods in the market are in short supply, the price will skyrocket on the delivery day. Changes in the relationship between supply and demand will lead to fluctuations in market prices, especially when the delivery date is approaching, and insufficient supply will lead to price increases.
2. Speculation: A few days before the delivery date, speculative capital will concentrate on fleeing, leading to skyrocketing prices. Because financial futures have the characteristics of leveraged trading, investors need to close their positions before maturity, which leads to a large number of trading orders.
3. Market expectation: The market expectation of the delivery date price will also affect the price fluctuation. The market expects the price to rise, which leads to the sharp rise in the delivery date.
