Price discovery mechanism

The price discovery process (also called price discovery mechanism) is the process of determining the price of an asset in the marketplace through the interactions of buyers and sellers. The futures and options market serve all important functions of price discovery. The individuals with better information and judgement participate in these markets to take advantage of such information. When some new information arrives, perhaps some good news about the economy, for instance, the actions of speculators quickly feed their information into the derivatives market causing changes in price of derivatives. These markets are usually the first ones to react as the transaction cost is much lower in these markets than in the spot market. Therefore these markets indicate what is likely to happen and thus assist in better price discovery.

The intention of this change was to stop companies overvaluing the assets they held. Each night (or reporting period) they would have to take a recently discovered market price obtained from two or more market observers.

Recent changes in market regulations, post Lehman Bros, have outlined practices that affect the price discovery mechanism. Price discovery is sensitive to many factors. Consider for a specific execution venue the following inputs drive the price discovery mechanism.
