As appears from information models of a market microstructure the data accessible for traders during the auctions influence strategy of traders. Differently, market balance depends on degree of market transparency, i.e. capabilities of traders to observe process and results of trade. Because of transparency influences on the auctions many regulation authorities supervise procedure of disclosing of the information on transactions.
The most typical sign of the transparent market is availability to ordinary participants of the auctions of the information from the book of registration of warrants or about turn of requests. At many stock exchanges the information contained in books of specialists, doesn’t reveal, however specialists can allow glancing at the records. Electronic trading systems, on the contrary, always open the information on turn of requests. Availability of this data is only one of aspects of the transparent market. Degree of transparency can vary also depending on detailed elaboration of the data about operations of traders and timeliness of renovation of the information.
In some markets, for example, dealer, the preliminary information is accessible. Traders can observe only quotations (pre-trade information) and the data about transactions (post-trade information) is inaccessible to them. In other markets traders receive together with the preliminary information as well the post trading data, i.e. data on the prices of transactions and volumes of the auctions. On other end of a spectrum there are indicative off-exchange systems which don’t provide with the authentic data neither about quotations nor about operations.
The exchange market possesses high level of transparency at preserving of anonymity of the auctions. The trader during the auctions and on their results is provided with some information, beginning from turn of execution of requests and finishing the concluded transactions.
How much transparency of the auctions is favorable? If to follow traditions of the classical economic school assuming that economic agents act extremely rationally, processing the accessible information of transparency raises overall performance of a market mechanism. However the founder of the concept of an efficient market, the professor of the Chicago University G.Roberts has specified that the financial market is effective in weak degree.
Empirical researches of the exchange market have revealed that the hypothesis of rational expectations, at least, its initial not displaced version, as a whole is rejected in the middle and the long-term period. In certain approach short-term expectations can be characterized as rational, but with signs of “effect of general hobby». The econometric analysis of the domestic exchange market has revealed that on an one-day interval of time traders are inclined to “gregarious” behavior and week and monthly horizons of time are characterized, more likely, as adaptive, rather than rational expectations. In my opinion, possibility of supervision of process and results of trade underlies “gregarious” behavior (herding behavior).
