There is two parts to this problem. Certain data needs to be made public and has to be truthful. On the other hand anybody should be able to make their own opinion of what is the value of the company based on the data. Everybody who sells will want to increase the "official" valuation and everybody who buys will want to do as cheap as possible. Everybody is free to try to sell at any price they want and everybody should be free to decide not to buy it. There are certain exceptions... but stock exchange I think should not be one of them.
