When bonds are issued I agree they should be listed as individual issue listings as they could have different maturities and interest rates.
Shares in a company are a different issue and I would ask you to consider the following changes.
A: Market Capitalisation leader board should have every company starting at 2 million. When shares are issued at 2g that would not change - just the ownership of the shares would change. When the unit price on the market changes, so does the market capitalisation.
B: If different tranches of shares are issued they should be grouped together under the one listing showing how many issued to public and how many in total.
C: Dividends when paid should be paid uniformly for all shares issued to the public
D: Perhaps more difficult, but permissible pricing of shares should reflect a multiple of net profit after tax for the previous year / years rather than just net assets.
