This is my version of the Stock Market table. For a start it is a lot bigger, the same size as the map board. This is because it not only holds the Stock Market Table but also the Bank Pool, the Train Pool and the shares of the Initial Offering (as well as a couple of small tables, one of which can be seen in the picture).
On the Stock Market Table, each Company has their own separate horizontal line to keep track of share price. Since it is also possible for the share price to go up 1, 2, 3 or 4 steps each OR, I have included a look up table at the base to help work out how many steps it is due to rise (or not).
