Pertinent information is required to navigate numerous investment options successfully in the stock market. The chart should be used in making rational decisions when investing in stocks close to the sector average, not going too far from it unless there are compelling reasons to do so. This approach helps to remove emotions from investment decisions and place them on fundamentals while at the same time not being too far from the majority of investors. Investors who buy when the price of a stock is close to the average will find that they are not inclined to overpay for a stock. The net asset value of each company is incorporated into the chart. Investors can use this measure in assessing stock values. 
The chart also shows daily changes in stock prices and the percentage year to date price movement based on the last traded prices. Dividends that are paid or are due to be paid and yields for each company are shown in the Main and Junior Markets’ daily report charts, along with the closing volume of the highest bid and the lowest offer for each company.
