To look at a company's performance over a certain time period please follow the steps below:

Step One: Go to the “Investing” page - from here you can click on the charting link.

Step Two: Put the company’s ticker into the “Main Settings”. If you do not know the company’s ticker then click on the “Look up ticker”. In the pop up window put the company’s name and then click on search.

Once the window shows you the list of options – click on the company you want and then once again – click on select!

This will then put the ticker into the Main Settings.

Step Three: Decide what time period you would like and then choose it from the drop down menu.

Step Four: You can also change the style of chart using the drop down.


Line Chart - Display closing prices only in the form of a line so that you can easily detect the rising and falling of a security.

Area Chart - Area charts shade in the area below the line in colour to more easily display the market peaks and troughs.

Candlestick Chart - Candle charts show the same information as a OHLC chart, however the difference between the open and the close is displayed as a solid body. A blue body indicates that the close on a certain day was above the open, and a red block indicates the market has closed below its opening price. These charts are not available on periods over 6 months.

HL Chart - HL charts show two price points per day on a vertical line. As the abbreviation suggests these two points are the High and Low price and show the trading extremes for each day. These charts are not available on periods over 6 months.

OHLC Chart - Open/High/Low/Close charts, or Bar charts as they are better known, show four price points for each day on a vertical line. The top and bottom of the line represent the high and low respectively. Notches on the left and right of the line represent the open and close respectively. These charts are not available on periods over 6 months.

Logarithmic Chart - Charts are normally displayed on an arithmetic price scale with equal weighting given to all price scale points. On an arithmetic price scale equal weighting is given to a move between 100 and 200 as a move between 900 and 1000. This represents a move of 100 points and would be reflected as such. On a logarithmic scale this would be represented differently. Logarithmically the move between 100 and 200 is represented as a 100% increase in price whereas a move between 900 and 1000 would not. To summarise on a logarithmic scale a move between 500 and 1000 would be represented on the price scale in the same way as move between 1000 and 2000. This has the effect of smoothing out a securities rise or fall. Well-known examples of logarithmic scales include the Richter magnitude scale for measuring earthquakes. Logarithmic scale charts are best used over long periods of time where the value of the underlying security has a very large price range.
