I’m posting this here because the inspiration came from Saul’s description of his charts and a spreadsheet recently shared by Phoolio18. I have been working on a Windows application that can display a Price/PE chart loosely based on my understanding of how Saul charts price vs. earnings. I know my display is different but I hope it encapsulates the same idea. It is still a work in progress but the basic functionality is there. The link below is to a screen capture saved on Google Drive.
The price chart is a two-year history and current price from Yahoo! Finance. The silver rectangles represent a PE range of 15-20 for each quarter for the earnings data available. That range can be easily adjusted up or down or expanded and contracted using the controls to the left of the chart. The earnings numbers are listed in the grid view on the lower left. Date and EPS values can be changed by simply typing over the values. All of the earnings information is stored in a simple text file. Options for linear or logarithmic scales for the Price axis are shown, but only linear is available so far. The current price, PE and the 1YPEG number that has been recently discussed on this board are displayed on the upper left, below the company selection box. (I need to add a Refresh button there.)
The small window to the left pops up when either Add button is clicked. This would be to add new earnings to an existing company or to add a new company. A single amount can be entered in the top section or a list of multiple date/amount values can be entered (or pasted) into the lower section. That’s intended to be handy in case someone were to share earnings values on a discussion board or something.
I still have work to do on it, like the ability to delete a company that was no longer interesting, although that shouldn’t be needed often.
I’d be interested in any comments or observations of flaws in the idea. Thanks Saul and Phoolio18 for the inspiration and the numbers.
