Create a new Power BI report.
Note that if you want to make this exercise more exciting, you could get the data directly from the source - in this case https://tinyurl.com/y28ohs7r.
Load the data from the workbook in the above folder - you should see something like this:
The initial list of shares, which is begging to be tidied up!
In Query Editor, carry out the following transforms:
- Choose to Use First Row as Headers (this may not always be necessary).
- Remove all but the first, second and fifth columns.
- Rename the remaining columns as shown below.
You should now be looking at something like this:
The remaining table of data.
Your prices are left-aligned, which suggests that Power BI is treating them as text. Change the data types of the last two columns so that they are (decimal) numbers:
Better - now we can do arithmetic on these columns ...
Choose to add a new column:
Choose to add a column using this icon.
Create a column which subtracts the last closing price from the current one, rename it and sort by it to get:
It's been a good day today for holders of shares in NMC Health PLC.
Save this data back into Power BI proper, and use it to create a simple table:
Totals would be meaningless in this context, so you should choose not to display them.
Save this report as Equity, then close it down.
