Use SPARKLINE column chart to create price chart with reference price

I own and follow several stocks in my investment portfolio. I pick a reference price for each stock. To effectively track the movement of a stock, I need to visualize its 52-week prices based on the reference price that I determined. In this post, I explain how to do so with the SPARKLINE column chart in Google Sheets.

Use SPARKLINE column chart to show stock price trend in Google Sheets

Concept

Everyone who uses the GOOGLEFINANCE function and SPARKLINE function in Google Sheets can easily find examples in this documentation about drawing a chart inside a cell to display stock price trends during the last 30 days, last 52 weeks, etc. For example, to display the last 52-week price trend for the NVIDIA Corporation stock:

SPARKLINE(INDEX(GOOGLEFINANCE("NVDA","price",EDATE(TODAY(),-12),TODAY())))

Use SPARKLINE function to display the last 52-week price trend for the NVIDIA Corporation stock in Google Sheets

However, those are only the simplest uses of the SPARKLINE function and can only offer little information for watching stocks. As I have a reference price for each stock in my watching list, I need to benchmark the price movement with that reference price. Concretely:

  • If stock prices are lower than the reference price, I want to draw those in red color.
  • If stock prices are greater than the reference price, I want to draw those in green color.

After spending lots of time learning available options for the SPARKLINE function, I find the solution as follows:

  1. As usual, I use the GOOGLEFINANCE function to get historical prices of a stock, for example, during the last 30 days, during the last 52 weeks, etc.
  2. I then subtract the reference price from those prices returned by the GOOGLEFINANCE function. As a result, I have negative and positive numbers but the general trend is conserved.
  3. I then put those offset prices into the SPARKLINE function and specify the options so that:
    • The negative numbers are plotted with red color.
    • The positive numbers are plotted with green color.

The idea of this solution is quite simple as explained above. However, there are still several technical details worth mentioning for the implementation.

Implementation

Get last 52-week prices of stocks in Google Sheets

For example, to get the last 52-week prices for the Microsoft Corporation stock, I would use the formula below:

GOOGLEFINANCE("MSFT","price",EDATE(TODAY(),-12),TODAY())

Where:

  • MSFT is the symbol for the Microsoft Corporation stock
  • EDATE(TODAY(),-12) is the date 12 months (as same as 52 weeks) before today.

As a result, I have a table of two columns Date and Close.

Extract only the prices and ignore the dates

In the post GOOGLEFINANCE Best Practices, I explained many useful practices for working with the GOOGLEFINANCE function in Google Sheets. Among those practices, I explained how to extract only the prices and ignore the dates from the result returned by the GOOGLEFINANCE function. This is necessary because I only need the prices as input to the SPARKLINE function. Here is an example:

=SLICE(INDEX(GOOGLEFINANCE("NASDAQ:TSLA","price",TODAY()-7,TODAY()),0,2),1)

Keep only the price with GOOGLEFINANCE

Choose the reference price

The reference price for each stock can be chosen based on personal preference. For example:

  • For stocks that I own in my investment portfolio, I use their FIFO unit cost basis as the reference prices. I have explained in details in the post Compute cost basis of stocks with FIFO method in Google Sheets.
  • For stocks that I do not own in my investment portfolio, I could pick a price that I consider reasonable for myself.

Once again, the choice depends totally on personal preference.

Subtract the reference price from an array of prices

To subtract the reference price from an array of prices, I use the ARRAYFORMULA function in Google Sheets. For example, to subtract 100 from the prices of the TESLA stock last 7 days, I would use:

Use the ARRAYFORMULA function to subtract the reference price from an array of prices

Use SPARKLINE column chart

With the prices offset by the reference price, I can put them into the SPARKLINE function and specify the options so that:

  • The chart is a column chart.
  • The negative numbers are plotted with red color.
  • The positive numbers are plotted with green color.

For example, below is the result of plotting the last 52-week prices of the Amazon.com, Inc. stock with the reference price is 125.

=SPARKLINE(ARRAYFORMULA(SLICE(INDEX(GOOGLEFINANCE("AMZN","price",EDATE(TODAY(),-12),TODAY()),0,2),1)-125),{"charttype","column";"negcolor","red";"color","green"})

Use SPARKLINE column chart to show stock price trend of AMAZON stock in Google Sheets

How to convert column index into letters with Google Sheets

How to convert column index into letters with Google Sheets

In Google Sheets, rows are indexed numerically, starting from 1, but columns are indexed alphabetically, starting from A. Hence, it is pretty straightforward to work with rows and trickier to work with columns as we need to convert between column index and corresponding letters. For example, what are the letters of column 999th in Google Sheets? In this post, we will look at how to convert a column index into its corresponding letters by using the built-in functions of Google Sheets. What are letters of the column 999th in a spreadsheet? Unfortunately, Google Sheets does not provide a ready-to-use function that takes a column index as an input and returns corresponding letters as output. However, there is a little trick of combining other available built-in functions to do the task. In Google Sheets, there is the ADDRESS function that returns the cell reference, according to the specified row index (first parameter) and column index (second parameter) in the input. For example,

Create a dividend income tracker with Google Sheets by simply using pivot tables

As my investment strategy is to buy stocks that pay regular and stable dividends during a long-term period, I need to monitor my dividends income by stocks, by months, and by years, so that I can answer quickly and exactly the following questions: How much dividend did I receive on a given month and a given year? How much dividend did I receive for a given stock in a given year? Have a given stock's annual dividend per share kept increasing gradually over years? Have a given stock's annual dividend yield been stable over years? In this post, I explain how to create a dividend tracker for a stock investment portfolio with Google Sheets by simply using pivot tables.

Slice array in Google Sheets

Slice array in Google Sheets

Many functions in Google Sheets return an array as the result. However, I find that there is a lack of built-in support functions in Google Sheets when working with an array. For example, the GOOGLEFINANCE function can return the historical prices of a stock as a table of two columns and the first-row being headers Date and Close. How can I ignore the headers or remove the headers from the results?

Compute cost basis of stocks with FIFO method in Google Sheets

After selling a portion of my holdings in a stock, the cost basis for the remain shares of that stock in my portfolio is not simply the sum of all transactions. When selling, I need to decide which shares I want to sell. One of the most common accounting methods is FIFO (first in, first out), meaning that the shares I bought earliest will be the shares I sell first. As you might already know, I use Google Sheets extensively to manage my stock portfolio investment, but, at the moment of writing this post, I find that Google Sheets does not provide a built-in formula for FIFO. Luckily, with lots of effort, I succeeded in building my own FIFO solution in Google Sheets, and I want to share it on this blog. In this post, I explain how to implement FIFO method in Google Sheets to compute cost basis in stocks investing.
