Compare stock portfolio to compound interest saving account

In investing, it is important to define the target that we want to achieve. Many investors like to compare their portfolios with a market index, but is outperforming the market index a good target? It is not a quantitative target to be measurable as market indexes fluctuate daily. I, personally, aim only for 10% growth a year. If at the end of the year, I see my portfolio grows 10%, I am pleased with that result no matter that S&P500 grows 50% the same year. To see if my stock portfolio grows in line with the 10% target, I choose to compare it to a saving account with the same interest. In this post, I will show you how to use a fictive saving account with daily compound interest as the target to benchmark a stock portfolio. Idea Computation Visualization Evolution of target saving account with 5% annual compound interest Evolution of target saving account with 10% annual compound interest Evolution of target saving account with 15% annual compound interest Conclusion

Create personal stock portfolio tracker with Google Sheets and Google Data Studio

I have been investing in the stock market for a while. I was looking for a software tool that could help me better manage my portfolio, but, could not find one that satisfied my needs. One day, I discovered that the Google Sheets application has a built-in function called GOOGLEFINANCE which fetches current or historical prices of stocks into spreadsheets. So I thought it is totally possible to build my own personal portfolio tracker with Google Sheets. I can register my transactions in a sheet and use the pivot table, built-in functions such as GOOGLEFINANCE, and Apps Script to automate the computation for daily evolutions of my portfolio as well as the current position for each stock in my portfolio. I then drew some sort of charts within the spreadsheet to have some visual ideas of my portfolio. However, I quickly found it inconvenient to have the charts overlapped the table and to switch back and forth among sheets in the spreadsheet. That's when I came to know the existence
