A lot of portfolio back tests (and their resulting charts) are just silly. Any moron can go into a spreadsheet to find what worked best in the past (especially when cherry picking dates). But it takes some real thinking to work out a strategy that can deal with future unknown risks. You can’t optimize for returns going forward because you don’t know what those returns will be. So anyone designing a portfolio based only on what worked best in the past is making a major tactical error with their investments. A mistake that could destroy a retirement plan.
Most of us are familiar with the program known as Microsoft Excel, which is one of the programs that is part of the Microsoft Office Suite. To many, it’s a simple database program that allows you to create spreadsheets for whatever you may need. But if you take the time to learn the ins and outs of this program, you will find it is much more useful. By thoroughly learning this robust software, you can set yourself up for not only success in your job but at home as well.
Third, building the right kinds of collaborative applications requires some skill and understanding how and what kinds of data are shared. How many people are going to be adding/changing records to your database? How many just want to do queries and reports? And how do you prevent conflicting updates?
There are many such forms that will help you plan and organize your life. The monthly budget spreadsheet is another example of a spreadsheet that will help you to organize your budget for the month. At the end of the month you can go through these spreadsheets and analyze as to what is eating up most of your expenses. This can help you to plan and save on the budget for the next month onwards.
Is your job dealing with more and more paper work all the time? If you are an office clerk or reports assistant or even if you are a manager you will have to send reports on a monthly basis and more often they will have to do with comparing old and new files as well as updating them. To compare spreadsheet reports, you will have to understand the values being given and consolidate it with any changes made for a certain period of time. If you will be dealing with several files here to compare, you may find this a very daunting task. However, knowing that there is a tool you can use to make this task easier for you is a great relief.
This is why I find it so absurd when some analyst or pundit claims that an asset like gold is ”worthless” in an investing portfolio because of some biased spreadsheet work they did. I wonder if these people have ever gotten far enough away from their spreadsheets to see how the world markets really work? Having some portfolio insurance like gold around is a really splendid idea. YES, the Forever Portfolio holds gold, silver and displays a good record with other assets likes stocks (mainly ETFs), bonds and cash. But what in history suggests this is not a good idea? Show me the flaw! Show me the data? It doesn’t matter what your chart is showed worked best over a particular time period. The fact is that concentrating your bets is dangerous, and sometimes your stocks and bonds don’t payout on your timetable. This is just how life works. I am finding out more each day. Diversifying a little bit is prudent.
There are two information-related walls that a young company hits while trying to grow. The first wall is what I call ”spreadsheet suffocation.” It is that stage of information sharing pain that causes people to start cussing. Where did you save the Johnson calculations? Who has the orders spreadsheet locked? Where did my new inventory list go? Did someone write over it? There was 2 days work in that spreadsheet!
