// monsa vs portfolio visualizer
Monsa and Portfolio Visualizer, where they overlap and where they do not.
Portfolio Visualizer is about how a portfolio behaves. Monsa is about whether its contents match your rules.
What Portfolio Visualizer is for
Backtesting, factor analysis, asset allocation and optimisation models, mostly at the level of an allocation rather than an individual holding.
Monsa holds the rules you wrote down and checks your holdings against them every night.
The two operate at different altitudes and on different questions. Portfolio Visualizer works on allocations and history; Monsa works on the companies you hold now and the criteria you set for them. Neither says anything about the other's subject.
Side by side
| What you want to do | Portfolio Visualizer | Monsa |
|---|---|---|
| Analyse an allocation | Extensive, with a long history of models. | Not offered. Monsa has no view on allocation. |
| Work at the level of an individual company | Not the focus. | The only level it works at. |
| Keep written criteria and check holdings against them | No. | Yes, nightly. |
When you do not need Monsa
If your questions are about allocation and history rather than about individual companies, this is the wrong tool for them.
Monsa is also not a broker, does not place trades, and never says what to buy or sell. The other comparisons say the same thing about different tools, and a spreadsheet gets further than most people expect.
Rules written down while you still remember why you bought something survive the moment the price argues with you.
