backtesting
I have been using the Back test facility for some time now and would offer some observations and comment that I feel might improve the understanding and use of this tool.
There is a possibility that members could be confused between the terminology of a HOLDING in a portfolio and the number of positions within a holding.
You use the term POSITION in the MORE SETTINGS tab where I think you mean HOLDINGsWhen the options are positioned NOT to restrict further investments in a company, multiple positions can arise in one HOLDING. A breakdown of the portfolio clearly shows the difference, but the phrase is misleading in the settings options
Whilst the settings allow for a restriction on the INDUSTRY or SECTOR of a holding, there is no restriction on the overall % of a holding in the portfolio. Might it not be a good idea to allow members to set a max parameter for a holding?
I have found that when I do not restrict multiple purchases of a particular stock, it can distort the portfolio quite significantly by becoming the largest holding and conceivably the majority holding of the resultant back tested portfolio.
It is not a position I would like in real life and I think the back tester ought to reflect my preferred stance in such circumstances.
- I have a number of friends who participate in Investor Clubs and only meet once a month. I think they might be more inclined to trust and use VV7 information if they could see that VV7 can deliver good selections when it can mimic the way their clubs trade.
That would involve back testing having an option to dealing once a month or other intervals of time, rather than daily as is the case when running currently running back tester. This would allow them to develop strategies they can feel comfortable about using the info that VV7 provides.
Currently they some of them dismiss its usefulness, because they do not want to trade as often as the system suggests they ought.
I appreciate it is not a trivial matter to consider changing terminology or layout of the Back Tester’s options, but I hope you can see why I am making these points.
