1. What is the procedure by which the accuracy of the data inputs is checked? In particular, does the accuracy of data in a table depend solely on the collective effect of perusal and correction by Wikiwealth members?
Model assumptions are found near the bottom of the resources page on wikiwealth. We will try to find a more intuitive spot to place this information.
In general, the assumptions incorporated by wikiwealth are conservative and follow the practicies employeed by Warren Buffett.
I have a similar question: how in general do you establish reliability and accuracy of information?
In addition what is your review procedure, and which quality checks do you establish.
It would be helpful if you could outline your practices in more detail and provide more background on the people behind the project, as well as how you prevent insider information being leaked and attempts on market manipulation and qualifications of people participating in the project.
I like the concept and actually though about a similar site a few months back. However, the quality assurance issues have deterred me for the moment. If would learn more about how you manage quality, I could imagine becoming a contributor and user. So far I remain skeptical of the information being provided.
You have some very good question. Let me answer them one at a time:
1. Reliability and Accuracy: We rely on our in-house talent to establish a base level of quality. To enhance our quality standards, so rely on users to edit, change, and improve textual information. Users notify us of improvements we can make to our quantitative information.
2. Quality Check & Manipulation: Our team reviews every change to the site. This assures quality and filters spam. We do additional research if we suspect manipulation.
3. Insider Information & Leaks: We, unfortunately, can't disclose our procedures for dealing with this type of information. We follow all legal precedence.
4. Background of Team: Our team originates from Duff & Phelp's (http://www.duffandphelps.com/Pages/default.aspx), the leading valuation firm in the world. Our intellectual leaders hail from Harvard and NYU Stern.
5. Contributions: Since we review every contribution, we appreciate any person who would like to share their unique knowledge to improve the quality of the research on WikiWealth. Use WikiWealth to record your notes on your favorite companies. Users will help improve on your initial thoughts and we will all benefit from better investment research.
6. Skeptical: Absolutely all of our information is transparent, so if you suspect anything is wrong, you have our full analysis to investigate the quality of our work. Additionally, you can experiment with our valuation models to create your own unique conclusions. We simply provide a forum to share information and some advance models to help with your investment picking.
We hope this helps. Send any additional investment questions as they arise.
