Petru, what we do is first of all look at historical and current financials of compaies that we think, from a macro perspective are likely to do well. Once identified, we isolate companies that meet particular financial ratios that we look for (very similar to the factors Buffet looks at). Then we get a more holistic in further considering the company. We do media searches, Google searches, (not just on the company but on its management). We use webb-site.com for some data, bloomberg, Quamnet, etc. We are based in Asia and also check "on the ground". That means speaking to actual customers and people in the industry. It means visiting stores, sampling goods, speaking to sales staff, speaking to people in similar industries, and where possible also speaking to people in relavant Government departments and/or with Government connections. We do also try to speak to company management directly, both by phone, by email, and where possible visit in person. All of these factors ultimately play in a role in the small number of companies we identify to invest in.
We entirely agree with you - some of these China stocks have fraud issue, and even those listed on the Hong Kong (which are the ones we consider due to higher listing standards) are not immune. TO minimize this risk, we stay away from any company with management that has a bad history (or in some cases fake qualifications). Again, Webb-site.com has a wealth of resources here. We also closely examine any negitive or concerning news that might emerge about a company, and if it smells bad we exist quickly and move on. We also look at the company auditors and give preference to companies audited by one of the Big Four. Again, this does not render is immue to fraud, but its a variable we consider. Finally, we invest in a number of companies, not a single one. So, if we itentify say 10 companies that we expect to double this year, each with a 10% allocation, we might expect 2-3 to rocket up and more than tripple, some to double, some to remain flatish, and perhaps one dud, but overall still a very nice profitable gain on our total investment.
