That is spectacular performance by any standard, but it is especially noteworthy when you consider that the broad Bangkok market (as represented by the SET index) is up only 35%.
Furthermore, the lion's share of the portfolio's returns have come from stocks that U.S. investors will have a hard (or impossible) time accumulating. For example, PTT Chemical is extremely thinly traded, yet is one of the top-performing stocks in the world this year and the top holding in THD, with 10.77% of the overall portfolio. Likewise, Bangkok Bank is not a highly liquid ADR, but with 9.23% of THD's holdings wrapped up in this stock, U.S. investors are unlikely to get exposure in any other form.
In fact, even moderately widely traded ADRs only account for 25% of THD and about 25% of its overall YTD performance. In theory, you could have replicated THD's gains by just buying these six stocks, but a six-stock basket is not exactly highly diversified when you consider that the other 80 stocks in the portfolio provide much broader access to Thai banks and consumer companies.
Most notably, construction and hospitality stocks are missing from the ADR list. Both of these sectors have been dead money this year -- on global recession fears and the spring political upheavals in Bangkok, respectively -- and so both could be due for a rebound. If so, ADR-only investors would be out of luck.
One only moderately liquid ADR that might be worth fighting for: Charoen Pokphand Feedmill (OTCPK:CPOKY). This stockyard operator does not trade all that often in the United States, but is up over a staggering 200% so far this year, largely due to the prospect of increased demand for meat in China and throughout Asia:
