I don't invest in the Korean stock markets for a number of reasons-extreme volatility and difficulty to access the markets/customer service/language barrier issues (said in previous comments from others on this thread). However, I do invest in the American stock markets in the USA. Also, there, you have access to a number of ADRs (American Depository Receipts) that track the biggest and best Korean companies like LG, Samsung, Posco Steel, etc. Dealing with an American online broker is really easy from here in Korea. Also, since many of us are paid in Korean won, I suggest learning to watch the Korean won currency vs. the dollar and looking for opportune times to exchange around 1100-1120 range. I am no expert, but from studying the KRW charts it appears that the won is having a lot of difficulty breaking through the 1100 level. Also, compared to other currencies in the world, the Korean won is one of the most volatile and therefore I don't feel comfortable keeping my all of my current savings in the Korean won. Since all of my future earnings this year will be paid in the KRW, I like to minimize my risk by getting mostly back into the US dollar. The world currency markets are an extremely complicated mechanism but if you have the time and inclination, try learning how they work and what moves them and you will be able to time your money transfers at a decent time. One more annoying thing about the Korean won is the potential risk from North Korea rattling the markets.
