Summary:
This paper examines the implications of noise trading (the Shleifer-
Summers-Men-khoff hypotheses) in the interbank foreign market in Korea, using
the survey method. The results confirm that the noise trader approach is widely
accepted and its implications are strongly supported in Korea. Firstly, noise
trading appears to be widely and repeatedly used. Traders appear to favor noise
trading rather than fundamental one, with 72 percent of the respondents being
classified as noise traders. Secondly, the implication of the efficient market
hypothesis that noise traders will be eliminated because of their inferior
strategy receives little support. Thirdly, the implication that noise trading
would be a second-best strategy, which is easier and cheaper to use, is not
supported. Finally, noise trading appears to be used because of its
self-fulfilling character to some extent.
To be successful in the
Korean foreign exchange market, it is important to employ not only fundamental
but also noise information such as technical analysis, trading volume, positions
already held, investor sentiment, advice of opinion leaders and statement of
government officials.
