Seoul shares fall, positions squared before Jackson Hole
* Index down 1.4 pct in low volume
* Halla Climate rises 2.9 pct on buyout hopes
SEOUL Aug 30 (Reuters) - Seoul shares fell 1.4 percent on Thursday morning as investors squared positions ahead of the Jackson Hole, Wyoming meeting of central bankers that many hope will provide further clues about the potential for further U.S. stimulus.
"The main board is sagging due to sell orders from local institutional investors and program trading, in the relative absence of trading volume before the speech at Jackson Hole," said Kim Young-joon, an analyst at SK Securities.
"Program selling from foreign investors appear to be natural profit-taking before a key event."
