Tokyo rubber lower

Key Tokyo rubber futures gave up early gains and ended down 1 percent on Friday as profit-taking emerged, with many investors waiting to see US corporate earnings and due to uncertainty surrounding Europe's debt crisis. The bellwhether Tokyo Commodity Exchange rubber contract for June delivery settled down 2.8 yen at 277.6 yen per kg. The contract rose to a near one-month high of 279.8 yen before profit-taking emerged.
For the week, the June contract rose nearly 4 percent, the biggest rise in about a month, helped in part by views that the Thai government may intervene to lift prices. Open interest reached the highest in about six months, however, at 26,999 lots.
