Some Google, Rohm & Haas Trades Canceled, Nasdaq Says

By Lynn Thomasson

Sept. 30 (Bloomberg) -- Some Google Inc. and Rohm & Haas Co. trades that occurred around 4 p.m. today will be canceled, the Nasdaq Stock Market said.

Trades of Google shares above $425.29 or below $400.52 that were executed between 3:57 p.m. and 4:02 p.m. New York time today will be broken, Nasdaq's regulatory arm said on its Web site. Rohm & Haas trades above $73.20 or below $68.93 during the same time period also will be canceled.

``Participants should review their trading activity for potentially erroneous trades outside the above referenced times,'' Nasdaq said.

Google, owner of the world's most popular search engine, fell as low as $200 at 4 p.m. Rohm & Haas, a chemicals producer, climbed to $100,000 moments before U.S. exchanges closed.

Google's closing price will be adjusted to $400.52, Nasdaq said.

``It's disturbing to watch the number of these things and there seem to be more and more,'' said Laszlo Birinyi, who oversees more than $350 million as president of Birinyi Associates Inc. in Westport, Connecticut. ``We're watching trades more closely.''
