June 12 (Reuters) - Adidas shares fell 1.5% on Wednesday on expectations that one of the German sportswear firm's top shareholders, Groupe Bruxelles Lambert (GBL), was preparing to sell a portion of its stake, three traders said.
Belgian investment firm GBL was placing a tenth of its 7.5% holding, or 1.37 million shares, at 257.75 euros ($292.11) on the market for sale, a 1.7% discount to Tuesday's closing price, the traders added.
GBL and Adidas, whose shares hit record highs on Tuesday, were not immediately available for comment.
At 0801 GMT, Adidas shares were down 2% at 256.9 euros and lagging the broader DAX index, which was down 0.3%.
GBL, founded by Belgium's richest man Albert Frere, who died in December at the age of 92, first invested in Adidas in 2015 with the purchase of a 3% stake.
GBL also holds stakes in some of Europe's biggest companies, including Pernod Ricard, LafargeHolcim and Total.
