UBS executives have sold millions in shares since the Swiss bank announced its second quarter results, according to filings on the SIX stock exchange website.

Since the start of September, UBS shares worth more than 14 million Swiss francs ($15.68 million) were sold in five transactions by executive members of the board of directors or members of senior management.

The sales come in the aftermath of the bank's second quarter results, which saw shares trading at highs not seen since 2008.

UBS declined to comment.
