Earnings miss triggers sell-off

Dexerials Corporation reported first-half earnings of 12.639 billion JPY, or 72.68 JPY per share, RTT News reported. This compares with 13.410 billion JPY, or 76.39 JPY per share, in the same period last year. The company’s revenue for the period also fell 2.6% to 55 billion JPY.

The company did not provide a specific reason for the earnings decline in the summary provided by RTT News. None of the reports reviewed by Falling Shares gave a reason for the sharp fall in the share price beyond the earnings data.

Stock underperforms market peers

By Falling Shares' measure, almost all of the move was company-specific. The stock fell 15.5% on company news, while the broader market, represented by the Nikkei 225 which dropped 0.8%, contributed just 0.8% to the decline.

The stock has struggled recently, falling 12.8% over the past five days and 36.8% over the last month. It is now 56.7% below its 52-week high of 5,228 JPY.
