Share prices in the London-listed aquaculture health and genetics group Benchmark Holdings tumbled 22 percent drop in the beginning of the week, following the company's reporting of a weak trading update.
The share-drop led to a market capitalization fall of £67 million (€72.2 million/$80.8 million), from £290 million (€312.5 million/$349.7 million) at market close on Friday, to £223 million (€240.3 million/$268.9 million) following the announcement on Monday.
The London-listed company said challenging conditions across its operations in shrimp, seabass and seabream markets would result in lower sales and profits in the third quarter and full year, sending a negative message to the markets.
As the London Stock Exchange market opened on Monday, share prices in Benchmark dropped to £0.41 (€0.44/$0.49), a 22 percent decrease compared to market close on Friday. The share price dropped another 1.2 percent with the stock market opening on Tuesday.
