Singapore shares fell at the start of the week, echoing broader Asian markets despite encouraging U.S. jobs data on Friday that showed a recovery in the world’s largest economy.

The benchmark Straits Times Index fell 0.5% to 3,196, while MSCI’s broadest index of Asia-Pacific shares outside Japan was down 0.4%. Noble Group was the worst performer on the index, edging down 3.5% at to $1.235, shedding some of the gains it posted last week. Last Wednesday China’s biggest grain trader COFCO Corp said it plans to buy a majority stake in the Singapore-listed commodities firm’s agribusiness for an initial US$1.5 billion ($1.9 billion).

Among small caps, shares of Annica Holdings plunged 40% to an all-time low of 0.009 after the company said late Friday it was the subject of a probe by Singapore’s Commercial Affairs Department for possible trading irregularities.

The company is the latest in a series of penny stock firms that saw their share prices plummet after being investigated by the CAD on possible breaches of the Securities and Futures Act.
