Russian oil producer Exillon Energy (EXI) gushes up 19% to 185.6p after putting itself up for sale following a number of preliminary approaches. Back in July (30 Jul) the firm, which used to be a constituent of the FTSE 250, announced it was subject to bid interest from its founder, Kazakh businessman Maksat Arip.

Ukraine-based iron ore producer Ferrexpo (FXPO) has paid $80 million for a 14.4% stake in Brazilian iron ore miner Ferrous Resources which has a 4 billion tonne reserve and resource base. Ferrous has failed on two occasions to list on the London stock market. BHP Billiton (BLT) has been linked to takeover talk in the past with rumours of a $3.2 billion deal. Brazilian miner MMX has also been linked with merger talks a few years ago. Ferrexpo dips 0.7% to 182.4p on today's news.

A short and sweet update flags significant improvement in outlook for education software supplier RM (RM.), sparking a near 20% spike in the shares to 112p.

Airline catering provider Journey (JNY:AIM) rises 5.1% to 133.5p after interim pre-tax profit increased more than three-fold to £937,000 from £254,000 a year earlier. The £16.3 million cap has £4 million net cash and the results have prompted house broker N+1 Singer to upgrade full-year pre-tax profit by £200,000 to £1.8 million. We remain very sceptical of the business model which is extremely easy to copy. Journey uses local restaurants to make the food, thereby avoiding the need to invest in big food preparation centres.

Chinese branded sportswear maker Naibu Global (NBU:AIM) jumps 8.8% to 68p after posting strong half-year figures.

We said to get out of the stock last month.
