Fenner's Interim results, less than 1 month ago, said that both divisions were experiencing strong trading, and the growth drivers in their end markets reamined positive.
My feeling is that the recent drop in their share price is a great buying opportunity.
There may be a short term weakness in the mining industry (after all it is more prone to swings of fear & greed than any sector with the possible exception of the banks) but taking a long term view. The world's population is continuing to grow, and quality of life is continuing to increase. Both trends point to a long term increase in demand for reaw materials of all sorts. Of course if we had a major war to reduce the population that may change things, but weaponry has a great demand for metals; and wars always result in major rebuilding projects.
Either way I think there is a strong long term case for the mining sector.
