johnrxx99,
Nothing to get too worried about, but they are reliant on the price and demand for Molybdenum and Tungsten, amongst others. Plus, I'm always a little wary of investing in Israeli companies, based on past experience. Therefore, I wouldn't expect these to trade on a racy forward PE.
I do expect commodity prices to stay strong in 2006 though, so I think there could still be a chance of £3+. However, the risk/reward balance now suggests that they are a 'hold' rather than a strong buy at the current price.
Good Luck.
Cheers,
Chris
