Sprott Upgrades RecommendationWell, this is interesting. Despite the announced delays in production (sales) and the anticipated delay in margin improvement, Sprott has upgraded RailPower from a "Market Perform" to a "Speculative Buy". Sprott's research note suggests that RailPower's announcement of yesterday only made a minor difference to its (Sprott's) anticipated sales and margin targets for RailPower and the upside for RailPower shares($4 in Sprott's estimate) was significantly more likely to occur than the downside, ($1.80 in Sprott's estimate). Hence, the note concludes that current share price represents a buying opportunity.
