diesel vs palm oil spread has gone ballistic

Increased price and turnover in MBT prompted me to look at this stock again. Whilst biodiesel stocks have been disasters in recent months, it is worth noting that palm oil prices have fallen 17% since the highs of February and diesel has gone up by 42% (as measured by Singapore Gasoil); Also, MBT is forecasting an EBITDA for year ending June 2008. This is mainly interest income but spread of diesel/palm oil certainly looks encouraging for next year. Any views?
