My favorite SARS play is APT. so many asians are seen wearing their masks now. One airline is starting to offer the masks to all crew and passengers. I think this is just the start. masks aren't a definite defense but with the disease being transmitted by droplets like in a sneeze, if I lived in an area that had the disease I know I would be wearing a mask. This is just a momentum play but I think it can run for a lot longer. I'll wait til they are on cnbc and see a big jump. Give it a week or two. that will be the sign of a top.
