I like midcap stocks because they have comparatively lower risk. They have already proven themselves (that's why they are not micro cap ) and they have big room to run.

Stone India

Stone India is a railway engineering company based in Kolkata. Their key product is Railway brake system. They have product license from WABTEC that's a us based company with patented air brake systems for locomotive. Demand from Railway will continue to grow and I think there is no lack of business for Stone India. They recently started working with railrunner another USA based company for a unique type of rail  system specially for cargo movement. That is really a good start.
