As someone said markets in the short term are voting machines and in the long run weighing machines.
We should give 3-5 years to each company to let sectoral euphoria settle down, valuation mean reversion to kick in and market cycles to play out. Comparing their business and stock performance on a 1 year basis is too short-termish in my view.
For a long term and risk averse investor like me I am happy to be invested in Voltamp and not be discouraged by one-off muted performance when company has done well throughout the market cycles for last many years and handsomely awarded their investors.
