Weak markets over the last few days have also come with significant volatility.. The market environment also impacts smaller stocks as traders and investors eye shorter term plays, and plays in stocks where their impact on share price is disproportionate. This has been the case with Roto Pumps, which has seen a year high in the last week even as markets fell overall.

Share price of the stock jumped over 40% in the past week, significantly above the usual range the share price trades in. Clarifications requested by BSE yielded no additional information from company management.

This was seen a couple of times before, including December 2014, when the share price of the company hit an all-time high before falling back.
