As many as 50 smallcap stocks logged a double digit rise in their stock prices - in the range of 10-60 per cent last week, outperforming the 30-share BSE Sensex which posted its worst week in over two months. The broader indices comfortably achieved weekly gain of over one per cent, driven by a sharp rally by railway public-sector undertaking (PSU) stocks. 

The frontline indices grappled to gain momentum this week amid global uncertainties and lacklustre earnings by major companies so far. Despite this, railway PSUs have emerged as robust performers, delivering double-digit returns, with some boasting gains exceeding 55 per cent.

Among these, Rail Vikas Nigam Limited (RVNL) witnessed a spectacular rally of almost 58 per cent throughout this week. Today, the stock hit its 10 per cent upper circuit limit, reaching a new all-time high of ₹320.35 apiece, lifting the company's market capitalisation to ₹66,793 crore. Notably, the company gained ₹24,356 crore in market value just this week.
