This document analyzes the stock prices of MRF, India's largest tire manufacturer, over a one month period from November 8th to December 7th, 2012. It shows that MRF's stock price increased by 26.06% over this period, significantly outperforming other tire companies like Apollo and JK Tyre which saw increases of 7.2% and 9.04% respectively. The analysis attributes MRF's strong growth to a major fall in rubber prices on December 5th, which would boost MRF's profits. It recommends either investing in or holding onto MRF shares, as the company appears well positioned to continue gaining if rubber prices remain low.
