Why is Oil Country falling/rising?

As of 30-Jul, Oil Country Tubular Ltd's stock price is currently at Rs 88.85, reflecting an increase of Rs 2.75 or 3.19%. Today, the stock has shown a positive trend, gaining after three consecutive days of decline and opening with a significant gap up of 6.17%. It reached an intraday high of Rs 91.41. Despite this upward movement, the stock has underperformed the benchmark over the past week and month, with declines of 1.93% and 2.97%, respectively. However, the company has reported positive results for the last four consecutive quarters, with net sales growing by an impressive 337.41% in the latest six months, and a high inventory turnover ratio of 4.00 times. Nonetheless, concerns about long-term fundamental strength persist, particularly with a return on capital employed (ROCE) of 0% and a high debt to EBITDA ratio, which may contribute to the stock's volatility.
In the broader market context, Oil Country's recent performance contrasts with the Sensex, which has seen a smaller decline of 1.50% over the past week. The stock's year-to-date return of 29.92% and a remarkable 99.48% return over the past year indicate strong performance relative to the benchmark's 4.28% gain in the same timeframe. However, the stock's liquidity is noted to be adequate for trading, despite a significant drop in delivery volume, which fell by 54.34% against the five-day average. The increasing proportion of pledged promoter shares, now at 61.15%, raises additional concerns about potential downward pressure in a declining market, highlighting the risks associated with the stock's current valuation.
