Why is Renaiss. Global falling/rising?

As of 12-Sep, Renaissance Global Ltd's stock price is currently at 117.45, reflecting an increase of 1.75 or 1.51%. Today, the stock has outperformed its sector by 1.8%, reaching an intraday high of Rs 120, which is a 3.72% rise. Over the past week, the stock has shown a return of +4.03%, and over the past month, it has increased by +11.22%. Despite this positive short-term performance, the stock has a year-to-date decline of -31.73% and a one-year return of -7.45%. The company's return on capital employed (ROCE) is at 7.1, indicating a very attractive valuation, and the promoters have increased their stake by 3.52%, suggesting confidence in the company's future. However, the stock has also seen a significant drop in investor participation, with delivery volume falling by 58.21% against the five-day average.
In the broader market context, the Sensex has increased by 1.48% over the past week and 2.08% over the past month, indicating that while Renaissance Global Ltd is performing well relative to its recent history, it is still underperforming against the benchmark on a year-to-date basis, where the Sensex has gained 4.82%. The stock's long-term fundamentals appear weak, with an average ROCE of 8.16% and poor growth in net sales and operating profit over the last five years. This consistent underperformance against the benchmark over the last three years may contribute to investor caution despite the recent positive movements.
