Why is TCI Finance falling/rising?

As of 20-Jun, TCI Finance Ltd is experiencing a decline in its stock price, currently at 17.05, which reflects a decrease of 0.89 or 4.96%. The stock has been underperforming, having fallen consecutively for the last two days with a total return decline of 9.69%. Despite this recent downturn, TCI Finance has shown strong performance over the past month with a return of 35.96%, and it has outperformed the benchmark Sensex over various periods, including a 27.33% return over the last year. However, the company faces challenges, including a negative book value and weak long-term fundamental strength, as evidenced by a significant decline in net sales and a risky trading position compared to historical valuations.
In the broader market context, TCI Finance's recent performance contrasts with the Sensex, which has gained 1.59% over the past week. While TCI Finance has outperformed the benchmark in the long term, its current struggles highlight a divergence in short-term performance. The stock's recent underperformance, particularly in the context of a negative book value and poor long-term growth prospects, suggests that investors may be cautious despite the company's past successes.
