Broader Market Context: In the short term, Deepak Chemtex's performance has lagged behind the Sensex, which has gained 1.58% over the past week, while the stock has only increased by 0.74%. This underperformance in the short term may be attributed to the stock's opening gap down and lower trading volumes, indicating a cautious sentiment among investors. The liquidity of the stock remains adequate for trading, but the decline in delivery volume suggests a potential lack of confidence among investors, which could impact future price movements.
