Sigachi Industries' share price dropped to a two-year low, falling over 10% on Monday. This decline is attributed to the arrest and remand of its Managing Director and CEO, Amit Raj Sinha, in connection with an industrial blast case. The arrest has raised concerns about management stability and reputational challenges. The company has appointed Lijo Stephen Chacko to oversee operations during this period. The stock has seen a significant increase in trading volume and a year-to-date slump.
