However, the Securities and Exchange Board of India (Sebi) has not found any irregularity on the part of the company.
L&T Finance Holdings' scrip declined over one per cent to end the day at Rs 76.15. After opening at Rs 77, shares of the company had touched an intra-day low of Rs 75.60.
However, shares of the parent company Larsen & Toubro registered marginal gains to close at Rs 1,688.70.
In an interim order passed yesterday, Sebi had barred Hong Kong-based hedge fund manager Factorial Capital Management from the Indian securities market after finding its Cayman Islands-based fund - Factorial Master Fund - to have allegedly profited through 'short-selling' in shares of L&T Finance Holdings on the basis of unlawful access to insider information about the company.
