Loan Against Securities (LAS) is a type of loan where a borrower pledges their securities such as stocks, mutual funds, bonds, and other financial assets as collateral to obtain a loan from a lender. LAS allows individuals to leverage their investments and receive immediate liquidity without having to sell their securities. The lender determines the loan amount that the borrower can avail under LAS by calculating a percentage of the market value of the pledged securities. The determination of the loan amount is based on various factors such as the type of security, creditworthiness of the borrower, and prevailing stock market conditions.
