This indicates that International Gemmological Institute is gaining traction in a challenging market environment. However, year-to-date, the stock is down 24.49%, contrasting with the Sensex's gain of 4.28%, suggesting that while the stock is currently rising, it has faced significant challenges earlier in the year.
