Investors in the stock market have been witnessing a significant rally in the PSU (Public Sector Undertaking) bank space. However, market expert Kedar Kadam advises caution while picking stocks in this sector. The recent multibagger rally may not necessarily indicate sustained growth in the future. Investors need to carefully analyze the fundamentals and financial health of individual PSU banks before making any investment decisions. While the sector shows promise, it also carries significant risks. Kadam suggests thorough research and understanding of the sector before making any investment moves.
