Undervalued companies - Possibilities for portfolio inclusion

Hi all there are quite a few seniors and good Analysts here and I would like to query if my below picks are good for small cap investment. Relative noob here.
I have chosen these stocks after some screening and possibly market is still discounting them.
Some of them have good BV, others have grown stellar fashion

  • VLS FINANCE
  • STANROSE MAFATLAL FINANCE
  • SARASWATHI COMMERCIAL
    -NAHAR CAPITAL
    -FIRST SOURCE SOLUTIONS

Grateful for any logic with the feedback to sharpen my own skills at picking stocks.
