Can Someone Please Guide Newbie's Like Me

I was looking at Affordable Robotic & Automation Ltd - Niche businessThere is a lot limit of 1600 shares could fellow value pickrs shed some light on why that’s so?

Numerous other shares (penny stocks mostly) seem to have similar limits.

  • Are these limits arbitrary?
  • Is there a threshold of market cap or any other parameters after which shares will be traded as one or more shares
  • What are the implications for smaller investors of investing in such lots apart from larger capital getting locked?

P.S. This is my first query on the forum, apologies if I violated any guidelines or best practices.
