Hi Allen.. Kindly list your recommendations for best introductory material (books/others) on finance

sure! "finance" is a pretty large topic, and most of what I know I learned on the job, so don't take this as exhaustive by any means, but some I enjoyed: Common Stocks and Uncommon Profits by Phil Fisher, The Alchemy of Finance by George Soros, Latticework by Robert Hagstrom, Capital Account by Edward Chancellor, all the Buffett Shareholders, all the Saber Capital blog posts, all the Jerry Neumann (Reaction Wheel) blog posts.
