I agree partially.. A public companies growth has much more to do with sales than market cap....market cap should follow. If a company the size of SIAF is paying a dividend rather than retaining earnings for growth, then they're likely going to have to sell shares and dilute the stock when growth/investment opportunities present themselves, which will shake the very investors you're talking about keeping.
Maybe there is a place for a small dividend, but high growth companies should have increasing sales thus a need for more capital to support those sales. Liquidity in the secondary markets make little difference to a company that is already well capitalized from retained earnings.. If they're well capitalized which helps to grow sales, the liquidity will be there. What you're saying is kind of like the tail wagging the dog, IMO.
