Liquidity is correlated to trading volumes - so the more people exchange shares of your company, the quicker you can find a counterpart. Investors accept lower returns if they can get their money back whenever they please, so a liquid investment vehicle is advantaged. Ceteris paribus, volatility is negatively correlated to trading volumes: if your shares are only exchanged twice a week (actual trading volumes for a small company on some exotic exchange) the price variations will inevitably happen in large steps, which does not reassure investors. And if the company is not publicly traded, who knows what the price of the next transaction will be ? A lively market for an investment vehicle opens the possibility of derivatives, which are valuable to investors interested in the company but whose appetite for risk is limited. So if your company's shares trade has derivatives, it makes them more attractive.
