The present paper explores the possibility of forecasting company liquidity based on testing the coefficient of variability. Secondly, it analyzes static and dynamic liquidity measures to ascertain which are better at prediction in the traditional and technology-based sectors. It was assumed that the cash conversion cycle should be the more predictable measure and forecasts using it should be more accurate for traditional companies, but the CCC has turned out to work better for technology-based businesses listed on the Warsaw Stock Exchange. Poland is an example of a developing market that has undergone a transformation and has not been dramatically affected by the crisis, and we believe that our research may reveal some liquidity-related economic patterns applicable not only to other in-transition and developing countries, but also to countries facing economic problems. The study was conducted on the non-financial companies listed on the WSE in the period 1997 - 2010.
