There are a number of interconnected factors that lead to the success or failure of any business so it is usually considered an impossible task to predict whether a company will sink or swim numerically but researchers in Taiwan using the principles of evolutionary biology say they have devised an approach to spotting when a company is likely to fail.
Ping-Chen Lin of the National Kaohsiung University of Applied Sciences in Kaohsiung and Jiah-Shing Chen of the National Central University, Jhongli, in Taiwan, also explain how their metric of the financial status of any company can be of interest not only to its owners and employees but to a range of creditors, stockholders, banks, and individual investors.
The researchers have now borrowed some of the principles of evolutionary biology to come up with a computer algorithm to make such predictions possible. They feed different variables, such as earnings per share, liabilities and net income, into their genetic-based hybrid algorithm, which assigns a weighting to each value.
The output of the algorithm is a new set of variables that are then selected for how well they fit the next set of financial results from the company. Those that fail are discarded, or reduced in weight, and those that match the actual results more closely are fed back into the algorithm for the next round.
By using actual data from successful and failed companies and feeding this into the algorithm the researchers build up the fittest set of variables and weightings. This allows the algorithm to evolve so that it can then predict the financial future of any given company based on current income and expenditure, and tax obligations.
The team has blind tested the predictive power of their system on several companies successfully. "Our experimental results show that this hybrid approach obtains better prediction performance than when using a single approach effectively," the researchers say.
