本文透過蒐集1994年至2011年台灣上市、櫃公司的資料,探討公司若具有股價低於淨值、面額或同時低於淨值及面額的特徵,對於其未來獲利能力變動是否有正向的影響,並且探討規模因素是否對於這些群體未來的獲利能力變動有額外的影響。實證結果顯示,在控制獲利能力、資本結構及償債能力、資金來源、公司規模及產業的因素後,股價低於淨值及股價低於面額的特徵對於未來獲利能力變動有著顯著正向的影響,支持本研究假說,而股價同時低於淨值及面額的特徵雖然呈現顯著負向影響不支持本研究假說,但該特徵對於未來獲利能力變動的整體影響大致上仍是正向的,且以上影響至少在未來三年都有顯著的效果,表示股價低於淨值、面額或同時低於淨值及面額的公司雖然當期營運表現不好,但未來獲利能力是會逐漸改善的。然而本文所測試的規模因素大致與過去文獻結果一致,表示公司若為小規模對於未來獲利能力變動有正向影響,但實證結果顯示規模因素與股價低於淨值、面額或同時低於淨值及面額特徵的交乘項,對於未來獲利能力變動並無一致且顯著的影響。透過本研究所呈現的結果,可以作為投資人在作投資決策時的參考指標,且希望藉由本文呈現的結果,能夠減少投資人容易對於這些公司的未來表現過度悲觀的情形,同時也希望可以促進相關政府部門去思考哪些措施能夠幫助這些公司重拾投資人的信心及維持市場有效率地運作。
This paper examines the effect of the characteristics of price below book value, price below face value and price below both book value and face value on changes in the future accounting profitability of Taiwanese listed firms from 1994 to 2011. The results show that the characteristics of price below book value and price below face value are positively associated with changes in the future accounting profitability. Although the results show that the characteristic of price below both book value and face value is negatively associated with changes in the future accounting profitability, the overall effect of this characteristic is positive. This study also examines the effect of the size factor on changes in the future accounting profitability. The results show that the size factor is negatively associated with changes in the future accounting profitability consistent with prior research, but this study doesn’t prove that the interactions of the size factor and these characteristics have the incremental effect on changes in the future accounting profitability. This study indicates that the characteristics of prices below book value, prices below face value and prices below both book value and face value are good indicators for investor to form a value stock portfolio. This study also can persuade investors not to make excessively pessimistic expectation about these companies’ future accounting profitability and promote government departments concerned to take action to keep stock markets to work efficiently.
