<jats:p>Using a sample of 47 Portuguese and Spanish firms for the period 2010 to 2017, the authors study the relationship between female presence on board and firm's accounting (ROA and ROE) and market-based (MTB and Tobin's Q) performance. They find that women on the board of directors is positively related to firm's performance, as well as the gender of the CFO and the proportion of women on the listed key professionals, when we consider the market measures of performance, not being so consistent for accounting performance measures. Results were sensitive to the performance measure used. The results reinforce the political options of European Commission gender established quotas, revealing that in the Iberian countries these quotas are not being effectively implemented, even if results suggest that women on board in fact exert positive influence over market performance. This also led us to think that financial markets may also react in a positive way when the CFO of the company is a woman instead of a man, despite the sample limitations both in terms of gender and number of firms. </jats:p>
