Reusing Yahoo's data is not a violation of copyright, especially when applied under a "fair use" case like Leila's paper (because it is merely citing a previous work and creating an original response to it). However, even if her paper did not fall under fair use guidelines, data is not copyrightable because it does not meet the US copyright threshold of "creativity and originality." In fact, even if she used bar charts or other data visualizations from Yahoo Finance, these are not original enough to give Yahoo any sufficient claim of copyright ownership, so Leila need not ask for permission.
