This article came to my attention because it is listed at Copyright problems. However, rather than address the copyright issues, which might entail a rewrite, I think it would be better to delete the article. My rationale has four aspects:
WP:NOT#DICT This is Wikipedia not Wiktionary, and the article consists solely of two sentences purporting to define a financial term
It is wrong. Despite being stolen from a business directory, it isn't even correct. While it does have something to do with yields, it isn't a probability, and the definition covers a broad range of activity, not all of which is precisely convexity risk.
Already covered. Although not referenced, the article Bond convexity covers the topic in an more encyclopediac manner. (Arguably convexity risk is a broader term than bond convexity, but the broader term is better covered in Convexity (finance), while this definition is more narrowly related to fixed income securities.)
