<p>It would do no harm to add a clarification inside the tag wiki, such as:</p>
<blockquote>
<p>Tag usage</p>
<p>Do not use this tag for <a href="http://en.wikipedia.org/wiki/Beta_(finance)" rel="nofollow noreferrer">Beta</a> as measurement of how much an asset return can be predicted by a benchmark (finance context). Consider using the tags <a href="https://stats.stackexchange.com/questions/tagged/finance" class="post-tag" title="show questions tagged &#39;finance&#39;" rel="tag">finance</a>, and/or <a href="https://stats.stackexchange.com/questions/tagged/beta-risk" class="post-tag" title="show questions tagged &#39;beta-risk&#39;" rel="tag">beta-risk</a>, instead.</p>
</blockquote>
<p>This was just a rough suggestion (both wiki amendment and beta-risk tag).</p>
<p>It seems there are no current threads labelled <a href="https://stats.stackexchange.com/questions/tagged/beta" class="post-tag" title="show questions tagged &#39;beta&#39;" rel="tag">beta</a> outside the beta-distribution concept.<br />
This is why I am suggesting to add the clarification inside the wiki and not inside the excerpt (but no objection using the excerpt, if one prefers).</p>
<p>Doing a research by <a href="https://stats.stackexchange.com/search?q=%5Bfinance%5D+beta+is%3Aquestion">[finance] beta is:question</a> it returned 4 questions. I believe the newest one is a candidate to place the new tag, if it is the case.</p>
<p><a href="https://stats.stackexchange.com/questions/67198/can-i-run-a-regression-where-dependents-are-coefficients-from-other-regression-a">Can I run a regression where dependents are coefficients from other regression and independents are R squared from these regressions?</a></p>
