Talk:SABR volatility model

Opening heading
The formula is wrong!!! That is not a proper copy from the original article formula!

Previous comment
The formulas in the article are, in fact, the original formulas written in a somewhat different but equivalent form. — Preceding unsigned comment added by ProfessorTarantoga (talk • contribs) 02:01, 5 June 2011 (UTC)

special case of ATM
This article should have the special case of ATM, the general formula blows up when strike=future

Previous comment
Good point, one cannot simply substitute strike = forward. The ATM case has to be handled as the limit strike -> forward, which can easily be calculated using l'Hopital's rule. This is important when one implements the formuala in computer code (which will otherwise blow up).

SABR Volatility Model → SABR volatility model –

Per WP:MOSCAPS ("Wikipedia avoids unnecessary capitalization") and WP:TITLE, this is a generic, common term, not a propriety or commercial term, so the article title should be downcased. Lowercase will match the formatting of related article titles. Tony  (talk)  23:57, 15 December 2011 (UTC)
