risk in the market.<\/p>\n<h2 id=\"how-a-volatility-smile-forms\">How a Volatility Smile Forms<\/h2>\n<p>Several forces shape the smile:<\/p>\n<ol>\n<li>Demand for downside protection lifts OTM put IV<\/li>\n<li>Demand for upside bets lifts OTM call IV<\/li>\n<li>ATM strikes see balanced positioning<\/li>\n<li>Market makers price extra risk into tails<\/li>\n<\/ol>\n<p>These forces combine into
