Every asset moves; some will move fast, and some will move slow. RV is a statistical measure derived from historical price movements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"line-height:1.8;text-align:justify\">Just see an example: if the Nifty 50 has swung violently over the last 30 days, its realised volatility will be high. Conversely, if the index has been trading in a narrow, stagnant range, the RV will be low.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"line-height:1.8;text-align:justify\">The reason is that it is computed directly from past prices; realised volatility is backward-looking. It represents past price movement based on historical data.<\/p>\n\n\n\n<h2 id=\"aioseo-what-is-implied-volatility-7\" class=\"wp-block-heading has-text-color has-link-color wp-elements-0e8f5d9bb3481f21795a0787c2a18c22\" style=\"color:#023368\">What is Implied Volatility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"line-height:1.8;text-align:justify\">If realised volatility is the rearview mirror, then <strong>implied volatility (IV)<\/strong> reflects market expectations of future price movements. It is the market&#8217;s expectation of how much an underlying asset will move in the future. Unlike RV, IV is derived from the current market price of an option.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"line-height:1.8;text-align:justify\">IV reflects market expectations of potential price fluctuations because it&#8217;s a forward-looking metric. If investors expect a major event like an earnings report, budget announcement, or geopolitical crisis, they bid up the price to protect themselves.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"line-height:1.8;text-align:justify\">But how can we calculate it? Remember that you won&#8217;t find IV by looking at the stock price chart; it involves using an option pricing model such as the Black-Scholes model. By plugging in the current option price, the <a href=\"https:\/\/navia.co.in\/ipo-account\" title=\"\">stock<\/a> price, time to expiry, and interest rates, the model solves for the volatility level required to justify that option&#8217;s price.<\/p>\n\n\n\n<a href=\"https:\/\/open.navia.co.in\/index-navia.php?utm_source=organic&amp;utm_medium=blog&amp;utm_content=options_volatility_CTA\" target=\"_blank\" style=\"display:flex;width:100%\"><img decoding=\"async\" src=\"https:\/\/d1l8l3rp33cdzs.cloudfront.net\/images\/naviacee\/Open-free-demat-account%20%28blog%29%20%281%29.gif\" width=\"80%\" height=\"auto\" style=\"border-radius:10px;margin:5px auto\" \/><\/a>\n\n\n\n<h2 id=\"aioseo-comparison-implied-volatility-vs-realised-volatility-11\" class=\"wp-block-heading has-text-color has-link-color wp-elements-b7b9f44d53e7258b1ec19a1947a2d0c0\" style=\"color:#023368\">Comparison: Implied Volatility vs. Realised Volatility<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Feature<\/th><th>Implied Volatility (IV)<\/th><th>Realised Volatility (RV)<\/th><\/tr><\/thead><tbody><tr><td>Perspective&nbsp;<\/td><td>Forward-looking: It reflects market expectations of potential future movements.<\/td><td>Backward-looking: It measures past movement.&nbsp;<\/td><\/tr><tr><td>Source of Data&nbsp;<\/td><td>Derived from current Option Prices.&nbsp;<\/td><td>Derived from Historical Stock Prices.&nbsp;<\/td><\/tr><tr><td>Nature&nbsp;<\/td><td>Subjective;

However, many market participants view options as instruments influenced by volatility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"line-height:1.8;text-align:justify\">The battle of <strong>implied volatility vs realised volatility<\/strong> is at the heart of the options market.

For instance, an IV of 20% signals a market consensus that the underlying asset could fluctuate within a 20% range \u2014 either upward or downward \u2014 by year-end. By applying the principles of standard deviation, traders can mathematically &#8220;de-annualize&#8221; this figure to estimate expected price swings for shorter timeframes, such as a single day or a week.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\" style=\"background:#f1f1f1;border-radius:4px;margin-bottom:10px\">\n<summary style=\"font-weight:600;font-size:17px;color:#1a2332;cursor:pointer;padding:16px 20px\">What is the difference between IV and HV?<\/summary>\n\n<p class=\"wp-block-paragraph\" style=\"padding:0 20px 18px 20px;line-height:1.8;color:#333;margin:0\">When an asset has experienced erratic price action lately, it is reflected in a spiked Historical Volatility (HV) reading. Conversely, a high Implied Volatility (IV) indicates that the market is currently bracing for a major shock, fueled by anxiety or the expectation of a high-impact catalyst. While RV helps you quantify the risk that has already materialized, IV allows you to gauge how much &#8220;fear&#8221; is currently being priced into option premiums.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\" style=\"background:#f1f1f1;border-radius:4px;margin-bottom:10px\">\n<summary style=\"font-weight:600;font-size:17px;color:#1a2332;cursor:pointer;padding:16px 20px\">Is higher implied volatility better?<\/summary>\n\n<p class=\"wp-block-paragraph\" style=\"padding:0 20px 18px 20px;line-height:1.8;color:#333;margin:0\">Elevated Implied Volatility (IV) acts as a catalyst for an enhanced, higher option premium. Because the market perceives greater future risk, buyers are willing to pay a &#8220;fear tax,&#8221; which allows option writers to receive relatively higher option premiums.<\/p>\n\n\n<p class=\"wp-block-paragraph\" style=\"padding:0 20px 18px 20px;line-height:1.8;color:#333;margin:0\">Conversely, a depressed IV environment leads to lower option premiums. As market uncertainty fades, the demand for protection drops, causing option prices to shrivel and reducing the available yield for income-focused strategies.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\" style=\"background:#f1f1f1;border-radius:4px;margin-bottom:10px\">\n<summary style=\"font-weight:600;font-size:17px;color:#1a2332;cursor:pointer;padding:16px 20px\">How do I calculate implied volatility?<\/summary>\n\n<p class=\"wp-block-paragraph\" style=\"padding:0 20px 18px 20px;line-height:1.8;color:#333;margin:0\">To determine implied volatility, one must reverse-engineer the Black-Scholes model by inputting the current market premium to isolate the specific volatility variable. While this &#8220;back-solving&#8221; method is standard, the financial world utilizes several distinct methodologies and algorithms to derive these forward-looking estimates.<\/p>\n\n<\/details>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:13px;line-height:1.6;color:#777\"><strong>DISCLAIMER:<\/strong> <strong>Investment in securities market are subject to market risks, read all the related documents carefully before investing.
