Tracking error is the volatility of the daily gaps. Both matter: you want low tracking difference (fund doesn&#8217;t consistently lag) AND low tracking error (consistent performance). A fund could have zero tracking error but consistently underperform by the expense ratio.<\/p>\n\n\n\n<h2 id='how-to-find-tracking-error-data'  id=\"boomdevs_4\" class=\"wp-block-heading\"><strong>How to Find Tracking Error Data<\/strong><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Check the fund&#8217;s factsheet; most AMCs publish monthly factsheets<\/li>\n\n\n\n<li>SEBI mandates disclosure of tracking error in scheme information documents<\/li>\n\n\n\n<li>Use AMFI&#8217;s website to download fund performance data for manual calculation<\/li>\n\n\n\n<li>Platforms like MFCentral and Value Research publish tracking error metrics<\/li>\n<\/ol>\n\n\n\n<h2 id='tracking-error-comparison-top-nifty-50-funds'  id=\"boomdevs_5\" class=\"wp-block-heading\"><strong>Tracking Error Comparison: Top Nifty 50 Funds<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th><strong>Fund<\/strong><\/th><th><strong>1Y Tracking Error<\/strong><\/th><th><strong>1Y Tracking Difference<\/strong><\/th><th><strong>TER<\/strong><\/th><\/tr><\/thead><tbody><tr><td>SBI ETF Nifty 50<\/td><td>~0.02%<\/td><td>~0.07%<\/td><td>0.07%<\/td><\/tr><tr><td>HDFC Nifty 50 Index Fund<\/td><td>~0.03%<\/td><td>~0.22%<\/td><td>0.20%<\/td><\/tr><tr><td>UTI Nifty 50 Index Fund<\/td><td>~0.04%<\/td><td>~0.24%<\/td><td>0.20%<\/td><\/tr><tr><td>Nippon India ETF BeES<\/td><td>~0.02%<\/td><td>~0.04%<\/td><td>0.04%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 id='practical-takeaways'  id=\"boomdevs_6\" class=\"wp-block-heading\"><strong>Practical Takeaways<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For ETFs: Prioritise tracking error &#8211; consistent replication is critical<\/li>\n\n\n\n<li>For index funds: Prioritise tracking difference &#8211; total return gap matters more<\/li>\n\n\n\n<li>Expense ratio is the primary driver &#8211; choose lowest TER in your preferred category<\/li>\n\n\n\n<li>Large AUM generally means better replication due to lower cash drag percentage<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>What is Tracking Error?
