The new charts show how spreads have evolved over time and capture not just the average, but also the range\u2014from the tightest to the widest spreads observed. This offers investors a realistic sense of what they might pay to trade under both normal and volatile market conditions.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote alignright has-text-align-right has-vivid-cyan-blue-color has-text-color has-link-color has-medium-font-size wp-elements-a86d6b1a0787abf16d486e96924fa936\"><blockquote><p>Wide spreads can <br>quickly offset years <br>of savings on fees<\/p><\/blockquote><\/figure>\n\n\n\n<p>Our ETF spread data is calculated using the National Best Bid and Offer (NBBO) observed at various times throughout the trading day, providing a detailed and representative measure of real-world trading costs. To our knowledge, this type of data is not readily available to most investors without access to costly institutional platforms like Bloomberg. Although some sites may display a current or delayed quote of the bid\/ask spread, that single snapshot tells only part of the story\u2014our data reflects the trading experience over time.<\/p>\n\n\n\n<p>This enhancement also powers our <strong>Total Cost of Ownership (TCO)<\/strong> analysis, which combines expense ratios with average trading spreads to estimate the true cost of holding an ETF. Many investors focus primarily on expense ratios, but since differences between funds often amount to just a few basis points, even a slightly wider spread can quickly offset years of savings on fees. Our TCO tool helps investors make better, more comprehensive cost comparisons.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"526\" src=\"https:\/\/www.etfrc.com\/articles\/wp-content\/uploads\/2025\/11\/spreads_tab-1024x526.png\" alt=\"\" class=\"wp-image-2410\" srcset=\"https:\/\/www.etfrc.com\/articles\/wp-content\/uploads\/2025\/11\/spreads_tab-1024x526.png 1024w, https:\/\/www.etfrc.com\/articles\/wp-content\/uploads\/2025\/11\/spreads_tab-300x154.png 300w, https:\/\/www.etfrc.com\/articles\/wp-content\/uploads\/2025\/11\/spreads_tab-768x394.png 768w, https:\/\/www.etfrc.com\/articles\/wp-content\/uploads\/2025\/11\/spreads_tab.png 1512w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>You can explore this data on any ETF\u2019s focus page under the <strong>\u201cTrading &amp; Costs\u201d<\/strong> tab, such as shown here: <a href=\"https:\/\/www.etfrc.com\/BLOK\" target=\"_blank\" rel=\"noreferrer noopener\">BLOK<\/a>.
