Technical and Quantitative Research

Vermilion Research

Vermilion’s objective is to deliver timely, actionable, and unique technical research to professional investors through the application of our various technical indicators.

Our research strategists seek to highlight securities which we believe are at major inflection points, based on our various technical and quantitative indicators, and offer asymmetric risk/return profiles. Our unique research methodology, centered on relative strength, enables our strategists to deliver superior investment recommendations.

Our process begins by organizing the universe of actively traded stocks into discrete sectors, then into industry groups. We then apply our technical and quantitative tools to identify developing price trends. Once attractive trends are identified within a selected sector or group, we screen for individual stocks which we believe offer the best risk/reward profile. We provide a historical perspective that often reveals, through our long-term charts, how price patterns often repeat themselves over time.

Technical Analysis

<ul>
<li>We remain bullish since our 4/22/25 Compass, and we will maintain our bullish outlook as long as market dynamics remain healthy and the S&amp;P 500 (SPX) is above 6028-6059.</li>
<li>For now, we continue to expect support to show up at the 4-month uptrend, which generally coincides with the 20-day MA.</li>
<li>Speculative growth themes and metals/mining (GDX, XME) remain leadership, which we expect to continue through year-end and into the early part of 2026</li>
