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

iShares MSCI China ETF / Technical Analysis

<ul>
<li>We remain near-term bullish since our 4/22/25 Compass, and our intermediate-term outlook remains bullish as well (as of our 5/14/25 Compass).</li>
<li>Short-Term supports on the SPX include the 20-day MA (currently 6233), 6200, 6100-6150, and 6028-6059, with additional supports at 5804-5854 and 5700-5785. Buy pullbacks to these areas.</li>
<li>SPX has not closed below its 20-day MA for two months, but even when it does, all we would expect to happen is for a new, less-steep uptrend to form.</li>
