JSML aims to pick outperformers from the small-cap universe by selecting stocks with strong growth fundamentals (measured by ROIC, revenue growth, profit margin expansion, operating profit growth, and EPS growth). Smart beta funds already blur the line between passive and active management, but JSML goes a step further by relying on an active manager to determine its sector weighting, the portfolio is weighted to align by sector with the Janus Venture Fund, an actively-managed traditional mutual fund with a small-cap growth mandate. Individual holdings are market cap-weighted within sectors, and the portfolio is rebalanced quarterly. Sibling JSMD employs the same methodology but includes both small- and midcap stocks.
