ROI, with an expense ratio of 0.38%, is designed to track the WisdomTree LargeCap Growth Index, a fundamentally weighted index that measures the stock performance of approximately 300 large-cap growth companies in the U.S., with initial weights of each company in the index set annually based on earnings generated in the prior four fiscal quarters, according to a news release.

“We believe growth’s historic underperformance may have more to do with how the major growth indexes are constructed, than with growth stocks themselves,” said Jonathan Steinberg, WisdomTree CEO, in the news release. “WisdomTree’s investment philosophy can be applied across the entire field of equity investing. Bringing our fundamental weighting methodology to the growth universe is an important extension of our effort to address what we believe to be the flaws of traditional, market capitalization-weighted indexes.”
