ProShares Large Cap Core Plus 

This fund, managed by ProShare Advisors, seeks to closely mirror the performance of a particular benchmark index by investing in a range of financial instruments. The underlying index employs a sophisticated investment strategy that involves taking both bullish (long) and bearish (short) positions in the shares of 500 prominent large-capitalization U.S. companies, collectively known as the "Universe." The allocation and weighting of these companies within the index are governed by a systematic, predefined set of rules. It should also be noted that the fund maintains a concentrated portfolio, rather than being broadly diversified.
