AT:MPC / Marathon Petroleum Corporation - Net Long/Short Value

This page provides the net long/short valuations for each institutional holding reported via 13F or NPORT filings. To calculate the net long/short value, we add the equity value to the call option value and subtract the put option value. Funds that report short-borrowed positions will report equity values as negatives. Net long positions will have positive numbers in the net long/short column, and net short positions will have negative values in that column.
