We take “linked” assets and trade them at the same time in opposite directions by BUYING the strong asset and SELLING the weak asset. This is an organic hedge against the market because if the entire sector is driven up, we have a bullish position on a strong stock in that sector that should outweigh our short position. If the entire sector is driven down, we are short a weak stock in that sector that should outweigh our long position. And if the sector is “quiet” there is a good chance the strong stock will keep grinding up and the weak stock will keep grinding down for a win on both sides.
