• ストックCommon
  nounThe loanword for stock as a supply kept on hand. In business contexts it largely overlaps with 在庫, and either word works for goods held in stock.

• 血筋ちすじCommon

  血筋ちすじは争あらそえない。↗

  Blood is thicker than water.

For shares in a company use 株 (or the more formal 株式); for goods held in inventory use 在庫 or the loanword 「ストック」; 血筋 means stock only as family lineage or breeding.
