Forcing trades to quickly recover losses
📚 Case Studies
1
Pre-GFC Credit Caution (2005)
Structured credit and subprime-backed products were heavily promoted. Marks reduced risk, tightened covenants, and kept selectivity while others chased yield.
✨ Outcome：During the 2007–2009 crisis, Oaktree’s losses were limited and it had capital to buy distressed debt at attractive prices, outperforming peers.
2
Dot-Com Bust (2000)
Many tech stocks crashed as the bubble burst. Marks’ contrarian stance favored avoiding overpriced, profitless companies despite market euphoria.
✨ Outcome：By holding cash and quality value stocks, Oaktree preserved capital and later bought distressed assets at attractive prices.
