The document discusses strategies for companies facing declining or hostile markets. In declining markets, lower sales lead to excess capacity and high inventory levels. There are four main strategies for declining markets: harvesting, maintenance, profitable survivor, and niche. Hostile markets have overcapacity, low margins, intense competition, and disorganized management. To succeed in hostile markets, companies can focus on reliability, large customers, cost management, expansion, covering multiple price points, and effective distribution. Both offensive and defensive strategies may be used, with defensive strategies aiming to safeguard position and offensive strategies seeking to create new growth opportunities.
