Telecoms crash

Companies such as WorldCom, Global Crossing, and Lucent Technologies had achieved enormous market valuations based on expectations of continued growth and profitability.

Many companies had taken on substantial debt to finance their expansion, and investors had poured billions of dollars into the sector based on unrealistic expectations of growth and profitability.
