Great Opportunities to buy companies with durable competitive advantage

a) Correction or panic during a bull market:

Any company with a durable competitive advantage will eventually recover after a market correction or panic during a bull market.

b) Bubble-bursting situation:

But beware. In a bubble-bursting situation,during which stock prices trade in excess of 40 times earnings and then fall to single-digit PEs, it may take years for them to fully recover.

After the crash of 1997, it took until 2007 to match the 1990s bull market highs. There are still companies trading today at below their last decade high price. On the other hand, if you bought during the crash, as Warren Buffett often did, it didn't take you long to make a fortune.
