A market swoon is generally characterized by a substantial interruption in trading combined with a high trading volume. An example of a market swoon would be a steep decline in the value of the S&P 500 Index.

Market swoons frequently occur in response to economic or political shocks (for example, interest rate increases and international conflicts). The market often recovers from a market swoon in a relatively short span of time.
