What are the 2 types of Stock Market crashes

Stock Market crashes are often sudden and dramatic with no warning. They can last for a short period of less than 1 month or can extend for years.

The S&P500 has demonstrated in over 100 years that US Stock Market crashes always recover eventually. The issue with Stock Market Crashes is:

(i)         How severe is the fall

(ii)        How long until recovery

1.1     Classification of Crashes

At Ultima Investment Services we classify crashes into one of three types:

(i)         News Event Crashes

-Falls of less than around -8%

-Recovery in less than 3 months

(ii)        Bear Crashes

-Falls of around -10%

-Recovery in less than 6 months

(iii)       Big Bear Crashes

-Falls of -20% or more

-Recovery in 12 months or more

For traders and Fund Managers a major issue is how long to rebound or recover after a fall.

News Events Crashes recover very quickly in less than 3 months as there is no fundamental reason for a sustained crash. Big Bear Crashes can last for over 12 months (some such as in 2000/1 can last for 36 months).

What are the features of each crash type and can any can be predicted ?

1.2     News Event Crashes

Primary Cause:

A major negative news event such as:

-War(s)

-Oil or other Energy supply restrictions (export tariffs, embargoes etc)

-Adverse political policies that have a negative impact on business profits

-Trade import tariffs and other import/export restrictions

With these types of events, there is usually a sudden huge drop in the S&P500. Trading entities such as the e mini ES futures and others always hold a large number of algo stop loss orders that are executable 23 hours a day and for almost 7 days a week. When stop loss levels are hit, orders are filled at almost any price which escalates the price fall into a flood.

A common feature of news event crashes is that investors review quickly whether the event will have a major impact on business profits or not. With News Event Crashes, forecast business Earnings reported just after the crash starts by S&P500 companies do not indicate a significant fall in Earnings.

These types of crashes do not usually result in a major Bear down period over an extended period.

The S&P500 prices rebound quite quickly usually within three months.

1.3     Bear and Big Bear Crashes

Primary Cause:

Business Earnings crash.

Business profits fall for most companies when:

-Interest rates rise more than 2 to 3% as consumer spending is decimated (especially discretionary spending).

-Major political policies that reduce business profits such as:

            -Escalation in employee wages

            -Additional employment costs

            -Additional compliance costs

            -Anti business development approval processes

            -New or increased taxes on consumers

With this type of crash, the S&P500 may fall initially a large amount, but more likely there will be a series of falls with false rebounds until business Earnings recover.

A major fall in Earnings over one Quarter is likely to lead to a Bear Crash. Huge falls in Earnings or accumulated falls over more than one Quarter is likely to result in a Big Bear Crash.

Companies issue EPS Estimates which are the best indication of business profits and how long the crash will last. Basically when Earnings recover, share prices will recover.

A Bear Crash continues for around 6mths. If it extends for more than 12mths it can be regarded as a Big Bear crash.
