Flash Crash Definition
A flash crash is a sudden and steep decline in the price of a financial asset or market, occurring within a very short time frame, often minutes or seconds, followed by a quick recovery. These events are typically triggered by automated trading systems and high-frequency trading, resulting in extreme market volatility.
What Is A Flash Crash?
A flash crash is an event characterized by a rapid, deep, and volatile drop in the price of one or more assets, occurring within a very short period, often seconds or minutes.
This phenomenon is usually followed by a swift rebound in prices, but not always to the pre-crash levels.
Who Is Involved In A Flash Crash?
Flash crashes primarily involve institutional traders, high-frequency trading firms, and automated trading algorithms.
Retail investors can also be significantly impacted, experiencing large losses or gains depending on their market positions.
Regulators and market analysts often step in post-event to assess causes and implications.
When Do Flash Crashes Occur?
Flash crashes can occur at any time but are often seen during periods of low liquidity or high market stress.
They can also be triggered by unexpected news events, erroneous trades, or malfunctions in trading algorithms.
Where Do Flash Crashes Happen?
Flash crashes can happen in any financial market, including stock markets, cryptocurrency exchanges, and foreign exchange markets.
They are more common in markets with high trading volumes and significant use of automated trading systems.
Why Do Flash Crashes Happen?
Flash crashes occur due to a combination of high-frequency trading, automated algorithms, and market panic.
Erroneous trades, software glitches, and lack of liquidity can exacerbate the speed and depth of the crash.
Investor behavior, such as panic selling, can also contribute to the rapid decline.
How Do Flash Crashes Occur?
Flash crashes typically begin with an initial trigger, such as a large sell order or a trading algorithm malfunction.
This initial event sets off a chain reaction of automated selling, amplifying the asset’s price decline in a matter of seconds.
Market safeguards and circuit breakers are sometimes activated to halt trading temporarily and restore order.
Prices often recover quickly once the initial panic subsides and normal trading resumes.
