Why does flash crash so much

In Bitcoin markets there are no trading halts to stabilize the market, so investors must manage this risk through their own trading strategies. The exact strategy an investor uses depends on their risk tolerance and how they expect the market to react to the crash. In many cases, a flash crash is completely temporary, and the price rebounds as quickly as it dropped.

This is especially likely if the crash was due to a single actor placing a large sell. To prepare for this scenario an investor may use limit orders to buy more of the asset when the price declines, selling once it goes back up. In other scenarios, the flash crash may be followed by continued drops in price.

This is likely if the crash was triggered by news that materially affects the value of the asset. In order to limit potential downside, an investor may implement a stop-loss or stop-limit strategy to automatically exit a position if the price drops below a specified threshold.

However, the risk of this strategy is that an investor exits a position for a loss and then misses the upside of the price recovery. A much simpler approach is to simply maintain consistent exposure to an asset, regardless of changes in the price. Markets are typically very difficult to predict, and trying to time them may lead to lower returns. By minimizing active trading, an investor eliminates the complications of trying to time the market.

Additionally, minimizing active trading avoids trading fees associated with constantly changing an investment position. Why Is Bitcoin Volatile? Bitcoin has historically been a volatile asset. This volatility is primarily due to the nascency of the currency, and is expected to decline as the market matures. How Is the Bitcoin Price Determined? The Bitcoin price is determined through supply and demand. Because the market cap of bitcoin is small relative to the market capitalization of other currencies, small changes in demand or supply can produce price volatility greater than that of fiat currencies with theoretically unlimited supply.

What Is a Bear Market? A bear market is characterized by declining asset prices and negative investor sentiment. Bitcoin markets may experience a bear market at different times than equity markets. Login Sign Up.

A flash crash is an event in electronic securities markets wherein the withdrawal of stock orders rapidly amplifies price declines, and then quickly recovers. The result appears to be a rapid sell-off of securities that can happen over a few minutes, resulting in dramatic declines.

However, usually by the end of the trading day, as prices have rebounded, it's as if the flash crash never happened. A flash crash, like the one that occurred on May 6, , is exacerbated as computer trading programs react to aberrations in the market, such as heavy selling in one or many securities, and automatically begin selling large volumes at an incredibly rapid pace to avoid losses.

Flash crashes can trigger circuit breakers at major stock exchanges like the New York Stock Exchange NYSE , which halt trading until buy and sell orders can be matched up evenly and trading can resume in an orderly fashion.

Especially as trading has become more digitized, flash crashes are usually triggered by these computer algorithms rather than a specific piece of market or company news that causes the quick selloff. As the price continues to drop and more benchmarks are triggered, it can cause a domino effect that sets off a sudden plunge in value.

That being said, a lot more research is needed on flash crashes, including any indication of fraudulent activity. As securities trading has become a more heavily computerized industry that is driven by complicated algorithms across global networks, the propensity for glitches, errors, and even flash crashes has risen. That said, global exchanges like the NYSE, Nasdaq, and the CME have put in place stronger security measures and mechanisms to prevent them and the staggering losses they can lead to.

For example, they have put in place market-wide circuit breakers that trigger a pause or a complete stop in trading activity.

The SEC also banned naked access or direct connections to exchanges. High-frequency trading firms, who have been blamed for precipitating the flash crash's effects, often use their broker-dealer's code in order to access exchanges directly.

Such measures cannot eliminate flash crashes altogether, but they have been able to mitigate the damages they can cause. Shortly after p. EST on May 6, , a flash crash began as the Dow Jones Industrial Average fell more than 1, points in 10 minutes, the biggest drop in history at that point.

That's why so many asset classes move in tandem. These programs aren't regulated, either. But the situation isn't hopeless. It's impossible to outthink these programs on a day-to-day basis, but you can tell where the market is headed by following the business cycle. Keep a well-diversified portfolio. Adjust your asset allocation each quarter to make a decent return. Remember, it's not how much you make, but how little you lose.
