The High-Frequency Trading Domination in the US
High-Frequency trading systems open and close positions in a fraction of a second and form the million-second markets. These Fast-Markets are extremely liquid and can highly influence all real Equity Markets. It is estimated that 50% of the total US stock-trading volume is driven by computer-based high frequency trading systems. Others believe that today the activity of HFT exceeds 65% of the total US stocks activity. High Frequency Trading has become very popular nowadays. There are hundreds of new start-up companies worldwide focusing exclusively on exploiting opportunities deriving from this lucrative market. Only in the US the High Frequency Trading industry is estimated to worth about 300 billion USD. In overall, there are more than 20,000 firms in the US that are specialized in high-past computerized programs for trading stocks. The most important players in the HFT industry according to the Deutsche Bank are:
i) Multi-Service Firms: Citigroup and Goldman Sachs
ii) Hedge-Funds: Citadel and Renaissance Technologies
iii) Trading Firms: Getco, Optiver and Tradebot
Why HFT makes Investors and Regulators Skeptical?
In May, 6th 2010 the Dow Jones Industrial plunged 600 points in just five minutes. This is the so-called "Flash Crash" of 2010. The DJIA after the 400-point drop was able to recover within 20 minutes and closed the day about 3.0% down. High Frequency Trading held responsible for this abnormal DJIA behavior and since then HFT made everyone skeptical about the future.
High-Frequency Trading Strategies
Here are the main high-frequency trading strategies:
1) Market Making Strategy
This is the simplest way to profit from high-frequency trading. Market making strategy involves placing 2 controversial trades (bid and ask) in order to profit from the bid-ask spread.
2) Low-Latency Arbitrage
This trading strategy relies on low latency technology. The ability of trading fast can lead to the exploitation of price inefficiencies when the same security is traded simultaneously on two disparate markets.
3) News-Trading Strategies
This is a very popular method of speculation. Macroeconomic or company news create a predictable row of fluctuations. HFT systems given the right configuration can process and trade the news faster than individual human traders.
4) Event Arbitrage
This strategy aims to exploit predictable short-term fluctuations after important events.
5) Statistical Arbitrage
The statistical arbitrage strategies are designed to take advantage of temporary deviations from important historic statistical relationships among certain financial assets.
High Frequency Trading Basic Glossary
1. What is High Frequency Trading (HFT)? Definition by Nasdaq
High Frequency Trading is computerized trading using proprietary algorithms. There are two types HFT trading:
(i) Execution trading is when an order (often a large order) is executed via a computerized algorithm. The program is designed to get the best possible price. It may split the order into smaller pieces and execute at different times.
(ii) The 2nd type of high frequency trading is not executing a set order but looking for small trading opportunities in the market.
2. What is Latency?
Latency is the time needed for a signal to be sent and to be received. The lower the latency the faster is the trading. The speed of light in a fiber optic cable is stable to 186,000 miles per second so Latency in a high extend is determined by Geography (distance between the location of the signal sender and the signal receiver).
3. What is Co-Location?
Co-Location means that the servers of the HFT firms are located in the same premises where the exchange’s servers are situated. Co-Location offers the opportunity to HFT firms to access prices a split second before anyone else. The location of the servers of a HFT firm is also called the ‘Point of Presence’.
4. What is Statistical Arbitrage?
