Arbitrageur
An arbitrageur is an investor who attempts to profit from market inefficiencies. Many arbitrageurs seek to profit from the same asset being priced differently in separate markets by simultaneously buying the asset at a lower price and selling it at a higher price. Alternatively, risk arbitrageurs try to profit from price differences during mergers and acquisitions before they close.

Definition
An arbitrageur is an investor who seeks to profit from market inefficiencies. Many arbitrageurs attempt to profit by simultaneously buying and selling the same asset in different markets at different prices. They buy the asset in the market where the price is lower and sell it in the market where the price is higher. On the other hand, risk arbitrageurs try to profit from price differences before a merger or acquisition is completed.
Origin
The concept of arbitrage dates back to the 19th century when financial markets began to globalize, and investors discovered price differences between different markets. With advancements in technology and communication, arbitrage trading has become more common and complex.
Categories and Characteristics
Arbitrage can be divided into several types, including:
- Spatial Arbitrage: Exploiting price differences between different markets.
- Temporal Arbitrage: Exploiting price differences at different times in the same market.
- Risk Arbitrage: Profiting from predicted price changes in merger and acquisition transactions.
Each type of arbitrage has its unique application scenarios and risks. For example, spatial arbitrage requires fast trade execution and low transaction costs, while risk arbitrage requires in-depth knowledge of merger and acquisition transactions.
Specific Cases
Case 1: Suppose a stock is listed on both the New York Stock Exchange (NYSE) and the London Stock Exchange (LSE). If the stock price is $100 on the NYSE and $102 on the LSE, an arbitrageur can buy the stock on the NYSE and sell it on the LSE, making a risk-free profit of $2.
Case 2: In a merger transaction, suppose Company A announces it will acquire Company B at $50 per share, and Company B's current stock price is $45. An arbitrageur can buy Company B's stock, expecting the price to rise to $50 after the transaction is completed, thus making a $5 profit.
Common Questions
Q: Is arbitrage trading completely risk-free?
A: While arbitrage trading is generally considered low-risk, it is not entirely risk-free. Market volatility, transaction costs, and execution risks can all impact the success of arbitrage trades.
Q: Can ordinary investors engage in arbitrage trading?
A: Although ordinary investors can attempt arbitrage trading, it typically requires fast trade execution and low transaction costs, which are usually only achievable by professional investors and institutions.
