Why Arbitrage Is important? And How Many Types of It?

Arbitragers

The arbitrage trade is usually carried in stocks, currencies, and commodities. That’s an example of making profits without presuming the risk of a trade.

 Arbitrage requirements

Following are the requirements for carrying out the arbitrage,

  1. Perfect information is required to carry out successful arbitrage activity.
  2. The sale and purchase of the securities need to be made instantly.
  3. The transaction cost should be lower for the purchase of an asset or at least lower than the profit made by the arbitrage activity.
  4. The transaction cost should be lower for the purchase of the exchange of the currency.

Equilibrium and purchasing power parity theory

If the markets are in equilibrium there is no difference in the prices of the security, this means the markets do not provide the opportunity to make profits and is said to be in equilibrium. So, arbitrage can only be exercised in times the market faces inefficiency.

Similarly, the purchasing power parity theory states that the prices of the products in one country are probably equivalent to the price of the commodity in another country.

If the markets are under equilibrium as the price of the commodities are similar in line with purchasing power parity there is no opportunity for arbitrage.

  1. The sale and purchase transactions might not be at the same time and there may be some gap in the time. The prices might fluctuate in the gap and leading to loss rather than profit.
  2. The transaction price might be higher than the profits earned from the process of arbitrage leading to loss on the transaction.

Location-based arbitrage

Locational arbitrage is when an investor makes use of the minor difference in the exchange rate of two financial institutions. It’s based on the idea of buying from one bank and selling to other banks in a way that creates profitability for the investors.

However, these types of arbitrage are rare in the real world and very difficult to find.
