Market manipulation From Wikipedia, the free encyclopedia

describes a deliberate attempt to interfere with the free and fair operation of the market and create artificial, false or misleading appearances with respect to the price of, or market for, a security, commodity or currency.[1] Market manipulation is prohibited under Section 9(a)(2)[2] of the Securities Exchange Act of 1934, and in Australia under Section s 1041A of the Corporations Act 2001. The Act defines market manipulation as transactions which create an artificial price or maintain an artificial price for a tradable security.

Markets manipulation can occur in multiple ways:

Pools
"Agreements, often written, among a group of traders to delegate authority to a single manager to trade in a specific stock for a specific period of time and then to share in the resulting profits or losses."[3]
Churning
"When a trader places both buy and sell orders at about the same price. The increase in activity is intended to attract additional investors, and increase the price."
Runs
"When a group of traders create activity or rumors in order to drive the price of a security up." An example is the Guinness share-trading fraud of the 1980s. In the US, this activity is usually referred to as painting the tape[4].
Ramping (the market)
"Actions designed to artificially raise the market price of listed securities and to give the impression of voluminous trading, in order to make a quick profit."[5]
Wash sale
"Selling and repurchasing the same or substantially the same security for the purpose of generating activity and increasing the price"
Bear raid
"Attempting to push the price of a stock down by heavy selling or short selling."[6

The foreign exchange market is unique because of

  • its trading volumes,
  • the extreme liquidity of the market,
  • the large number of, and variety of, traders in the market,
  • its geographical dispersion,
  • its long trading hours: 24 hours a day (except on weekends),
  • the variety of factors that affect exchange rates.
  • the low margins of profit compared with other markets of fixed income (but profits can be high due to very large trading volumes)
Foreign exchange market turnover, 1988 - 2007, measured in billions of USD.
Foreign exchange market turnover, 1988 - 2007, measured in billions of USD.

As such, it has been referred to as the market closest to the ideal perfect competition, notwithstanding authorized market manipulation by central banks. According to the BIS,[1] average daily turnover in traditional foreign exchange markets is estimated at $3.21 trillion. Daily averages in April for different years, in billions of US dollars, are presented on the chart below:

This $3.21 trillion in global foreign exchange market "traditional" turnover was broken down as follows:

In addition to "traditional" turnover, $2.1 trillion was traded in derivatives.

Exchange-traded forex futures contracts were introduced in 1972 at the Chicago Mercantile Exchange and are actively traded relative to most other futures contracts. Forex futures volume has grown rapidly in recent years, and accounts for about 7% of the total foreign exchange market volume, according to The Wall Street Journal Europe (5/5/06, p. 20).

Average daily global turnover in traditional foreign exchange market transactions totaled $2.7 trillion in April 2006 according to IFSL estimates based on semi-annual London, New York, Tokyo and Singapore Foreign Exchange Committee data. Overall turnover, including non-traditional foreign exchange derivatives and products traded on exchanges, averaged around $2.9 trillion a day. This was more than ten times the size of the combined daily turnover on all the world’s equity markets. Foreign exchange trading increased by 38% between April 2005 and April 2006 and has more than doubled since 2001. This is largely due to the growing importance of foreign exchange as an asset class and an increase in fund management assets, particularly of hedge funds and pension funds. The diverse selection of execution venues such as internet trading platforms has also made it easier for retail traders to trade in the foreign exchange market. [2]

Because foreign exchange is an OTC market where brokers/dealers negotiate directly with one another, there is no central exchange or clearing house. The biggest geographic trading centre is the UK, primarily London, which according to IFSL estimates has increased its share of global turnover in traditional transactions from 31.3% in April 2004 to 32.4% in April 2006.

The ten most active traders account for almost 73% of trading volume, according to The Wall Street Journal Europe, (2/9/06 p. 20). These large international banks continually provide the market with both bid (buy) and ask (sell) prices. The bid/ask spread is the difference between the price at which a bank or market maker will sell ("ask", or "offer") and the price at which a market-maker will buy ("bid") from a wholesale customer. This spread is minimal for actively traded pairs of currencies, usually 0–3 pips. For example, the bid/ask quote of EUR/USD might be 1.2200/1.2203 on a retail broker. Minimum trading size for most deals is usually 100,000 units of currency, which is a standard "lot".

These spreads might not apply to retail customers at banks, which will routinely mark up the difference to say 1.2100 / 1.2300 for transfers, or say 1.2000 / 1.2400 for banknotes or travelers' checks. Spot prices at market makers vary, but on EUR/USD are usually no more than 3 pips wide (i.e. 0.0003). Competition is greatly increased with larger transactions, and pip spreads shrink on the major pairs to as little as 1 to 2 pips.
