Speculation is the practice of engaging in risky financial transactions in an attempt to profit from fluctuations in the market value of a tradable good such as a financial instrument, rather than attempting to profit from the underlying financial attributes embodied in the instrument such as capital gains, interest, or dividends. Many speculators pay little attention to the fundamental value of a security and instead focus purely on price movements. Speculation can in principle involve any tradable good or financial instrument. Speculators are particularly common in the markets for stocks, bonds, commodity futures, currencies, fine art, collectibles, real estate, and derivatives.

Speculators play one of four primary roles in financial markets, along with hedgers who engage in transactions to offset some other pre existing risk, arbitrageurs who seek to profit from situations where fungible instruments trade at different prices in different market segments, and investors who seek profit through long-term ownership of an instrument's underlying attributes.

With the appearance of the stock ticker machine in 1867, which abrogated the need for traders to be physically present on the floor of a stock exchange, stock speculation underwent a dramatic expansion through to the end of the 1920s, the number of shareholders increasing, perhaps, from 4.4 million in 1900 to 26 million in 1932.[1]

Speculation and investment

The view of what distinguishes investment from speculation and speculation from excessive speculation varies widely among pundits, legislators and academics. Some sources note that speculation is simply a higher risk form of investment. Others define speculation more narrowly as positions not characterized as hedging.[2] The U.S. Commodity Futures Trading Commission defines a speculator as "a trader who does not hedge, but who trades with the objective of achieving profits through the successful anticipation of price movements."[3] The agency emphasizes that speculators serve important market functions, but defines excessive speculation as harmful to the proper functioning of futures markets.[4]

According to Ben Graham in The Intelligent Investor, the prototypical defensive investor is " interested chiefly in safety plus freedom from bother." He admits, however, that "...some speculation is necessary and unavoidable, for in many common-stock situations, there are substantial possibilities of both profit and loss, and the risks therein must be assumed by someone." Thus, many long-term investors, even those who buy and hold for decades, may be classified as speculators, excepting only the rare few who are primarily motivated by income or safety of principal and not eventually selling at a profit.[5]

The economic benefits of speculation

Sustainable consumption level

Speculation usually involves more risks than investment.

The speculator Victor Niederhoffer, in "The Speculator as Hero"[6] describes the benefits of speculation:

Let's consider some of the principles that explain the causes of shortages and surpluses and the role of speculators. When a harvest is too small to satisfy consumption at its normal rate, speculators come in, hoping to profit from the scarcity by buying. Their purchases raise the price, thereby checking consumption so that the smaller supply will last longer. Producers encouraged by the high price further lessen the shortage by growing or importing to reduce the shortage. On the other side, when the price is higher than the speculators think the facts warrant, they sell. This reduces prices, encouraging consumption and exports and helping to reduce the surplus.

Another service provided by speculators to a market is that by risking their own capital in the hope of profit, they add liquidity to the market and make it easier or even possible for others to offset risk, including those who may be classified as hedgers and arbitrageurs.

Market liquidity and efficiency

If any particular market—for example, pork bellies—had no speculators, then only producers (the hog farmers) and consumers (butchers, etc.) would participate in that market. With fewer players in the market, there would be a larger spread between the current bid and ask price of pork bellies. Any new entrant in the market who wanted to trade pork bellies would be forced to accept an illiquid market, may trade at market prices with large bid-ask spreads, or even face difficulty finding a co-party to buy or sell to.

A commodity speculator may profit the difference in the spread and, in competition with other speculators, reduce the spread. Some schools of thought argue that speculators increase the liquidity in a market, and therefore promote an efficient market.[7] As more and more speculators participate in a market, underlying real demand and supply can become diminishingly small compared to trading volume, and prices may become distorted. [8] Without speculators, it is difficult to create an efficient market. Speculators are there to take information, and speculate on how it effects prices, producers and consumers, who may want to hedge their risks, need counter-parties, if they could find each other without markets it certainly would happen as it would be cheaper. The benefit of price discovery provided as a byproduct by speculators is of great benefit to the economy as a whole as well.

Bearing risks

Speculators also perform a very important risk bearing role that is beneficial to society. For example, a farmer might be considering planting corn on some unused farmland. Alas, he might not want to do so because he is concerned that the price might fall too far by harvest time. By selling his crop in advance at a fixed price to a speculator, the farmer can hedge the price risk and is now willing to plant the corn. Thus, speculators can actually increase production through their willingness to take on risk.

Finding environmental and other risks

Hedge funds that do fundamental analysis "are far more likely than other investors to try to identify a firm’s off-balance-sheet exposures", including "environmental or social liabilities present in a market or company but not explicitly accounted for in traditional numeric valuation or mainstream investor analysis", and hence make the prices better reflect the true quality of operation of the firms.[9]


Shorting may act as a "canary in a coal mine" to stop unsustainable practices earlier and thus reduce damages and forming market bubbles.[9]

The economic disadvantages of speculation

Winner's Curse

Auctions are a method of squeezing out speculators from a transaction, but they may have their own perverse effects; see winner's curse. The winner's curse is however not very significant to markets with high liquidity for both buyers and sellers, as the auction for selling the product and the auction for buying the product occur simultaneously, and the two prices are separated only by a relatively small spread. This mechanism prevents the winner's curse phenomenon from causing mispricing to any degree greater than the spread.

Economic Bubbles

Speculation is often associated with economic bubbles. A bubble occurs when the price for an asset exceeds its intrinsic value by a significant margin.,[10] although not all bubbles occur because of speculation.[11] Speculative bubbles are characterized by rapid market expansion driven by word-of-mouth feedback loops as initial rises in asset price attract new buyers and generate further inflation.[12] The creation of the bubble is followed by a precipitous collapse fueled by the same phenomenon.[10][13] Speculative bubbles are essentially social epidemics whose contagion is mediated by the structure of the market.[13] Some economists link asset price movements within a bubble to fundamental economic factors such as cash flows and discount rates.[14]

In 1936 John Maynard Keynes wrote: "Speculators may do no harm as bubbles on a steady stream of enterprise. But the situation is serious when enterprise becomes the bubble on a whirlpool of speculation. (1936:159)"[15] Mr Keynes himself enjoyed speculation to the fullest, running an early precursor of a hedge fund. As the Bursar of the Cambridge University King's College, he managed two investment funds, one of which, called Chest Fund, invested not only in the then 'emerging' market US stocks, but also periodically included commodity futures and foreign currencies, albeit to a smaller extent (see Chua and Woodward, 1983) . His fund achieved positive returns in almost every year, averaging 13% p.a., even during the Great Depression, thanks to very modern investment strategies, which included inter-market diversification (i.e., invested not only in stocks but also commodities and currencies) as well as shorting, i.e., selling borrowed stocks or futures to make money on falling prices, which Keynes advocated among the principles of successful investment in his 1933 report ("a balanced investment position [...] and if possible, opposed risks.") [16]


According to Ziemba and Ziemba (2007), Keynes risk-taking reached 'cowboy' proportions, i.e. 80% of the maximum rationally justifiable levels (of the so-called Kelly criterion), with overall return volatility approximately three times higher than the stock market index benchmark. Such levels of volatility, responsible for his spectacular investment performance, would be achievable today only through the most aggressive instruments (such as 3:1 leveraged exchange-traded funds). He chose modern speculation techniques practiced today by hedge funds, which are quite different from the simple buy-and-hold long-term investing.[17]

It is a controversial point whether the presence of speculators increases or decreases the short-term volatility in a market. Their provision of capital and information may help stabilize prices closer to their true values. On the other hand, crowd behavior and positive feedback loops in market participants may also increase volatility at times.

Government responses and regulation

The economic disadvantages of speculators has resulted in a number of attempts over the years to introduce regulations and restrictions to try and limit or reduce the impact of speculators. Such financial regulation is often enacted in response to a crisis as was the case with the Bubble Act 1720 which was passed by the British government at the height of the South Sea Bubble to try stop speculation in such schemes. This act was left in place for over a hundred years and was repealed in 1825. Another example was the Glass–Steagall legislation passed in 1933 during the Great Depression in the United States, most of the Glass-Steagall provisions were repealed during the 1980s and 1990s. The Onion Futures Act bans the trading of futures contracts on onions in the United States, after speculators successfully cornered the market in the mid-1950s; it remains in effect as of 2013.

Food security

Some nations have moved to limit foreign ownership of cropland in order to ensure that food is available for local consumption while others have sold food land and depend on the World Food Programme.[18]

In 1935 the Indian government passed a law allowing the government to in part restrict and directly control food production (Defence of India Act, 1935). This included the ability to restrict or ban the trading in derivatives on those food commodities. Post independence, in the 1950s, India continued to struggle with feeding its population and the government increasingly restricting trading in food commodities. Just at the time the Forward Markets Commission was established, the government felt that derivative markets increased speculation which led to increased costs and price instabilities. And in 1953 finally prohibited options and futures trading altogether.[19] These restrictions were not lifted until the 1980s.


In the US following passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the U.S., Commodity Futures Trading Commission (CFTC) has proposed regulations aimed at limiting speculation in futures markets by instituting position limits. The CFTC offers three basic elements for their regulatory framework: "the size (or levels) of the limits themselves; the exemptions from the limits (for example, hedged positions) and; the policy on aggregating accounts for purposes of applying the limits."[20] The proposed position limits apply to 28 physical commodities traded in various exchanges across the U.S.[21]

Another part of the Dodd-Frank Act established the Volcker Rule which deals with speculative investments of banks that don't benefit their customers. The Volcker Rule passed on 21 January 2010 states that these investments played a key role in the financial crisis of 2007–2010.[22]


A number of proposals have been made in the past to try and limit speculation that were never enacted, these have included:

  • The Tobin tax is a tax intended to reduce short-term currency speculation, ostensibly to stabilize foreign exchange.
  • In May 2008 German leaders planned to propose a worldwide ban on oil trading by speculators, blaming the 2008 oil price rises on manipulation by hedge funds.[23]
