Speculation

In finance, speculation is the purchase of an asset (a commodity, goods, or real estate) with the hope that that asset will become more valuable in a brief amount of time. The term can also refer to short sales, in which the speculator hopes for a decline in value.

Many speculators pay little attention to the fundamental value of a security and instead focus purely on price movements.^{[citation needed]} In principle, speculation can involve any tradable good or financial instrument. Speculators are particularly common in the markets for stocks, bonds, commodity futures, currencies, cryptocurrency, fine art, collectibles, real estate, and financial derivatives.

Speculators play one of the four primary roles in financial markets, along with:

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

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. 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". The agency emphasizes that speculators serve important market functions, but defines excessive speculation as harmful to the proper functioning of futures markets.

According to Benjamin Graham in The Intelligent Investor, the prototypical defensive investor is "one interested chiefly in safety plus freedom from bother". He adds 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.

Nicholas Kaldor has long argued for the price-stabilizing role of speculators, who tend to even out "price-fluctuations due to changes in the conditions of demand or supply", by possessing "better than average foresight". This view was later echoed by the speculator Victor Niederhoffer, in "The Speculator as Hero", who 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.
