Investment: Property or another possession acquired for future financial return or benefit.
Investment is putting money into something with the expectation of profit. More specifically, investment is the commitment of money or capital to the purchase of financial instruments or other assets so as to gain profitable returns in the form of interest, dividends, or appreciation of the value of the instrument
By any of these standards, speculation seems to be a not so distinct from investment.
Benjamin Graham
said, "The difference between investment and speculation is understood in a general way by nearly everyone, but when we try to formulate it precisely, we run into perplexing difficulties. In fact something can be said for the cynic's definition that an
investment is a successful speculation and a speculation an unsuccessful investment."
With very vague definitions it is easy for "speculation" to simply become moral condemnation for "investment practices ones doesn't agree with". In order to cut through the rhetoric, a thorough understanding of what speculation is and what function it serves is necessary. It seems that "speculators" are the go-to scapegoat for any and every economic bubble.
Any answer like that always strikes me as too easy and doesn't really to explain anything. How was speculation able to create a bubble in one market but not another? What other factors (if any) facilitated that bubble?
Philip L. Carret provided an interesting definition, "Pure speculation involves buying and selling in the same market without rendering any service in the way of distribution, storage and transportation".
Speculators
do provide a value. They often have a knowledge of the markets they are investing in (which is far different then a knowledge of the commodity itself, and in some ways more valuable). That knowledge mixed with the profit motive typically allows them to more efficiently distribute resources; meeting higher demand when it occurs, liquidating excessive supply, etc.
Murray Rothbard
said, "the more...[a] speculative, element enters into supply and demand, the more quickly will the market price tend toward equilibrium."
Speculators also assume risk (probably their primary function). While a farmer has a stronger understanding how to grow wheat then a speculator, that speculator typically has a stronger understanding of the wheat
market. This means when he agrees to buy the wheat from the farmer at harvest time at a price agreed to beforehand, the risk the farmer would otherwise assume in selling it himself is transferred to the speculator who, due to his knowledge of the market, reduces that risk. The sheer size of the speculators assets may also reduce the risk to them.
The point about speculation, on a large scale, being used to manipulate markets is worth looking into, but it can only get confusing without a strong understanding of what speculation is and is not.
However, on that, it seems we can agree that speculation seems to serve a positive purpose unless and until it gains undue
influence in the market (as opposed to simply reacting to and
anticipating the market).
As to the gambling analogy, one of my favorite economists, Thomas Sowell, made an interesting point on this in his book, Basic Economics;
Speculation is often misunderstood as being the same as gambling, when in fact it is the opposite of gambling. What gambling involves, whether in games of chance or in actions like playing Russian roulette, is creating a risk that would otherwise not exist, in order to either profit or to exhibit one's skill or lack of fear. What economic speculation involves is coping with an inherent risk in such a way as to minimize it and to leave it to be borne by whoever is best equipped to bear it.
Couldn't go without quoting Sowell.
