A market trend is a tendency of a financial market to move in a particular direction over time. These trends are classified as secular for long time frames, primary for medium time frames, and secondary for short time frames. Traders identify market trends using technical analysis, a framework which characterizes market trends as predictable price tendencies within the market when price reaches support and resistance levels, varying over time.
A secular market trend is a long-term trend that lasts 5 to 25 years and consists of a series of primary trends. A secular bear market consists of smaller bull markets and larger bear markets; a secular bull market consists of larger bull markets and smaller bear markets.
In a secular bull market the prevailing trend is "bullish" or upward-moving. The United States stock market was described as being in a secular bull market from about 1983 to 2000 (or 2007), with brief upsets including the crash of 1987 and the market collapse of 2000-2002 triggered by the dot-com bubble.
In a secular bear market, the prevailing trend is "bearish," or downward-moving. An example of a secular bear market occurred in gold between January 1980 to June 1999, culminating with the Brown Bottom. During this period the nominal gold price fell from a high of $850/oz ($30/g) to a low of $253/oz ($9/g), and became part of the Great Commodities Depression.
A primary trend has broad support throughout the entire market (most sectors) and lasts for a year or more.
A bull market is associated with increasing investor confidence, and increased investing in anticipation of future price increases (capital gains). A bullish trend in the stock market often begins before the general economy shows clear signs of recovery. (capital)
A bear market is a general decline in the stock market over a period of time. It is a transition from high investor optimism to widespread investor fear and pessimism. According to The Vanguard Group, "While there’s no agreed-upon definition of a bear market, one generally accepted measure is a price decline of 20% or more over at least a two-month period."
A market top (or market high) is usually not a dramatic event. The market has simply reached the highest point that it will, for some time (usually a few years). It is retroactively defined as market participants are not aware of it as it happens. A decline then follows, usually gradually at first and later with more rapidity. William J. O'Neil and company report that since the 1950s a market top is characterized by three to five distribution days in a major market index occurring within a relatively short period of time. Distribution is a decline in price with higher volume than the preceding session.
A recent peak for the broad U.S. market was October 9, 2007. The S&P 500 index closed at 1,565 and the Nasdaq at 2861.50.
A market bottom is a trend reversal, the end of a market downturn, and precedes the beginning of an upward moving trend (bull market).
It is very difficult to identify a bottom (referred to by investors as "bottom picking") while it is occurring. The upturn following a decline is often short-lived and prices might resume their decline. This would bring a loss for the investor who purchased stock(s) during a misperceived or "false" market bottom.
Baron Rothschild is said to have advised that the best time to buy is when there is "blood in the streets", i.e., when the markets have fallen drastically and investor sentiment is extremely negative.
Secondary trends are short-term changes in price direction within a primary trend. The duration is a few weeks or a few months.
One type of secondary market trend is called a market correction. A correction is a short term price decline of 5% to 20% or so. A correction is a downward movement that is not large enough to be a bear market (ex post).
Another type of secondary trend is called a bear market rally (sometimes called "sucker's rally" or "dead cat bounce") which consist of a market price increase of only 10% or 20% and then the prevailing, bear market trend resumes. Bear market rallies occurred in the Dow Jones index after the 1929 stock market crash leading down to the market bottom in 1932, and throughout the late 1960s and early 1970s. The Japanese Nikkei 225 has been typified by a number of bear market rallies since the late 1980s while experiencing an overall long-term downward trend.
Investor sentiment is a contrarian stock market indicator.
By definition, the market balances buyers and sellers, so it's impossible to literally have 'more buyers than sellers' or vice versa, although that is a common expression. The market comprises investors and traders. The investors may own a stock for many years; traders put on a position for several weeks down to seconds.
Generally, the investors follow a buy low, sell high strategy. Traders attempt to "fade" the investors' actions (buy when they are selling, sell when they are buying). A surge in demand from investors lifts the traders' asks, while a surge in supply hits the traders' bids.
When a high proportion of investors express a bearish (negative) sentiment, some analysts consider it to be a strong signal that a market bottom may be near. The predictive capability of such a signal (see also market sentiment) is thought to be highest when investor sentiment reaches extreme values. Indicators that measure investor sentiment may include:
David Hirshleifer sees in the trend phenomenon a path starting with underreaction and ending in overreaction by investors / traders.
The precise origin of the phrases "bull market" and "bear market" are obscure. The Oxford English Dictionary cites an 1891 use of the term "bull market". In French "bulle spéculative" refers to a speculative market bubble. The Online Etymology Dictionary relates the word "bull" to "inflate, swell", and dates its stock market connotation to 1714.
The fighting styles of both animals may have a major impact on the names. When a bull fights it swipes its horns up; when a bear fights it swipes down on its opponents with its paws.
One hypothetical etymology points to London bearskin "jobbers" (market makers), who would sell bearskins before the bears had actually been caught in contradiction of the proverb ne vendez pas la peau de l'ours avant de l’avoir tué ("don't sell the bearskin before you've killed the bear")—an admonition against over-optimism. By the time of the South Sea Bubble of 1721, the bear was also associated with short selling; jobbers would sell bearskins they did not own in anticipation of falling prices, which would enable them to buy them later for an additional profit.
Another plausible origin is from the word "bulla" which means bill, or contract. When a market is rising, holders of contracts for future delivery of a commodity see the value of their contract increase. However in a falling market, the counterparties—the "bearers" of the commodity to be delivered—win because they have locked in a future delivery price that is higher than the current price.
Some analogies that have been used as mnemonic devices:
