A market trend is a perceived tendency of financial markets 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 attempt to 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 trend can only be determined in hindsight, since at any time prices in the future are not known.
The terms “bull market” and “bear market” describe upward and downward market trends, respectively, and can be used to describe either the market as a whole or specific sectors and securities. The names perhaps correspond to the fact that a bull attacks by lifting its horns upward, while a bear strikes with its claws in a downward motion.
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 market gold price fell from a high of \$850/oz (\$30/g) to a low of \$253/oz (\$9/g); this was 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 a period of generally rising prices. The start of a bull market is marked by widespread pessimism. This point is when the “crowd” is the most “bearish”. The feeling of despondency changes to hope, “optimism”, and eventually euphoria, as the bull runs its course. This often leads the economic cycle, for example in a full recession, or earlier. An analysis of Morningstar, Inc. stock market data from 1926 to 2014 found that a typical bull market “lasted 8.5 years with an average cumulative total return of 458%”, while annualized gains for bull markets range from 14.9% to 34.1%.
India's Bombay Stock Exchange Index, BSE SENSEX, had a major bull market trend for about five years from April 2003 to January 2008 as it increased from 2,900 points to 21,000 points, more than a 600% return in 5 years. Notable bull markets marked the 1925–1929, 1953–1957 and the 1993–1997 periods when the U.S. and many other stock markets rose; while the first period ended abruptly with the start of the Great Depression, the end of the later time periods were mostly periods of soft landing, which became large bear markets. (see: Recession of 1960–61 and the dot-com bubble in 2000–2001)
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 smaller decline of 10 to 20% is considered a correction. Once a market enters correction or bear market territory, it isn't considered to have exited that territory until a new high is reached.An analysis of Morningstar, Inc. stock market data from 1926 to 2014 found that a typical bear market “lasted 1.3 years with an average cumulative loss of −41%”, while annualized declines for bear markets range from −19.7% to −47%.
A bear market followed the Wall Street Crash of 1929 and erased 89% (from 386 to 40) of the Dow Jones Industrial Average's market capitalization by July 1932, marking the start of the Great Depression. After regaining nearly 50% of its losses, a longer bear market from 1937 to 1942 occurred in which the market was again cut in half. Another long-term bear market occurred from about 1973 to 1982, encompassing the 1970s energy crisis and the high unemployment of the early 1980s. Yet another bear market occurred between March 2000 and October 2002. Recent examples occurred between October 2007 and March 2009, as a result of the financial crisis of 2007–2008. See also 2015 Chinese stock market crash.
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 identified retrospectively, as market participants are not aware of it at the time it happens. Thus prices subsequently fall, either slowly or more rapidly. 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.
The peak of the dot-com bubble (as measured by the NASDAQ-100) occurred on March 24, 2000. The index closed at 4,704.73. The Nasdaq peaked at 5,132.50 and the S&P 500 at 1525.20.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 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.
Some examples of market bottoms, in terms of the closing values of the Dow Jones Industrial Average (DJIA) include: The Dow Jones Industrial Average hit a bottom at 1738.74 on 19 October 1987, as a result of the decline from 2722.41 on 25 August 1987. This day was called Black Monday (chart). A bottom of 7286.27 was reached on the DJIA on 9 October 2002 as a result of the decline from 11722.98 on 14 January 2000. This included an intermediate bottom of 8235.81 on 21 September 2001 (a 14% change from 10 September) which led to an intermediate top of 10635.25 on 19 March 2002 (chart). The “tech-heavy” Nasdaq fell a more precipitous 79% from its 5132 peak (10 March 2000) to its 1108 bottom (10 October 2002).A bottom of 6,440.08 (DJIA) on 9 March 2009 was reached after a decline associated with the subprime mortgage crisis starting at 14164.41 on 9 October 2007 (chart).
Secondary trends are short-term changes in price direction within a primary trend. They may last for a few weeks or a few months. A short-term change like this may at the time be called a market correction. A correction is a short-term price decline of 5% to 20% or so. An example occurred from April to June 2010, when the S&P 500 went from above 1200 to near 1000. Some said this was the end of the bull market and start of a bear market, but it was not, and the market turned back up. A correction is a downward movement that is not large enough to be a bear market (ex post). Similarly, a bear market rally (sometimes called “sucker's rally” or “dead cat bounce”) is a price increase of 10% or 20% or so before prices fall again. 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 tracked a number of bear-market rallies since the late 1980s while experiencing an overall long-term downward trend. In January 2015, Malcolm Maiden called the Australian market a “meerkat market”, being timid with low consumer and business sentiment.
The price of assets such as stocks is set by supply and demand. By definition, the market balances buyers and sellers, so it is impossible to have “more buyers than sellers” or vice versa, although that is a common expression. In a surge in demand, the buyers will increase the price they are willing to pay, while the sellers will increase the price they wish to receive. In a surge in supply, the opposite happens. Supply and demand are varied when investors try to shift allocation of their investments between asset types. For example, at one time, investors may wish to move money from government bonds to “tech” stocks, but they will only succeed if somebody else is willing to buy government bonds from them; at another time, they may try to move money from “tech” stocks to government bonds. In each case, this will affect the price of both types of assets. Ideally, investors would wish to buy low and sell high, but they may end up buying high and selling low. Contrarian investors and traders attempt to “fade” the investors' actions (buy when they are selling, sell when they are buying). A time when most investors are selling stocks is known as distribution, while a time when most investors are buying stocks is known as accumulation. According to standard theory, a decrease in price will result in less supply and more demand, while an increase in price will do the opposite. This works well for most assets but it often works in reverse for stocks due to the mistake many investors make of buying high in a state of euphoria and selling low in a state of fear or panic as a result of the herding instinct. In case an increase in price causes an increase in demand, or a decrease in price causes an increase in supply, this destroys the expected negative feedback loop and prices will be unstable. This can be seen in a bubble or crash.
Investor sentiment is a contrarian stock market indicator. 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.
Investor Intelligence Sentiment Index: If the Bull-Bear spread (% of Bulls − % of Bears) is close to a historic low, it may signal a bottom. Typically, the number of bears surveyed would exceed the number of bulls. However, if the number of bulls is at an extreme high and the number of bears is at an extreme low, historically, a market top may have occurred or is close to occurring. This contrarian measure is more reliable for its coincidental timing at market lows than tops. American Association of Individual Investors (AAII) sentiment indicator: Many feel that the majority of the decline has already occurred once this indicator gives a reading of minus 15% or below. Other sentiment indicators include the Nova-Ursa ratio, the Short Interest/Total Market Float, and the put/call ratio.
