Primary trends include bull markets and bear markets. The bull market is a situation where investors buy in order to increase capital gains in the future. In a bear market, on the other hand, the investors anticipate losses and therefore they are obliged to sell. Price fluctuation is an important tendency of an open market. The Gross Domestic Product(GDP) and stock prices are on the rise during a bull market. A bear market exhibits negative trends; it can also be a prelude to recession.
Secular market trends are long-term. They usually remain for a period of five to twenty five years. Many primary trends sequentially arranged result in a secular market trend. In such case, the bull markets are bigger and a bear market does not erase the gains of the previous bull market. In secular bear markets, the duration of a bull market is smaller.
