A bull market cycle that spans or falls within a very long upward trend. Such a cycle features the characteristics of both secular cycles and bull markets. In other words, it extends over a very long bull market (ten years or more with bumps and wiggles all over).

In a secular bull market cycle, buy-and-hold is the best strategy: buying and holding securities, where price appreciation contributes to most of the gains as long as the cycle persists. However, once a secular bear market cycle begins, buy-and-hold will be counterproductive, and other short-term market tactics may be an optimal course of action.
