What it is:
A major downtrend, or bear market, is when financial assets and markets -- as with the broader economy -- fall steadily for an extended period of time.
How it works (Example):
A major downtrend is when each successive decline of the primary trend carries the market to lower lows and lower highs, lasting from several months to several years. This is illustrated in Figure 1 below.
As you can see in the Figure 1, High 5 is lower than the previous high and Low 4 is lower than the previous low.
Within a major downtrend, several secondary reactions may occur against the trend, lasting for a few days, weeks or even months, but they don't necessarily change the definition of the overall trend. These movements are considered micro trends, such as daily movements and other short-term price fluctuations.
If a rally doesn’t succeed in breaking through the previous high and the market subsequently declines to fall below a previous low, the price movement is still considered a major downtrend.
Why it Matters:
It is difficult for investors to precisely time major downtrends. That's because markets often rise higher than most investors and analysts anticipate -- and sometimes fall lower than they could possibly fathom.
