Below is a visualization of the longest bull markets in the US since the 50's.
Ranking the Bulls
The chart below, shows every bull market since WWII, including the top six which are covered in more detail:
*Still in progress.
By looking at duration, total rate of return, and annualized rate of return, it really gives a sense of how these bull markets compare.
The current run, which will soon become the longest, didn’t have the same level of intensity as other high-ranking bull markets. Critics would say that it was artificially propped up by ultra-low rates, QE, and other government actions that will make the market ultimately less robust heading forward.
Regardless, the current run ranks in fourth place among the markets above in terms of annualized return.
What Ended Each Bull?
The market psychology behind bull and bear markets can be fascinating.
Below we look at the events credited with “ending” each bull market – though of course, it is actually the actions of investors (buying or selling) that ultimately dictates market direction.
1. The Great Expansion The bull run lasted 9.5 years, ultimately capitulating when the Dotcom Bubble burst. From the span of June 1999 and May 2000, the Fed raised interest rates six times to try and get a “soft landing”. Market uncertainty was worsened by the 9/11 attacks that occurred the year after.
2. The Post-Crisis Bull Run Still ongoing…
3. The Post-War Boom This boom occurred after WWII, and it ended in 1956. Some of the sources we looked at credited the launch of Sputnik, Eisenhower’s heart attack, and the Hungarian Revolution as possible sources of market fear.
4. That ’70s Growth The Iranian Revolution, the 1979 Energy Crisis, and the return of double-digit inflation were the factors blamed for the end of this bull.
5. Reagan Era This bull market had the highest annualized return at 26.7%, but the party came to an end on Black Monday in 1987 – one of the most infamous market crashes ever. Some of the causes cited for the crash: program trading, overvaluation, illiquidity and market psychology.
6. The Hot Aughts Stocks did decently well during the era of cheap credit and rising housing prices. However, the Financial Crisis put an end to this growth, and would cut the DJIA from 14,000 points to below 6,600 points.
