What does the framework of a bear market look like

Nasdaq during the years of the dot-com bubble burst
2000 to 2002
Total decline, -78%
Along the way, there were several decent rebounds
+35%
+12%
+25%
+41%
+45%
Each time it seemed like the bottom was in
Each time it was a trap
The harshest was that +45% wave
Just before the final collapse, it gave you a glimmer of hope
This is the skeleton of a bear market
It will throw out fierce rebounds, first shaking out the shorts
Then trick the bulls back in
And then continue to push down
