The 'Tech bubble' burst on approximately Aug of 2000 and lost ground until Sept. of 2002.
The S&P Index dropped from approx. 1512 . to 763. A loss of roughly 50%
That bear market lasted roughly 756 Days or 2.07 years.
From the height of the market gains of Aug 2000 through the drop of that bear market, and the rise of the next bull run, it would've taken you 7 1/2 years to get back where you started.
The next Bull market after the tech crash ran from mid Feb. 2003 until approx. Sept of 2007. 1659 days or 4.5 years and gained back roughly 98% of what was lost.
At the end of that bull run was the Housing bubble!
The market dropped from approx.1565 to 664 for a whopping loss of around 58%!
The Housing bubble bear market lasted from Sept. of 2007 to around Feb of 2009. Roughly 490 Days, or 1.34 years.
Life was good and the markets chugged along from Feb 2009 through Sept. 2018.
That bull run was about 34,720 days or almost 9.5 years (from my graph:).
The market ran up from around 665 to a high of 2982 for an approx. increase of 347%.
The market correction of 2019 graph should be whipped out in a jiff . Stay tuned.
If we averaged in the length of time, and depth of loss, in the last two S&P 500 bear market cycles; we'd end up with the S&P being at roughly 1370 in July of 2020.
It's currently at 2596, which would mean a 47% drop from where we are now : )
