Been digging into some interesting market history lately, and I came across something worth sharing. Everyone's curious about how long do bear markets last, especially when things get rough. So I decided to look at the actual data spanning back to 1950.

Here's what caught my attention: since 1950, the S&P 500 has experienced 11 legitimate bear markets (defined as 20%+ declines). The duration? All over the place. You've got the 1987 crash that bottomed in just 101 days, but then the 2000-2002 dot-com period dragged on for 929 calendar days. The 2008 Great Recession took 517 days. Even the 2020 COVID crash was relatively quick at 33 days. When you average it all out, the typical bear market takes around 389 days to find its bottom. That's roughly a year and three weeks.

What's interesting is the pattern shift over time. Before the mid-1980s, you had six bear markets crammed into just 25 years because information moved slowly and rumors spread like wildfire. Fast forward to now, and we've only seen four bear markets since 1987. Better information flow and automation have actually kept volatility more contained. But here's the trade-off: when modern bear markets do happen, they tend to last longer. The dot-com bubble and 2008 crisis both stretched well beyond historical averages.

So how long do bear markets last in today's environment? Probably longer than you'd hope, but the silver lining is what comes after. Every single crash throughout history eventually got wiped out by a bull market. Every single one.

If you're sitting through a downturn, three strategies can help. First, use dollar-cost averaging to edge into positions you believe in long-term, especially since most brokers ditched commission fees. Second, lean into dividend stocks because profitable, dividend-paying companies have weathered recessions before and historically crush non-dividend payers over long periods. Third, grab some defensive plays like utilities, consumer staples, and healthcare. These aren't glamorous, but they keep paying when everything else is burning.

The psychology is the hardest part. Watching unrealized losses pile up sucks. But patience during bear markets has historically been one of the best wealth-building moves you can make. The question of how long do bear markets last matters less than remembering that they always end.
