At the lowest point of the financial crisis in the late 2000s, it felt like the U.S. economy might literally fall apart. The economy was in the midst of a deep recession. The housing market was collapsing. The unemployment rate briefly topped 10%.
To say the least, it sure didn't feel like the best time to be buying stocks.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »
At its lowest point on March 9, 2009, the S&P 500 (SNPINDEX: ^GSPC) closed at 676.53. The index wouldn't hit a new all-time high again until 2012.
But in hindsight, it turned out to be one of the best buying opportunities ever.
As of Sept. 10, the S&P 500 closed at 7,591.70. If you had bought the index at the March 2009 market low, your investment would have gained a staggering 1,030%. Add in reinvested dividends and the total return climbs to 1,470%!
Based on this, a $5,000 investment made at the Great Recession low would be worth around $56,690. With reinvested dividends, the account balance would be $78,510.
These numbers prove that bear markets and once-in-a-generation catastrophes are unquestionably painful to experience. But they can also be generational buying opportunities if you have the stomach to take advantage of them.
Nobody knows when a market bottom may occur. The biggest takeaway from this example is that if you have a long-term time horizon and don't need the money for years or even decades, continuing to invest in the S&P 500 as part of a systematic and consistent plan is usually the best course of action.
Even when conditions look historically bleak, there's always an opportunity hiding in the darkness.

Four leading AI models discuss this article
Opening Takes
“Long-term exposure to the S&P 500 remains compelling, but the outsized 2009-like gains are unlikely to repeat in today’s higher-valuation, tighter monetary regime.”
The article cherry-picks the 2009 bottom as proof that buy-and-hold in the S&P 500 is a generational wealth machine. But that rebound followed unprecedented QE, ultra-low rates, and a tech-driven upside cycle that may not repeat. Today valuations are elevated, rate normalization looms, and earnings trajectories are less clear amid macro uncertainty. The piece relies on reinvested dividends, ignores taxes/fees, and uses survivorship-biased stock-picks (Stock Advisor) to imply perpetual outperformance. It glosses over regime shifts—AI-driven productivity, debt load, and geopolitical risks—that could alter risk/return dynamics for broad-market bets.
Regime risk: if rates stay higher for longer and growth slows, the current ‘generational’ gains from 2009 are unlikely to repeat, and passive indexing could underperform selective, higher-quality bets.
“Historical recovery data is a poor predictor of future performance because it ignores the current valuation premium and the shift in monetary policy regimes.”
The article uses hindsight bias to peddle a classic 'survivorship' narrative. While the 1,470% total return since March 2009 is mathematically accurate, it ignores the psychological and liquidity constraints that force investors to sell during systemic crises. The piece conveniently pivots from index investing to a 'stock picking' pitch, which is a red flag. The structural reality is that we are currently trading at a forward P/E of roughly 21x, a significant premium to historical averages. Relying on the 2009 bottom as a roadmap for future 'buy the dip' strategies ignores current valuation compression risks and the reality that the Fed's QE-fueled liquidity tailwinds of the last decade are not guaranteed to repeat.
The strongest case against my skepticism is that secular growth in AI and cloud infrastructure creates a 'new normal' for valuations, potentially rendering historical P/E multiples obsolete for top-tier tech leaders.
“The article conflates a historically exceptional 15-year bull run with a replicable strategy, obscuring that most investors cannot identify market bottoms in real time and that future returns will likely be far more modest than 1,470%.”
This is survivorship bias masquerading as investment wisdom. Yes, $5K at the 676 S&P low became $78.5K with dividends—but the article omits critical context: (1) March 2009 wasn't obviously the bottom; many bought in late 2008 and got crushed further; (2) the 15-year window captured unprecedented monetary stimulus, near-zero rates, and tech's structural dominance—conditions unlikely to repeat; (3) the 1,470% return includes the 2010-2021 period, which was exceptional, not normal; (4) the article's real pitch is Stock Advisor's 950% average return, which cherry-picks winners like Netflix and Nvidia—not representative of typical subscriber outcomes.
The strongest case against my skepticism: systematic dollar-cost averaging into broad index funds during crashes has historically been the most reliable wealth-builder for retail investors, and this article's core message—don't panic-sell in crises—remains sound regardless of survivorship bias.
“The 2009 buying opportunity was defined by depressed valuations that no longer exist, so similar percentage gains are unlikely to repeat from current levels.”
The article correctly calculates the S&P 500's 1,030% price return and 1,470% total return from the March 9, 2009 close of 676.53 to 7,591.70 as of Sept 10, turning $5,000 into roughly $78,500 with dividends. Yet it presents this as proof that systematic long-term indexing is usually optimal even in bleak conditions. Missing is any discussion of valuation starting points: the 2009 trough occurred at roughly 10x forward earnings amid forced deleveraging, while today's index trades near 22x with higher profit margins already priced in. Future drawdowns may not deliver equivalent multiples expansion.
Even from elevated multiples, continued earnings growth and productivity gains could still compound at mid-single-digit real returns, making the timing critique irrelevant for true multi-decade holders.
The Debate
Responding to Gemini
“Higher discount rates and regime shifts threaten broad multiple support, so buy-the-dip in the index isn't a given even with AI-led productivity.”
Gemini's forward P/E focus ignores a regime-shift risk that makes 2009's rebound a poor blueprint today. AI-driven productivity may aid select leaders, but a sustained rise in discount rates could compress multiples and force an earnings-driven re-rating, even with strong growth. The article's reliance on Stock Advisor's outsized returns and survivorship bias weakens the case for universal buy-the-dip. A fresh worry: higher financing costs and tighter liquidity, not just valuations, threaten the upside.
Responding to Grok
“Structural fiscal deficits and rising long-term yields have replaced monetary policy as the primary constraint on future index returns.”
Grok and ChatGPT focus on valuation compression, but you are all missing the fiscal dominance factor. We are no longer in a period where the Fed can simply pivot to save the market; the massive Treasury issuance required to fund deficits creates a 'crowding out' effect. Even if AI productivity gains materialize, higher real yields on the long end of the curve will act as a structural headwind that 2009-2021 never faced. The 'buy the dip' thesis is broken by this debt-supply reality.
Responding to Gemini
“Fiscal dominance matters most not as crowding-out, but as a source of *unanchored* discount rate volatility that earnings forecasts can't hedge.”
Gemini's fiscal dominance argument is the sharpest risk surfaced so far, but it conflates two separate problems. Treasury crowding-out raises real yields, yes—but that's a *valuation* compression story, which ChatGPT and Grok already covered. The real tail risk Gemini misses: if deficits force the Fed to monetize or rates spike unpredictably, equity duration risk explodes regardless of earnings growth. That's different from 'multiples compress'—it's 'cash flows become unmoored from discount rates.' Nobody's quantified that tail yet.
Responding to Claude
“Today's 22x multiple embeds longer duration than 2009, so fiscal shocks will amplify losses beyond Claude's scenario.”
Claude's duration-risk tail under monetization pressure links straight to starting valuations. At 22x forward earnings the index already prices in extended cash-flow duration from tech leaders, so any fiscal-driven rate spike would trigger sharper re-rating than 2009's 10x trough allowed. That compounds the crowding-out effect Gemini noted and raises the hurdle for passive indexing to deliver equivalent real returns.
