The stock market has experienced a number of setbacks during the past several decades.
Investing during stock market plunges allows you to buy quality companies at a discount.
Holding on to your best investments through volatility often yields outsized returns.
Have you ever wondered what would happen to your capital if you simply kept investing a modest sum into the S&P 500 (SNPINDEX: ^GSPC) every time the stock market had a meltdown?
Even without precisely timing the exact bottom of each crash, you'd still be looking at a pretty sweet pile of cash simply from investing during the thick of panic. That's the power of treating stock market slumps as opportunities rather than disasters. Let's walk through how this plays out and what smart investors can learn about buying the dip.
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 »

The stock market has experienced its share of rough patches during the past 75 years or so. For the sake of this analysis, I am specifically isolating events during which the S&P 500 dropped by 20% or more:
In each case, I'm assuming that the series of $1,000 investments was not made at the absolute rock-bottom close. To be realistic, I'm treating each outlay as being roughly 10% higher than the trough. That would equate to the following entry points and gains:
| Year | S&P 500 Entry Point | Implied % Gain | Implied Worth of $1,000 Investment |
|---|---|---|---|
| 1957 | 43 | 17,923% | $180,233 |
| 1962 | 58 | 13,262% | $133,621 |
| 1966 | 80 | 9,588% | $96,875 |
| 1970 | 76 | 10,097% | $101,974 |
| 1974 | 68 | 11,297% | $113,971 |
| 1982 | 113 | 6,758% | $68,584 |
| 1987 | 246 | 3,050% | $31,504 |
| 2002 | 855 | 806% | $9,064 |
| 2009 | 745 | 940% | $10,403 |
| 2020 | 2,460 | 215% | $3,150 |
| 2022 | 3,935 | 97% | $1,970 |

Here's the simple math behind the table. Each $1,000 investment divided by the entry price tells you how many "units" of the S&P you own. From there, I multiply those units by the current level of the S&P 500 -- about 7,750. In total, these 11 separate investments generated more than $750,000 in cumulative gains -- a return of more than 68-fold.
Market stumbles always have and always will happen. But every single time, one common theme emerges: The market eventually rebounds, and the S&P goes on to new highs.
One of the most common aspects of behavioral finance is to panic sell when the outlook is bleak. But if you remain calm and disciplined, smart investors can use these resets as a chance to buy quality companies at a discount. From there, exercising patience is the key as the market's long-term ascent does the heavy lifting for you.
The big takeaway here is simple: Don't run for the hills when things get ugly. Instead, use dips to your advantage, and let time and compounding do the hard work. The S&P 500 has a long, resilient history of recovering and moving higher. Over the course of a long-term time horizon, the market ultimately rewards those who stick around.
