A VIX spike above 20 is often seen as a warning sign that fear is entering the stock market. But does elevated volatility actually predict poor future returns? In this article, we’ll examine historical VIX data, analyze how the S&P 500 has performed after volatility spikes, and explore what periods of heightened fear have historically meant for traders and long-term investors.

---

Often referred to as Wall Street’s “fear index,” the VIX measures expected stock market volatility and tends to spike during periods of uncertainty, market corrections, and investor panic.

While elevated volatility can feel uncomfortable, history shows that fear and opportunity often go hand in hand.

Since 1990, the VIX has averaged roughly 19.5, meaning a move above 20 signals that market participants are becoming increasingly concerned about future price swings.

In some extreme cases, the VIX has surged above 80, including during the 2008 Financial Crisis and the 2020 COVID crash.

But what actually happens after the VIX rises above 20?

In this article, we’ll examine the historical data, explore what elevated volatility has meant for investors in the past, and look at how the S&P 500 has performed following periods of heightened fear.

Quick Answer: What Happens After the VIX Spikes Above 20?

Historically, a VIX reading above 20 has signaled elevated investor fear and market uncertainty, but it has not necessarily been a bearish signal for long-term investors. While the VIX often rises during market corrections and periods of volatility, history shows that many of the strongest stock market recoveries have occurred after volatility spikes. In general, higher VIX readings have been associated with increased short-term risk, larger price swings, and, in many cases, stronger long-term returns as market fear eventually subsides.

What Is The VIX?

The CBOE Volatility Index (VIX) is a real-time measure of expected stock market volatility over the next 30 days based on S&P 500 options prices. So in essence, the VIX reflects how much volatility investors expect in the near future.

Since its introduction in 1990, the VIX has averaged approximately 19.5, making a reading above 20 a commonly watched threshold for elevated market fear.

During periods of calm, the VIX often trades between 10 and 20, while readings above 30 typically signal significant uncertainty and market stress.

---

Historically, sharp spikes in the VIX have often coincided with major market corrections, bear markets, and periods of investor panic.

Because the VIX tends to move inversely to the stock market, traders and investors closely monitor it for clues about market sentiment, risk appetite, and potential opportunities created by heightened volatility.

---

How Often Does The VIX Rise Above 20?

Many investors view a VIX reading above 20 as a sign that fear is entering the market.

While headlines often make elevated volatility sound unusual, the reality is that the VIX rises above 20 far more often than most investors realize.

Historically, higher VIX readings coincide with significant market stress, while lower readings coincide with a calmer market environment.

Looking at historical data, the VIX has spent a substantial portion of its history above the 20 level.

In fact, one long-term study found that the VIX closed above 20 on approximately 39% of trading days, highlighting that elevated volatility is not nearly as rare as many investors believe.

Periods of sustained market stress or uncertainty can keep the VIX elevated for months at a time.

For example, during the Financial Crisis, the VIX remained above 20 for an incredible 331 consecutive trading days, the longest streak on record.

During 2020, the VIX closed above 20 on 86% of all trading days, reflecting the extraordinary uncertainty created by the COVID-19 pandemic.

And even more recently, President Trump announced sweeping “Liberation Day” tariffs on April 2, 2025, triggering one of the sharpest volatility spikes in years

Less than a week later, the VIX peaked at approximately 52.33 on April 8, 2025, after surging to around 60 intraday, marking its highest level since August 2024 and one of the highest readings since 2020.

What’s most striking about the tariff-related VIX spike is that it took only five days for the VIX to peak, and another 14 days to revert to the level from which it started.

There are countless examples like this from throughout history.

But the key takeaway is that a VIX reading above 20 should not be viewed as a rare warning sign. Instead, it is often a normal feature of market corrections, economic uncertainty, and periods of heightened volatility.

The more important question is not how often the VIX rises above 20—but rather what has historically happened to stocks after it does.

What Happens After The VIX Crosses Above 20?

While a VIX reading above 20 is often viewed as a warning sign, historical data suggests that elevated fear has frequently created opportunities for long-term investors.

Since 1990, the first VIX close above 20 following at least 20 trading days of calm market conditions has been followed by an average S&P 500 gain of 13.84% over the next year, while 90% of signals produced positive returns six months later.

Historical S&P 500 Performance After A VIX Crosses Above 20

To test whether elevated volatility has historically been bullish or bearish for investors, I analyzed every instance since 1990 where the VIX closed above 20 after spending at least 20 consecutive trading days below that level.

A total of 12 signals met this criteria.

The results suggest that while a VIX spike above 20 often coincides with fear and uncertainty, the stock market has historically performed surprisingly well over the following months and years.

Average S&P 500 Forward Returns After VIX Spikes

The strongest statistic I found was that the six-month positive rate. Historically, 90% of VIX >20 signals resulted in positive S&P 500 returns six months later.

Perhaps even more surprising, the average 12-month return following these signals was 13.84%, which is higher than the long-term average annual return of the S&P 500.

This supports the same data I wrote about in my related article, “What happens after the S&P 500 hit a new all-time high?,” where I explain that new highs often signal a strong market, and should not be seen as a warning of an imminent market correction.

Best and Worst Outcomes After A VIX Spike

Of course, not every volatility event leads to immediate gains.

While the averages are encouraging, investors should remember that elevated volatility often accompanies periods of genuine economic uncertainty and market stress.

The table below highlights the best and worst outcomes observed during the study.

Historical Extremes

These results highlight an important point: A VIX reading above 20 is not a guarantee that stocks will immediately move higher.

In some cases, markets continued falling in the weeks and months that followed.

However, the historical evidence suggests that elevated fear has often marked periods when long-term returns became increasingly attractive.

Should You Buy Stocks When The VIX Spikes?

The VIX tends to spike when investors become fearful.

But the thing is, by the time the VIX rises above 20, markets have often already experienced a meaningful decline, negative headlines dominate financial news, and investor sentiment has deteriorated.

So, not surprisingly, some of the best buying opportunities have emerged during these periods of elevated fear.

This isn’t to say you should buy stocks every time the VIX spikes above 20.

But it does help explain why major volatility events such as the 2008 Financial Crisis, the 2020 COVID Crash, and the 2025 Tariff Panic were eventually followed by powerful market recoveries despite widespread pessimism at the time.

---

Does A High VIX Signal A Market Bottom?

Not necessarily. While extreme VIX spikes often occur near major market bottoms, they are better viewed as signs of peak fear rather than precise buy signals.

Historically, some of the market’s most significant bottoms have occurred when the VIX surged well above 20, but investors rarely knew the bottom was in until months later.

The common thread across these events wasn’t the VIX itself—it was a shift in investor sentiment, policy responses, or improving economic conditions.

Here are a few examples from throughout history when the VIX spiked to extreme levels and when the market eventually bottomed and recovered.

1998 LTCM Crisis

• The collapse of Long-Term Capital Management (LTCM) triggered widespread fears about systemic financial risk.
• The VIX surged above 40 as investors rushed to reduce risk.
• The market bottomed shortly after the Federal Reserve coordinated efforts to stabilize financial markets.
• Once panic subsided, the S&P 500 resumed its bull market and gained more than 20% over the following year.

---

2008 Financial Crisis

• The VIX remained elevated for months and eventually surged above 80 during the worst phase of the crisis.
• Contrary to popular belief, the first VIX spike did not mark the bottom.
• The market continued falling until March 2009 as bank failures and recession fears intensified.
• The eventual bottom was marked by improving credit conditions, government intervention, and signs that the financial system would survive.

2020 COVID Crash

• The VIX reached an all-time closing high of 82.69 in March 2020.
• The S&P 500 fell more than 30% in just a few weeks.
• Massive fiscal stimulus, emergency Federal Reserve actions, and improving investor confidence helped stabilize markets.
• The March 2020 VIX spike occurred almost simultaneously with the market bottom and was followed by one of the strongest bull markets in history.

2022 Bear Market

• Inflation surged to multi-decade highs and the Federal Reserve aggressively raised interest rates.
• The VIX repeatedly moved above 30 throughout the year.
• Unlike 2020, there was no single panic event that marked the bottom.
• The market ultimately stabilized as inflation began moderating and investors started anticipating a slower pace of rate hikes.

2025 Trump Tariff Panic

• President Trump’s April 2025 tariff announcement triggered one of the sharpest volatility spikes since the COVID crash.
• The VIX surged above 50 while the S&P 500 lost roughly $5 trillion in market value over two trading days.
• Investor sentiment improved after the administration announced a 90-day tariff pause.
• The VIX quickly retreated and stocks staged a powerful relief rally, demonstrating how rapidly market fear can reverse once uncertainty begins to fade.

---

The Common Pattern

Looking across these events, a clear pattern emerges:

• The VIX spikes when fear peaks.
• The market bottom is often formed when uncertainty begins to decline.
• Policy responses, improving fundamentals, and shifting investor sentiment typically matter more than the VIX level itself.

For that reason, a high VIX should not be viewed as a standalone buy signal.

However, history suggests that some of the best long-term investment opportunities have emerged when volatility was elevated and investor fear was widespread.

---

VIX Above 20 vs VIX Above 30

Another important takeaway from all this is that not all volatility spikes are created equal.

While a VIX reading above 20 signals elevated fear, a move above 30 typically indicates that investors are becoming significantly more concerned about market conditions.

To see whether higher fear levels produced different outcomes, I compared the performance of the S&P 500 following both VIX >20 and VIX >30 signals. The results suggest that VIX >30 events were considerably less common, but they did not consistently lead to stronger future returns.

While the sample size is limited, the results suggest that moderate fear has historically been more constructive for future stock returns than periods of extreme panic.

*Note: Results are based on signals identified from June 2021 through 2026 due to overlapping VIX and S&P 500 data availability.

While VIX readings above 30 often coincide with severe market stress, they can also occur when economic conditions are deteriorating rapidly, which helps explain the lower long-term success rate.

The takeaway is that a VIX reading above 20 has historically been a sign of opportunity more often than danger, while VIX readings above 30 represent a much more uncertain environment.

Final Takeaway – What Does VIX Above 20 Mean For Traders and Investors?

A VIX reading above 20 doesn’t guarantee that the market has bottomed, nor does it mean a crash is imminent.

What it does signal is a shift in market behavior where volatility expands, price swings become larger, and uncertainty increases.

The data in this study found that the first VIX close above 20 following an extended period of market calm was followed by an average 12-month S&P 500 return of 13.84%, while 90% of signals produced positive returns six months later.

While past performance never guarantees future results, history suggests that elevated fear has often rewarded disciplined investors willing to look beyond the headlines.

Still, the VIX is NOT a crystal ball. It’s a measure of sentiment.

Fear and volatility are inevitable parts of investing. History suggests that while elevated VIX readings often feel uncomfortable in the moment, they have frequently coincided with some of the market’s most attractive long-term opportunities.

Frequently Asked Questions

What does a VIX reading above 20 mean?

A VIX reading above 20 generally indicates elevated investor fear and market uncertainty. While readings between 15 and 20 are considered normal, a move above 20 suggests that traders expect larger-than-normal price swings in the stock market over the next 30 days.

Is a VIX above 20 bullish or bearish?

A VIX reading above 20 is often considered bearish in the short term because it reflects increased fear and volatility. However, historical data shows that elevated VIX readings have frequently been followed by strong long-term stock market returns, particularly after major market corrections.

What happens to stocks after the VIX rises above 20?

In my study of VIX signals since 1990, the first VIX close above 20 following at least 20 trading days below that level was followed by an average 12-month S&P 500 gain of 13.84%. Additionally, 90% of signals produced positive returns six months later.

How often does the VIX rise above 20?

The VIX has historically closed above 20 on approximately 39% of all trading days since 1990. While investors often view elevated volatility as unusual, VIX readings above 20 are actually a relatively common feature of market corrections and periods of uncertainty.

Does a high VIX signal a market bottom?

Not necessarily. While some major market bottoms have occurred during extreme VIX spikes, the VIX is better viewed as a measure of investor fear rather than a precise market timing tool. Market bottoms are often driven by improving economic conditions, policy responses, and shifting investor sentiment.

What is considered a high VIX reading?

Most investors consider:

• Below 15: Low volatility
• 15-20: Normal market conditions
• Above 20: Elevated fear
• Above 30: High fear and market stress
• Above 40: Extreme panic

Historically, readings above 30 and 40 have often coincided with major market corrections, bear markets, and financial crises.

What was the highest VIX reading in history?

The highest VIX reading on record was 82.69, reached during the COVID-19 market crash in March 2020. This remains the highest closing value in the history of the volatility index.

Should investors buy stocks when the VIX spikes?

A VIX spike alone is not a buy signal. However, history shows that periods of elevated fear have often created attractive long-term buying opportunities for disciplined investors. Rather than focusing solely on the VIX, investors should also consider valuations, economic conditions, and their overall investment strategy.

Why is the VIX called the Fear Index?

The VIX is often called the “Fear Index” because it measures expected stock market volatility using S&P 500 options prices. When investors become fearful and demand more downside protection, option prices rise, causing the VIX to increase.

Is a high VIX good for traders?

Many traders welcome higher VIX readings because increased volatility often creates larger price swings, stronger momentum, and more trading opportunities. However, higher volatility also increases risk, making proper position sizing and risk management even more important.
