The VIX, or Volatility Index, is a widely followed measure of expected market volatility over the next 30 days, based on S&P 500 options pricing.
Often referred to as the “fear gauge,” the VIX reflects how much traders anticipate market swings, though it does not indicate direction.
Rising VIX levels suggest growing uncertainty, while falling levels point to calmer sentiment.
Traders use the VIX and related indexes to assess risk, interpret market mood, and guide strategy.
While the VIX itself cannot be traded directly, products like futures, options, exchange-traded products (ETPs), and Contracts for Difference (CFDs) allow market participants to gain exposure to volatility movements.
Understanding how the VIX behaves during market events, and how it compares with similar instruments, can help traders build a more complete view of sentiment and risk conditions.
Key points:
The VIX, or volatility index, is one of the most-watched measures on Wall Street.
It shows how much movement traders expect in the S&P 500 over the next 30 days, based on real-time option prices.
Often called the “fear gauge,” the VIX rises when uncertainty is high and drops when markets feel steadier.
A high reading means traders expect bigger swings, while a low reading points to calmer trading.
It does not predict whether prices will go up or down, only the size of potential moves.
The VIX is the best known of these indexes, but not the only one.
Similar measures exist for the Nasdaq, Dow Jones, and other global markets.
Together, they give a quick view of sentiment and how much risk is being priced in. This guide is a practical resource for traders.
It explains what the VIX is, why it’s important, and how it compares with other fear gauges so you can better understand market sentiment.
The VIX comes from the prices of S&P 500 options.
These are contracts traders use to protect against moves in the index or to speculate on them.
When those option prices rise, it usually means traders expect bigger swings ahead. This is where implied volatility comes in.
Implied volatility isn’t what’s already happened, but what the market thinks will happen.
The VIX takes a wide set of option prices, runs them through a formula, and turns the result into a single number.
That number is quoted as a yearly percentage, but it represents the market’s best guess of volatility over the next month.
For example, a VIX reading of 20 means the market expects about 20 per cent annualized volatility.
Over a 30-day window, that translates to roughly plus or minus 5.8 per cent using the square root of time rule. This helps avoid the mistake of reading the VIX level as a direct monthly percentage.
Here is how most people read the levels:
These ranges are commonly used guidelines, not strict rules.
The VIX has spent long stretches below 20 without major problems, so it’s important to read levels in their market context.
You can see this play out during major world events.
The VIX shot above 80 in late 2008 during the financial crisis. It hit similar levels in March 2020 as COVID-19 spread. Those were extreme cases.
Most of the time, the VIX sits somewhere between the mid-teens and mid-twenties.
When you look at the VIX, start simple. The higher the number, the more uncertainty is being priced in.
There is also a pattern between the VIX and the S&P 500.
The two usually move in opposite directions.
When the index sells off, the VIX tends to climb because more people buy puts for downside protection.
When the index rallies, the VIX often drifts lower.
Some traders also look at the VIX as a contrarian signal.
When fear is extreme and the VIX spikes, it can line up with market bottoms.
When the VIX is very low, it can mean traders are too complacent.
These are tendencies, not rules. The VIX does not predict timing, only the level of expected swings.
If you see the VIX rising quickly, it is a sign that markets are pricing in more turbulence.
You can use that knowledge to think about how much risk you are carrying and whether your portfolio is set up for larger daily moves.
Some investors also use volatility products or index CFDs to hedge exposure.
Remember, these are derivative instruments.
Trading them involves speculation, and you do not own the underlying assets.
The VIX is a calculation, not a stock or index you can buy.
To trade it, you need products linked to it.
The most direct are VIX futures.
These contracts let you speculate on where the VIX will be on a future date.
On most global exchanges, VIX futures are quoted under the ‘VX’ ticker followed by a contract code, such as VXU25.
Some brokers simplify this and display the instrument as ‘VIX’ in their interface.
The important point is that the VIX index itself cannot be traded directly.
What you access are futures, options, or CFDs linked to it.
You can also trade options on VIX futures.
They give you the right, but not the obligation, to buy or sell a futures contract at a set price.
These contracts are often used by more advanced traders because pricing is complex.
Exchange-Traded Products (ETPs) are another way to gain exposure.
Popular examples include VXX and VIXY. They are built to track baskets of VIX futures.
That makes them easier to trade, but they come with a catch.
When these products roll contracts each month, they face contango or backwardation.
Contango is when longer-term futures cost more than near-term ones.
Over time, this can erode the value of the product.
This erosion is particularly problematic for long-term holding.
Short-term traders may not notice the same impact, but the effect becomes significant over weeks or months.
Backwardation is the reverse situation, where near-term contracts cost more, and it can benefit the holder.
These effects mean VIX ETPs rarely move in perfect step with the spot VIX index.
All of these instruments are risky.
They can swing sharply, and performance may not match expectations.
Whether you look at futures, options, or CFDs, you are speculating on price.
You do not own the underlying asset. CFDs on volatility indices, such as those offered by PU Prime, are broker-created contracts.
They mirror price movements but are different from official exchange-listed futures or options.
Volatility-based instruments such as VIX futures, options, exchange-traded products (ETPs), and CFDs provide traders with an additional way to approach the market.
These products allow positions to be based on expected price movement rather than direction alone.
Key Benefits for Traders:
VIX-linked instruments offer practical applications for those who monitor volatility and sentiment closely.
They are often used by traders who want to respond to changing market conditions with targeted tools.
The VIX is the most widely followed volatility index, but markets track several related measures to capture sentiment in different areas.
For the Nasdaq 100, there is the VXN. It often moves more sharply than the VIX because technology stocks tend to be more volatile.
For small-cap stocks, traders look at the RVX, which tracks expected volatility in the Russell 2000. The VXD serves the same role for the Dow Jones Industrial Average.
Globally, you will also find measures like Germany’s VDAX or Hong Kong’s VHSI.
Beyond volatility indexes, there are sentiment tools built from other data.
The CNN Fear & Greed Index combines several inputs, including stock price momentum, option demand, and market breadth, into a single score.
The put/call ratio is another commonly watched number.
It compares the volume of put options to call options.
A high ratio suggests more demand for protection, while a low ratio suggests more optimism.
Each of these gauges has its own quirks, but together they give a fuller picture of how traders feel.
The VIX shows the broad S&P 500 view. VXN, RVX, and others add sector and regional color.
Put/call ratios and composite indexes show how traders are positioning.
Looking at them side by side can help you see whether fear is isolated in one corner of the market or spreading more broadly.
One of the clearest ways to see the role of the VIX is to look at how it moved during past shocks.
Take March 2020, when the COVID-19 pandemic sparked a global selloff.
As the S&P 500 dropped more than 30 per cent in just a few weeks, the VIX surged to above 80.
That was one of the highest readings in its history and showed just how much volatility traders expected in the month ahead.
For traders watching at the time, the spike signaled extreme fear.
Options prices were rising sharply because many investors rushed to hedge against more downside.
The VIX did not say whether markets would recover quickly or keep falling.
What it showed was that uncertainty was at its peak.
This type of move is what makes the VIX useful as context.
During calmer stretches, it often sits in the mid-teens.
When it shoots higher, you know that expectations for daily swings are much larger.
Traders can use that knowledge to think about risk levels in their portfolios.
Some may decide to reduce exposure. Others might look at volatility products or index CFDs to speculate on price swings.
None of these is guaranteed, but the VIX makes clear when the market mood has shifted.
The same pattern played out during the 2008 financial crisis.
As banks failed and credit markets froze, the VIX again jumped above 80.
Both episodes show that the index tends to spike when markets face sudden, severe stress.
To wrap it all up, the VIX gives you a clear view of how much movement traders expect in the S&P 500 over the next 30 days.
It does not predict direction, but it shows when uncertainty is rising or falling.
Other fear gauges, such as the VXN for the Nasdaq or the RVX for small caps, add more detail. Sentiment tools like the put/call ratio or the CNN Fear & Greed Index provide extra context.
The key takeaway is that these indicators work best as part of a bigger picture.
On their own, they are not buy or sell signals.
Combined with technical analysis, fundamentals, and sound risk management, they can help you understand the environment you are trading in.
If you want to see how volatility products trade in practice, you can explore VIX futures and index CFDs on PU Prime’s platform.
As with any derivative, trading them involves speculation, and you do not own the underlying assets.
Volatility analysis doesn’t mean finding certainty, but being aware of the market’s expectations and adjusting your decisions with that knowledge in mind.
The VIX plays a valuable role in helping traders interpret market sentiment and adjust their strategies.
While it cannot predict direction, its movements offer insight into the level of expected price swings across the broader equity market.
When used alongside other indicators and sound risk management practices, the VIX can help you better understand the trading environment and prepare for potential volatility.
Whether you’re monitoring sentiment shifts, managing exposure, or exploring speculative opportunities, staying informed about volatility trends is a key part of trading in dynamic markets.

What is a good VIX level to buy stocks?
There is no set level that signals a good time to buy.
A lower VIX usually reflects calmer markets, while a higher VIX shows more uncertainty.
Some traders see very high readings as a sign of fear that may later ease, but the VIX is not a timing tool and should not be treated as a buy signal.
Can the VIX predict market crashes?
No, the VIX does not forecast direction.
It measures expected volatility over the next 30 days based on option prices.
While it often rises before or during periods of stress, it does not predict whether the market will fall or recover.
How is the VIX different from historical volatility?
Historical volatility looks backward at how much an index has moved over a given period.
The VIX looks forward by using option prices to estimate the expected movement.
One shows what already happened, the other reflects market expectations.
What are the main risks of trading VIX ETPs?
VIX exchange-traded products track futures, not the VIX itself.
Because they roll contracts, they are affected by contango and backwardation.
This can cause performance to diverge from the spot index, especially over longer periods.
They can also move sharply in short bursts.
As with any derivative, you are speculating on price changes and do not own the underlying asset.
