4 Ways Increasing the volatility of the stock market is changing the way investors trade

  • The stock market has been deceived so far in 2025, starting with sharp profits and tanking lately.
  • A gauge of expected market instability is the highest that has been per month.
  • A managing director at CME Group sets four ways of increasing instability has changed trading habits.

It has been a rolling trip to the shares so far in 2025.

After the source in a 4% profit in the first three weeks of the year, S&P 500 fought. After a 2% decrease on Thursday, the standard index has now decreased 7% since reaching levels of all time in mid -February.

Promoting movements has been a mixture of fear of contagious inflation, tariff threats, he’s competition and geopolitical risks.

Meanwhile, the CBOE – or VIX instability index, commonly referred to as a stock market fear, which looks at the expected shakes of 30 days in the future – decreases at its highest level since December. The stable theme is that the shares are particularly unstable now.

Paul Woolman, a managing director at CME Group, says the growth of market gyms over the past two years have prompted explosive appetite for options and future.

“The last few days, when the market is hiding, we see volumes raised because people are forced to risk managing and responding to that news flow,” he said, pointing out that traders are increasingly using derivative strategies to make those movements.

Detailed below are four ways investors have adapted their approaches in response to an increasingly volatile market environment:

(1) a move to shorter options with duration

For institutional investors, this implies a displacement from quarterly contracts in week, where volumes have been prominent, noted Woolman. Meanwhile, the retail favorite has been to go even shorter, betting for zero days for expiration options (0dte), which are dangerous contracts that expire on the same day to be issued.

Woolman said one reason for the change is that traders are likely to look for a lower premium than they can find with a longer duration contract, and rather move to the cheaper, shorter ones. Second, such an approach allows them to hold stronger positions and more control in an unsafe environment.

“Many institutional clients and potentially retail customers want to be really accurate when they are taking an option position,” Woolman said. “Sometimes they are targeting a specific risk of events so that they are economic numbers or profits or any other events, such as election events and such things.”

2. A move to the most sophisticated packages of options

Traditionally, the most basic strategies have been to buy and sell calls or set options in the main indices, something that reaches a direct direction. However, packages of options that spread exposure or double the obedience are becoming increasingly popular.

An example of those packets includes vertical spread, which are options for options for a fundamental asset that are either a call or set, but have different strike prices in the same expiration. It is a trade that reflects the strong attitude of a dealer that a price will move in an expected direction.

Sliding are also gaining popularity for less directed beliefs and more neutral positions that benefit from instability. In this position, a trader buys a call and set the strike at the same price and expiration date in a basic asset to promote instability in both directions. Another popular neutral position has been drowning when a trader buys or sells a call and sets different strike prices at the same expiration.

(3) Increased retail appetite for Micro e-mine options and partial options

These and the future options are about 10th the size of the parent mini-contracts and have been extremely successful in drawing individual traders, noted Woolman. Since they are more accessible and bitten size, this enables them to be included in trading applications like Robinhood, something he says has created growth.

(4) Increasing interest on subsequent contracts

Woolman says the activity has chosen in the markets of options and the future outside regular daily trading.

“As that news strikes, clients want to react and be able to trade about it. And we have definitely seen an increased trend of people who want to trade and manage their risk in real time,” Woolman said.

The table below shows the dates that saw the highest volumes of all time on the equality index options that follow S&P 500, Nasdaq 100 heavy technology, The Dow, and Russell 2000 in the post -time trading between 6 pm and 9am.

The fact that five of the top 10 days have come in the last year shows how demand for these products has accelerated along with market instability.
