From Tuesday (3), those operating on B3 will have a longer trading session. According to Seu Dinheiro, spot shares will now be traded from 10am to 5:55pm, compared to the previous closing at 5pm, and the change also extends to futures, options and structured futures linked to indices, commodities and the dollar.

According to Your Money, the reason is the end of daylight saving time in the United States. According to InfoMoney, the time change also involves the United Kingdom and Germany, which end daylight saving time on October 25th, while the US is expected to do the same on November 1st. As these countries change time on different dates, the adjustment of the Brazilian stock market was designed in stages.

The calendar is not unique. According to InfoMoney, contracts linked to European markets already changed on October 26, last Monday. Shares and derivatives in general move to the new timetable on November 3rd, next Tuesday.

Closing also takes on new stages. For shares, funds and fractional markets, trading closes at 6:45 pm. In options, trading lasts until 5:55 pm, with a closing call until 6:15 pm and closing at 6:45 pm. Seu Dinheiro also informs that the closing call for shares takes place between 5:55 pm and 6:00 pm, and that the cancellation of offers has been extended until 6:45 pm.

What is at stake is the routine of those who watch the end of the afternoon. With a later closing, investors need to check brokerage times, platforms and scheduled orders, as each type of asset follows a different window. The texts consulted do not provide projections of impact on prices.

What changes for the investor

For those who trade stocks, the main difference is the extra trading time, which expands the window to react to end-of-day news. For those who trade derivatives, care is on the agenda: the change occurs on two dates and affects index, commodity and dollar contracts, which requires checking the time of each contract before the session. The reports do not quantify any effect on liquidity or volatility, and this text does not make price forecasts or buy or sell recommendations.
