What is the best time to trade stocks? Definition from Digimagg

In contrast to long-term investment strategies, trading typically adopts a short-term outlook. Traders acquire stocks not for gradual appreciation but for quick turnarounds, often within specific timeframes—ranging from a few days to a quarter.

Day trading, with its exceedingly short durations, scrutinizes analyses in hours, minutes, and even seconds. The timing of trades becomes a critical consideration.

Are there specific days of the week ideal for buying or selling stocks? Does an opportune time of year for purchasing stocks exist? What about the best month for buying or selling stocks?

In this article, we'll explore how to synchronize trading decisions with daily, weekly, and monthly trends.

Ideal times of day for buying or selling stocks

During the early morning, market activity and prices can experience significant fluctuations. The opening hours reflect all events and news releases since the previous closing bell, leading to heightened price volatility.

While skilled traders may capitalize on these patterns for quick profits, novices may incur substantial losses. For less experienced traders, it's advisable to avoid trading during these volatile hours, particularly within the first hour.

However, for seasoned day traders, the initial 15 minutes following the opening bell present prime opportunities, typically yielding some of the day's most significant trades based on initial trends.

The opening period (9:30 a.m. to 10:30 a.m. Eastern Time) often stands out as one of the most favorable hours for day trading, offering substantial moves in a short timeframe. Many professional day traders conclude their activities around 11:30 a.m. as volatility and volume diminish. Subsequently, trades become slower, with smaller movements and reduced volume.

If your day trading activities involve index futures like S&P 500 E-Minis or actively traded index exchange-traded funds (ETFs) such as the S&P 500 SPDR (SPY), trading can commence as early as 8:30 a.m. during premarket hours, tapering off around 10:30 a.m. Trading can extend until 11:30 a.m., provided the market continues to offer opportunities.

Midday typically represents the calmest and most stable period of the trading day. As investors await further news, and most of the day's announcements have already influenced stock prices, the market tends to stabilize. This period offers beginners an opportunity to place trades with slower action and potentially more predictable returns.

In the final hours of the trading day, volatility and volume surge once more. In fact, common intraday stock market patterns suggest that the last hour mirrors the first, with sharp reversals and significant movements, particularly in the last few minutes of trading.

From 3 p.m. to 4 p.m. ET, day traders often aim to close their positions or capitalize on a late-day rally, hoping that momentum will carry over into the next trading day.

Optimal day of the week for purchasing stocks

While some believe specific days yield consistently better returns, there's scant evidence supporting such a market-wide trend over time.

However, the notion persists that the first workday, Monday, offers favorable opportunities, known as the Monday effect or weekend effect. Traditionally, traders note a tendency for stock market declines on Mondays.

This phenomenon is attributed to the release of significant negative news over the weekend or investors' Monday blues as they return to work, particularly evident in early Monday trading hours.

Despite its prevalence, the Monday effect has largely diminished. Data indicates that while Mondays typically exhibit marginal negative returns for the S&P 500 from 2000 to June 2023, the effect is minimal.

Nonetheless, if you're considering purchasing stocks, Monday might still be preferable, potentially capitalizing on discounted opportunities.

Optimal day of the week for selling stocks

If Monday represents a favorable day for buying stocks, then Thursday or early Friday could be optimal for selling, preempting potential price declines. For those considering short selling, Friday might present an opportunity to initiate short positions (if stocks are priced higher), with Monday being the preferred day to cover shorts.

In the United States, Fridays before three-day weekends stand out as particularly promising. Positive sentiments preceding extended holiday weekends often lead to market upswings before these observed holidays.

Optimal month for purchasing stocks

The markets often exhibit robust returns during March, April, and July, followed by a decline in the fall months through winter, spanning from October to December. An observed phenomenon known as the January effect suggests that at the start of a new year, investors enthusiastically reenter equity markets, driving up prices, particularly for small-cap and value stocks, as described in "Stocks for the Long Run: The Definitive Guide to Financial Market Returns and Long-Term Investment Strategies" by Jeremy J. Siegel. However, as information regarding such potential anomalies disseminates throughout the market, these effects typically diminish. As illustrated in the chart below, spanning from 2000 to 2019, January prices rose on ten occasions but also decreased on ten occasions.

Optimal month for selling stocks

September is commonly regarded as a month of decline. The September effect underscores historically poor returns during this ninth month of the year, possibly influenced by institutional investors concluding their third-quarter positions. Indeed, as depicted in the aforementioned chart of monthly average returns, September typically records the lowest averages in the calendar year. Consequently, some traders advocate selling stocks in September.

Additionally, the October effect holds significance for certain investors. Despite October historically being a positive month on average, numerous major market crashes, including the Panic of 1907, the Great Depression, and Black Monday, have occurred during this month. Therefore, while September may exhibit weaker performance on average compared to October, selling stocks in September might be preferable to avoid the heightened volatility often associated with October.

Optimal day of the month

While there isn't a single day every month universally ideal for buying or selling, there's a tendency for stocks to increase at the start of a month. This pattern is primarily due to periodic inflows of new money allocated to mutual funds at the beginning of each month.

Furthermore, fund managers often aim to enhance their balance sheets by purchasing stocks that have performed well during the quarter's closing days. Consequently, stock prices tend to decline in the middle of the month.

Hence, traders might find it advantageous to time stock purchases near the month's midpoint, typically around the 10th to the 15th. Conversely, the optimal time to sell stocks would likely be within the five days surrounding the start of a new month.

Are there optimal times for buying or selling stocks?

Historically, certain days or months have exhibited better or worse performance for stocks, challenging the theories of efficient markets. These market anomalies, once prevalent, have largely vanished as they became widely recognized and trading became increasingly automated.

Benefits of dollar-cost averaging for investors

Dollar-cost averaging involves purchasing a fixed amount of a particular stock at regular intervals. For instance, one might buy five shares of stock ABC every two months, irrespective of the price. This strategy aims to mitigate price fluctuations and potentially lower the average price paid per share. Additionally, it eliminates the need to time the market.
