Is Stock Trading Also Dependent on the Date? Selling Stocks on Monday Leads to the Biggest Loss

Interesting research data: Investing $10,000 in the S&P 500 in 2005 and holding it until 2024 would grow to $71,750, with an annualized return of 10.4%. But what if you traded frequently? Missing the best 60 trading days would reduce your account to $4,712, a loss of 3.7%.

**The question is**—when should you trade?

Market research has uncovered an interesting pattern:

**Worst Time: Monday**
- Known as the "Monday Curse," stocks tend to open with gaps downward
- Why? Weekend news accumulates, and investors tend to sell off at the market open on Monday, increasing selling pressure

**Best Times: Tuesday to Thursday**
- Tuesday is the optimal buying day, as investors have digested weekend news and are more stable emotionally
- Selling before market close on Friday is also good, since the day's price fluctuations are already absorbed

**But there's a catch**: Frequent day trading based on the calendar can lead to overtrading and greater losses. The real factors influencing stock prices are company fundamentals, interest rate policies, and economic data—not the day of the week.

Long-term investors can completely ignore this pattern; holding steady is the key to making money.
