There were only two instances of declines for the rest of the year, in 1987 (-13%) and 1986 (-0.1%)." With the rebound of the stock market, the old adage "Sell in May and Go Away" seems to have been a bad advice once again. Last month, the S&P 500 index rose 4.8%, the best May performance since 2009. The NASDAQ 100 index rose nearly 6.2%, and the NASDAQ Composite Index rose 6.9%. Goldman Sachs FICC & Equities Trading Division said: "History doesn't really support this saying. Don't sell, leave the market (go on vacation), and enjoy the good times." The rising trend is still to be continued? If history is any guide, it may indicate that the rise of the stock market is not over yet. Looking ahead to the rest of 2024, Scott Rubner, Managing Director of the Goldman Sachs Global Markets Division and tactical expert, pointed out the following historical background for investors. Rubner stated that the S&P 500 index has risen 10.7% year-to-date, and since 1950, the S&P 500 index has risen more than 10% 21 times as of the end of May. In about 90% of these cases, the S&P 500 index rose for the rest of the year. There were only two instances of declines for the rest of the year, in 1987 (-13%) and 1986 (-0.1%). "Since 1950, the median return of the last 7 months of each year (June 1 to December 31) is 5.4%. In the aforementioned 21 cases, the average performance of the last 7 months increased to 8.1%." Rubner added. Rubner also pointed out that the NASDAQ index has risen for 16 consecutive Julys, with an average return of about 4.64%.

The Centers for Disease Control and Prevention (CDC) in the United States reported an outbreak related to mcdonald's (MCD.US) McDonald's 'Quarter Pounder' burger, which has resulted in 49 illnesses, including 10 hospitalizations and 1 death. The affected states include Colorado, Nebraska, and ten other states, with most cases concentrated in Colorado and Nebraska. The CDC noted that most patients reported consuming McDonald's 'Quarter Pounder' burgers before experiencing symptoms, with one patient developing hemolytic uremic syndrome that can lead to kidney failure. Following this news, McDonald's stock price fell nearly 10% in after-hours trading.

McDonald's quickly responded to this incident, stating that they are taking 'prompt and decisive action,' and preliminary investigation results suggest a possible link to sliced onions from a single supplier used in making the 'Quarter Pounder' burger.

McDonald's has instructed all local restaurants to remove sliced onions from their supply and temporarily halt distribution of this ingredient in affected areas. Additionally, McDonald's has temporarily stopped selling the 'Quarter Pounder' burger in some areas of western states like Colorado, Kansas, Utah, Wyoming, as well as other regions, collaborating with suppliers to replenish ingredients.

This food safety incident has impacted McDonald's stock price, which initially dropped nearly 10% after the announcement, now down 5%. Meanwhile, the stock prices of competitors have seen an increase, such as the parent company of Burger King.$Restaurant Brands International (QSR.US)$and$The Wendy's Co (WEN.US)$And$Shake Shack (SHAK.US)$.

Joe Erlinger, President of McDonald's USA, emphasized in a video that most states and menu items have not been affected by this outbreak. He pointed out that the company's other beef products, including cheeseburgers, hamburger, Big Macs, Double McDonald's, and Double Cheeseburgers, remain unaffected as they use different types of onion products.

As a globally renowned fast-food chain, McDonald's has always prioritized food safety. The company has taken a series of measures to ensure food safety, including providing food safety training to employees, establishing a Food Safety Digital System (DFS), and collaborating with suppliers to offer food safety training.

Nevertheless, this incident once again reminds the dining industry of the importance of food safety, and the need to take rapid and transparent measures when faced with potential food safety issues. Joe Erlinger, the President of McDonald's USA, emphasized the company's commitment to food safety in a video, and expressed the hope of quickly restoring full menus in the affected states.
