This article talks about how the price of crude oil went up by a little bit (over 1%) and some companies' shares became worth less money, while other companies' shares became worth more money. Crude oil is important because it helps make things like gasoline for cars and plastic for toys. Some of these changes happened because big companies bought small parts of other companies or because the companies had good or bad news about their plans. Read from source...

- The title is misleading and sensationalist, implying that crude oil rising over 1% is a significant event that would affect the markets. However, this is a very small percentage change that does not reflect the actual volatility or trend of the oil market. A more accurate title could be "Crude Oil Trades Slightly Higher; Some Stocks Rise and Fall".
- The article focuses too much on individual stocks and their short-term performance, rather than providing a broader perspective on the macroeconomic factors that drive the oil market. For example, it mentions BlackBerry's convertible senior notes offering, but does not explain why this would affect the price of crude oil or how it relates to the overall industry dynamics. A more informative article would provide a balanced view of the supply and demand factors, as well as the geopolitical risks that influence oil prices.
- The article uses vague and subjective terms such as "plunge" and "boost" to describe the stock movements, without providing any quantitative or comparative data. For example, it says that Evaxion Biotech's shares surged 116%, but does not compare this to its previous closing price or its market capitalization. A more objective article would use numerical indicators such as percentage changes, dollar amounts, and trading volumes to support its claims and show the relative significance of the stock movements.
- The article relies on secondary sources such as press releases, filings, and announcements to report the news, without verifying their accuracy or completeness. For example, it cites a 13G filing that shows Merck's stake in Evaxion Biotech, but does not check if this is a recent or relevant transaction, or if there are any conflicts of interest or hidden agendas behind the investment. A more responsible article would independently corroborate the information from primary sources such as interviews, statements, or reports, and disclose any potential biases or limitations in its coverage.

There are several factors that can influence the performance of an investment portfolio, such as economic indicators, company fundamentals, market sentiment, technical analysis, news events, etc. Based on these factors, I will provide you with some possible investment recommendations and their corresponding risks for each security mentioned in the article. Please note that these are not guaranteed to be profitable or accurate, and they are only meant to serve as a starting point for your own research and decision making. You should always do your own due diligence before investing in any security.

For BlackBerry:
- Investment recommendation: Buy at $2.9050 or lower with a stop-loss order of $2.60, aiming for a 10% gain. The rationale is that the company has a strong brand recognition and loyal customer base in the enterprise and government sectors, as well as a diversified revenue stream from software and services. Moreover, the proposed convertible senior notes offering could provide additional financing and flexibility for the company to pursue its strategic growth initiatives.
- Risk: The main risk is that the company may face increasing competition from other smartphone makers and cloud service providers, as well as regulatory challenges in some markets. Additionally, the convertible senior notes offering could dilute existing shareholders and increase interest costs for the company.

For Annovis Bio:
- Investment recommendation: Sell at $9.73 or higher with a take-profit order of $10.50, aiming for a 8% gain. The rationale is that the company has disappointed investors with its postponement in the Phase III study data release for buntanetap in Parkinson's Disease, which is a potential blockbuster drug for the treatment of cognitive impairment and depression associated with the condition. The delay could indicate that the clinical trial results are not as positive as expected, or that there are some technical issues with the data analysis. Furthermore, the company has a high short interest ratio of 35%, which suggests that many investors are betting against the stock.
- Risk: The main risk is that the company may never achieve regulatory approval for buntanetap, or that it may face tough competition from other drugs in the market. Additionally, the high short interest ratio could indicate that there is a possibility of a short squeeze, which could drive the stock price higher in the near term.

For DuPont:
- Investment recommendation: Sell at $65.94 or higher with a take-profit order of $70, aiming for a 6% gain. The rationale is that the company has
