I’m now shorting the stock I’m longing it

If you're shorting ResMed, it's important to consider the following:

1. Short Selling Risks: Short selling involves borrowing shares and selling them with the intention of buying them back at a lower price. However, there is no upper limit to the amount you'd have to pay to replace the borrowed shares, and the price of the stock can continue to rise.
2. Company Performance: ResMed has reported strong financial results, and the company's strategic expansions and focus on innovation could support the stock price. If the company continues to perform well, the price of the stock may not decrease as expected, which could result in losses for the short seller.
3. Market Conditions: The sleep and respiratory health devices market is recovering, and ResMed is well-positioned to benefit from this trend. Positive market conditions could lead to an increase in the stock price, rather than a decrease.
4. Short Covering Costs: When short covering, you'll need to buy back the shares at the current market price, which could be higher than the price at which you sold them. This means you'll need to pay any difference between the entry and exit prices, including interest and commission fees.
5. Risk Management: Consider your risk tolerance and the potential for the stock to move against you. Short selling involves significant risk, and it's important to have a clear plan in place for managing your position.

In conclusion, shorting ResMed could be a risky strategy, given the company's strong financial performance and market conditions. If you're considering shorting the stock, carefully weigh the risks and potential losses, and ensure you have a clear risk management plan in place.
