In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) is on course to record a disappointing decline. At the time of writing, the benchmark index is down 0.9% to 7,058.2 points.
Four ASX shares that are not letting that hold them back are listed below. Here's why they are rising:
DroneShield Ltd (ASX: DRO)
The DroneShield share price is up over 3% to 32.5 cents. This morning, the counterdrone company released a presentation ahead of its appearance at the Canaccord Genuity Defence Conference Presentation. This appears to have gone down well with some investors that were in attendance.
Origin Energy Ltd (ASX: ORG)
The Origin Energy share price is up 3% to $8.08. After initially opening lower, this energy giant's shares are now rising despite the collapse of its takeover. Some investors could be betting on an improved offer being made. Alternatively, they may believe that there could be a good long-term investment opportunity here based on the takeover interest.
ResMed Inc. (ASX: RMD)
The ResMed share price is up 1.5% to $24.66. This follows a solid session for the sleep treatment company's shares on Wall Street overnight. In addition, it is worth noting that the healthcare sector is one of the only sectors rising on Tuesday.
Whispir Ltd (ASX: WSP)
The Whispir share price is up 10% to 54 cents. This morning, this cloud communications company revealed that it has received a letter of intent from Zipline Cloud setting out its intention to submit a non-binding indicative proposal to acquire it. The indicative offer will be at a premium to the current offer on the table from Soprano of $0.48 per share.
