The S&P/ASX 300 Index (ASX: XKO) is flat today, despite some strong movers amongst the more popular companies.
At the time of writing, the ASX 300 is up 0.03% to 7,507 points.
It's worth noting that the index hit a record high of 7,519 points yesterday.
Let's take a look at which top ASX 300 shares are picking up steam during mid-afternoon trade.
Vulcan Energy Resources Ltd (ASX: VUL)
The first major mover in the ASX 300 is none other than Vulcan Energy. So far, this lithium company is continuing its positive run, surging 15.77% higher to $13.29. That means Vulcan Energy shares are now up 30% over the past week.
The company announced a 5-year partnership with major automobile manufacturer, Renault on Monday. In addition, Vulcan Energy also stated that its Zero Carbon Lithium project achieved a negative carbon footprint.
Z Energy Ltd (ASX: ZEL)
Another ASX 300 mover today is New Zealand-based fuel retailer, Z Energy, climbing 6% to $2.92. This comes despite the company not releasing any news today.
Z Energy's last price sensitive announcement came back in late May regarding an agreement to an in-principal deal with The New Zealand Refining Company on import terminal conversion.
It appears investors are buoyant on the ASX 300 company's share price, sending it 13% higher over the month.
Afterpay Ltd (ASX: APT)
Next up, the ASX 300 darling, Afterpay. The buy now, pay later (BNPL) giant is up 4.97% to $131.48.
Afterpay shares have been on the move this week following a takeover offer from Square Inc (NYSE: SQ) for $39 billion. As the United States payment company surged overnight, so too has Afterpay today.
Since 2 August, Afterpay shares have risen 14%, reflecting upbeat investor sentiment that the deal will go through. The Afterpay board unanimously voted in favour of the transaction.
