The Sayona Mining Ltd (ASX: SYA) share price is continuing to race to incredible highs today.
At market open, the emerging lithium producer's shares leapt to an intraday high of 35.5 cents.
However, some profit taking has led the share to slightly retrace to 35.3 cents apiece, up 8.46%.
Nonetheless, this makes it one of the top gainers on the ASX today, behind shares in lithium peer, Global Lithium Resources Ltd (ASX: GL1).
Sayona shares accelerate
Despite the company not releasing any announcements to the market lately, investors are buying up the Sayona share price.
This comes as the S&P/ASX 200 Materials (ASX: XMJ) sector is outperforming the broader ASX to surge 2.22% today.
That makes it the hottest index at the moment, and investors aren't letting up on it.
In the past week alone, the materials sector is up 7.46%.
Another factor that is likely providing support is the upcoming quarterly rebalance of the S&P/ASX Indices.
Sayona is set to be added to the S&P/ASX 200 Index (ASX: XJO) on Monday 19 September.
In turn, this enables fund managers to buy Sayona shares
Most fund managers are required to buy or sell shares within specific indexes such as the ASX 200.
With this in mind, investors usually like to take pre-emptive action in buying these shares before being accessible to fund managers.
