The S&P/ASX 200 Index (ASX: XJO) is having a fairly flat day of trading as it stands this Tuesday afternoon. At the time of writing, the ASX 200 is sitting at 7,444 points, up a paltry 0.04% so far today.
That's despite a strong opening this morning, which took the ASX 200 up to 7,471 points just after trading began. So rather than dwelling on what could have been, let's instead check out the ASX 200 shares topping the trading volume charts so far today, according to investing.com.

3 most active ASX 200 shares by volume on Tuesday
Aurizon Holdings Ltd (ASX: AZJ)
Rail freight company Aurizon is our first ASX 200 share to check out today. Aurizon has, so far this Tuesday, seen a hefty 17.56 million of its shares trade hands.
There is no major news or announcements out of this company today. However, as we noted yesterday, Aurizon has shot to the top of the most traded shares pile this week, probably as a result of the $2.35 billion deal to acquire One Rail Australia that was announced last week. Today has seen the Aurizon share price lose 1.7% of its value so far today to trade at $3.46 at the time of writing.
Sydney Airport (ASX: SYD)
Sydney Airport is our second ASX 200 share today. A sizeable 17.75 million shares of this airport operator have been bought and sold so far. That's also despite the absence of any news out of this company today.
However, the Sydney Airport share price has taken a hit today and is currently down by 1.57% to $8.17 a share. This drop is probably behind this elevated trading volume.
Pilbara Minerals Ltd (ASX: PLS)
Our third and final ASX 200 share today is Pilbara Minerals. This ASX lithium producer has seen a whopping 22.63 million of its shares change owners thus far this Tuesday. This seems to be a consequence of the new joint venture the company announced this morning.
As my Fool colleague James covered earlier, Pilbara has signed an agreement with the Korean company POSCO to develop a conversion facility in South Korea. The Pilbara share price has responded very enthusiastically to this news, up 6.7% at the time of writing to $2.23. This news and share price move are almost certainly behind the large trading volumes we are seeing today.
