The S&P/ASX 200 Index (ASX: XJO) is once again climbing during this Wednesday's session in what is turning out to be a top week thus far for ASX shares. At the time of writing, the ASX 200 has gained a bouncy 0.14%, putting the index just below 6,990 points. That puts the ASX 200 up over 3% this week so far alone.
But let's delve deeper into these gains today by taking a look at the ASX 200 shares that are presently at the top of the share market's trading volume charts, according to investing.com.
The 3 most traded ASX 200 shares by volume this Wednesday
Medibank Private Ltd (ASX: MPL)
First up today is the ASX 200 private health insurer Medibank Private, with a notable 14.9 million shares traded thus far. There haven't been any fresh developments out of the company itself today. However, Medibank has been going through a lot in recent weeks, thanks to a well-publicised cyberattack.
After its shares returned from a trading halt last month, the company was battered. However, investors seem to be in a forgiving mood today, giving Medibank a 1.6% gain to $2.90 a share. It could be this that has lured so many shares to a new home with this healthcare share today.
Pilbara Minerals Ltd (ASX: PLS)
ASX 200 lithium share Pilbara Minerals is next up today. This Wednesday has seen a hefty 17.7 million Pilbara shares bought and sold so far. There's been no news out of this company today.
However, that hasn't stopped the Pilbara share price from defying the broader markets and recording a depressing fall. Currently, Pilbara shares are down a nasty 3.4% at $5.13. It's this steep drop that is probably causing the high volumes we are seeing.
Lake Resources N.L. (ASX: LKE)
Our final share this Wednesday is another ASX 200 lithium stock in Lake Resources. This session has had a sizeable 31.13 million Lake shares exchanged thus far. Despite sharing a common purpose, Lake shares are going the opposite way to those of Pilbara today.
At present, Lake Resources is up a pleasing 5.66% at $1.12 per share. As my Fool colleague Brooke covered earlier, this appears to be a result of the company's promising update regarding its Kachi Project.
