The S&P/ASX 200 Index (ASX: XJO) finished the day up 0.59% to 7,308.6 points at the closing bell.
Let's look at the biggest movers and shakers among ASX 200 shares today, based on trading volumes.
The ASX 200 shares that saw the most trading today
Alumina Limited (ASX: AWC)
Alumina was the most heavily traded ASX 200 share on the boards today, with a very heavy 19.96 million shares finding their way around the market.
This aluminium/alumina producer saw a fair level of volatility during today's session.
Alumina shares opened strongly and were up more than 1.2% at one point. But by close of trade, the company had given up all of those gains to finish at $1.63 — the same closing price as yesterday.
Telstra Corporation Ltd (ASX: TLS)
Telstra was another top volume ASX 200 share today. A substantial 19.25 million shares traded hands but the price only moved 0.8% up to $3.79.
This ASX 200 share has had a heck of a week. Telstra shares rocketed 4.6% on Wednesday to hit a new 52-week high and remain up 5.42% over the past 5 trading days.
Telstra's Wednesday announcement that it will be selling off half of its mobile towers business seemed to be the underlying catalyst here.
A2 Milk Company Ltd (ASX: A2M)
The A2 Milk share price had a fantastic day, gaining a robust 5.16% to finish the session at $6.52. This is probably why 12.46 million shares were traded.
As my Fool colleague covered this morning, A2 has been the recipient of some broker love recently, which might have contributed to this large trading volume, too.
The A2 Milk share price is still down 43% year to date, but it's also up more than 27% since its most recent low on 19 May.
A non-ASX 200 honourable mention
Although 88 Energy Ltd (ASX: 88E) is not an ASX 200 share, it is still worth mentioning today. Why? Well, because a mind-boggling 597.7 million 88 Energy shares were traded today.
This probably contributed to the 88 Energy share price shooting up by close to 40%, which I invite you to read all about!
