End-of-day summary:
The share market's biggest float in three years provided much of the excitement during a flat session for the wider market.
Mexican fast food chain Guzman Y Guzman finished its first day on the boards with a 36.36% gain, valuing the company at more than $3 billion.
That explosive rise was the highlight of an otherwise low-key session as a midweek US market holiday robbed the rest of the market of trade flow. The ASX 200 finished more or less unchanged, down a third of a point as healthcare providers, tech companies and supermarkets declined. Gold miners were among the day's best performers, alongside small caps, REITs and banks.
With Wall Street closed for the Juneteenth holiday, traders took their cues from Europe, where the Stoxx 600 dipped 0.17%.
