What on earth's going on with Zip shares?

Zip Co Ltd (ASX: ZIP) shares are giving investors another wild ride.

The ASX buy now, pay later (BNPL) stock dropped 5.5% to $2.23 at the start of the week. That pushed its one-month loss out to roughly 11% and its 2026 decline to around 32%.

And yet, somehow, Zip shares are still up about 8% over the past 12 months.

Confused? You are not alone.

Dramatic rollercoaster

The volatility has been relentless.

Back in April, Zip shares surged from $1.55 to $2.58 in just weeks. That marked a massive 66% rally as investors piled into the stock following a strong quarterly update.

But in May, sentiment turned sharply again. The ASX financial stock has since given back a large chunk of those gains and now trades roughly 54% below its 52-week high reached in October last year.

Zoom out further and the rollercoaster becomes even more dramatic. Zip shares are down around 68% over five years. But over 10 years, they are still up roughly 233%.

Seasick yet?

Consumer spending, risk sentiment

So what is actually driving all this volatility? Part of the answer comes down to sentiment.

Technology and growth shares have been under pressure again as investors reassess valuations and risk appetite. Higher interest rates, macro uncertainty, and concerns around consumer spending have all weighed on the sector.

Zip shares tend to amplify those swings because it sits right at the intersection of fintech, consumer spending, and risk sentiment.

When investors feel optimistic, Zip can soar. When markets turn defensive, the stock often gets hit hard.

April's rally was largely driven by improving operational momentum. The company's quarterly update showed continued progress on margins, profitability, and credit quality.

Investors responded positively to signs that Zip's turnaround strategy may finally be gaining traction.

What next for Zip shares?

Management has been focused on increasing revenue per customer while tightening lending standards and improving the quality of its loan book.

If successful, that strategy could turn Zip into a far more sustainable and profitable business over time.

But there are still plenty of risks.

Competition in the buy now, pay later sector remains fierce. Regulatory scrutiny also continues to hang over the industry, while changing consumer behaviour creates another layer of uncertainty.

Losing branding rights

And recently, Zip was hit by another setback after losing a court case linked to its branding rights in Australia.

The ruling means the company cannot use the "Zip" brand name locally in the way it had planned, adding another complication for investors already trying to assess the company's long-term outlook.

That combination of improving fundamentals and lingering uncertainty helps explain why the price of Zip shares keeps swinging so aggressively.

What do analysts think?

This remains a highly speculative ASX growth stock. The upside can be huge when momentum builds, but sentiment can also reverse very quickly.

Despite the recent sell-off, some analysts still see strong upside potential ahead. UBS remains bullish on Zip shares and recently reaffirmed its buy rating on Zip shares.

The broker has a 12-month price target of $3.10 on Zip shares. From current levels, that suggests potential upside of around 39%.
