Some of the ASX 200's highest-quality shares have been hit hard over the past 12 months.
While this is disappointing, for investors with a long-term mindset, large falls in strong businesses can create buying opportunities.
This is especially true when the market becomes focused on short-term concerns while the company's long-term position remains attractive.
Here are three ASX 200 shares that are down heavily and could be bargain buys for patient investors.

Cochlear Ltd (ASX: COH)
Cochlear has been one of the biggest underperforming shares in the ASX 200 over the past 12 months.
Its shares are down approximately 62% over this period, leaving the hearing implant company well out of favour with investors.
That is a major move for a business with a long record of innovation, global leadership, and life-changing products.
Cochlear's devices help people with significant hearing loss reconnect with speech, sound, and daily communication. That gives the company a role that goes well beyond consumer electronics or discretionary healthcare.
The business operates in a specialised market where clinical trust, product reliability, surgeon relationships, and long-term patient support all matter.
Those advantages take years to build.
The recent share price weakness reflects disappointment over its recent performance. However, the long-term need for hearing solutions should continue to grow as populations age and access to treatment improves.
If Cochlear can restore confidence in its earnings trajectory, the selloff could prove to be a major opportunity for buy and hold investors.
REA Group Ltd (ASX: REA)
REA has also been sold down heavily.
Its shares are down approximately 40% over the past 12 months amid concerns about higher interest rates and proposed changes to negative gearing.
These issues have weighed on investor sentiment because REA is closely connected to the housing market. If property activity slows, listing volumes and advertising demand can come under pressure.
But the long-term investment case remains compelling.
REA owns realestate.com.au, one of Australia's most important property platforms. Buyers go there because the listings are there, agents list there because the audience is there, and vendors want access to the largest possible pool of potential buyers.
That loop gives REA a powerful position in the property ecosystem.
Housing markets move through cycles, and policy changes can affect confidence. But Australians remain deeply engaged with property, and digital marketplaces continue to play a central role in how homes are bought and sold.
A 40% fall may have created an opportunity to buy one of the ASX's best digital businesses at a far more attractive price.
Xero Ltd (ASX: XRO)
Xero has suffered the sharpest fall of the three ASX 200 shares.
The cloud accounting software company's shares are down approximately 65% over the past 12 months.
The broader tech selloff has hurt sentiment, and investors have also been weighing concerns about artificial intelligence disruption across software markets.
That has created a difficult backdrop for Xero.
However, the company remains deeply embedded in the financial workflows of small businesses, accountants, and bookkeepers.
Its platform helps users manage invoicing, payroll, bank feeds, reporting, compliance, payments, and adviser relationships. Once a business has built its financial processes around Xero, switching can become inconvenient and disruptive.
Artificial intelligence may also become a useful tool inside the platform over time, helping automate tasks and improve the value customers receive.
The share price fall shows how much expectations have reset. But if Xero keeps expanding internationally, adds more services, and uses technology to deepen its platform, the current weakness could prove to be an attractive entry point into one of the ASX's strongest software businesses.
