With the new financial year off and running, now may be a good time to think about shaking up the S&P/ASX 200 Index (ASX: XJO) stocks in your portfolio.
That's because the top performers of the past year may not be able to match that pace in the year ahead. Or they could even stumble and get sold off amid sky-high market expectations.
On the flip side, some ASX 200 stocks that have underperformed over the past months could be set for a year of outperformance ahead.
Below we look at three such companies, with brokers tipping two as sells and one as a buy (courtesy of The Bull).
Two ASX 200 stocks to sell
Starting with the sell side, Seneca Financial Solutions' Arthur Garipoli recommends taking profits on two companies that have seen their share prices surge this year.
First up is tech company Megaport Ltd (ASX: MP1).
"Megaport provides network-as-a-service solutions, enabling businesses to connect seamlessly with cloud service providers," said Garipoli, who has a sell recommendation on the ASX 200 stock.
"The shares have risen from $8.66 on April 7 to trade at $15.12 on August 14," he noted.
At time of writing Megaport shares are trading for $14.91 apiece. That's up a whopping 101% in 2025.
Addressing his sell recommendation, Garipoli said:
The company has guided to increasing revenue in fiscal year 2026 due to new products and greater market penetration via an increasing sales team. However, in our view, it appears such a positive outlook has been priced into the stock.
Any delays or issues to fiscal year 2027 sales plans is likely to be punished by the market. We suggest investors consider taking profits while the share price exhibits strength.
Which brings us to the second ASX 200 stock he recommends selling, Eagers Automotive Ltd (ASX: APE).
"Eagers is an automotive retail group operating in Australia and New Zealand," Garipoli said.
He added:
New vehicle sales in Australia in July 2025 were up 2% on the prior corresponding period. APE's performance has been strong due to demand for electric vehicles. The company is well managed.
But with Eager's shares up 81.8% in 2025 (and up 106% since this time last year), Garipoli said the stock is looking expensive.
He noted:
The company's price/earnings ratio is trading well above its long-term average, so investors may want to consider locking in some gains. The shares have risen from $16.77 on June 20 to trade at $21.24 on August 14.
Which brings us to…
One promising ASX share to buy
As for which ASX 200 stock you may wish to add to your holdings, Baker Young's Toby Grimm is tipping global pathology provider Sonic Healthcare Ltd (ASX: SHL).
Sonic Healthcare shares are up 5.2% in 2025.
"Australia's leading pathology services provider continues to trade at a steep discount to our valuation despite supportive Medicare data and ongoing efforts to manage costs," said Young, who has a buy recommendation on Sonic Healthcare.
According to Young:
While uncertainty regarding Sonic's US business persists in terms of scale and growth, we're looking for an encouraging update when the firm delivers financial results on August 21.
SHL generated statutory revenue of $4.669 billion in the first half of fiscal year 2025, an increase of 8.4% on the prior corresponding period. EBITDA of $827 million was up 12.3%.
The ASX 200 stock is scheduled to release its results tomorrow.
