"The FTSE 250 mid-cap index keeps hitting record highs," said Michael Hewson, chief market analyst at London-based CMC Markets. "I would be looking for opportunities in France and Italy, simply because we are nowhere near the highs we saw in 2007."
The FTSE 250 has returned 13.3% since the start of the year, compared to the larger-cap FTSE 100's 9% gain.
Even though Germany is arguably the strongest economy in the eurozone, Hewson remains skeptical about finding value in German stocks.
"I would warn against the DAX," he said, referring to the Xetra DAX stock index that tracks 30 blue-chip German companies," he said, adding, "I think there is potential for a little bit of a reversal simply because of how far it has come higher over the last six to 12 months."
The DAX has risen almost 19% year-to-date.
Meanwhile, opportunity also exists in the United Kingdom.
"The UK 250 has outperformed the FTSE 100 pretty much consistently over the past three to four years, and it's still flirting with record highs," Hewson said. "The likelihood is that it will continue to push higher."
Within the U.K., Hewson is bullish on the telecom and utilities sectors.
