Just caught that Enpro (NPO) crushed earnings expectations - posted $1.99 per share versus the consensus estimate of $1.91. That's a solid beat, especially considering they hit $1.57 a year ago. The company also topped revenue estimates, bringing in $295.4 million against expectations of around $280 million. Pretty consistent track record too - NPO has beaten EPS estimates three times in the last four quarters.

What caught my eye is that NPO shares are up about 25.8% since the start of the year while the S&P 500 has basically flatlined. That's solid outperformance, but the real question is whether they can keep it going. Management's going to have to deliver some convincing guidance on the earnings call because the stock's momentum is going to depend a lot on what they say about the next few quarters.

Looking ahead, consensus expectations for NPO are $2.08 per share next quarter on roughly $305 million in revenue. For the full year they're expecting $8.77 per share. The Zacks rating currently sits at a Hold (Rank #3), which basically means the market expects NPO to move in line with the broader market for now. Worth keeping on the watchlist, but nothing screaming buy or sell at this moment. The tech services sector itself is in the bottom half of performance rankings, so that's another factor to consider.
