Alphabet is set to report earnings today after-the-bell; the first time since it's re-organization last August. Ahead of its results, the "Halftime Report" experts discussed whether the stock is a "buy" at current levels.

Pete Najarian is bullish the name. He thinks Google is likely to beat the street's estimates on the top and bottom line. There's plenty of room on the upside, he argues, although he will be watching for guidance on margins.

Jon Najarian agrees, arguing that YouTube will bolster Google's earnings report. Rather than view Facebook video as taking market share, he believes the focus on video across the sector will help Alphabet. Najarian is also watching for guidance on Google's next ventures--especially the SkyBender project.
