NEW YORK (TheStreet) -- Shares of PACCAR (PCAR - Get Report) are climbing 4.73% to $58.70 on heavy trading volume on Tuesday afternoon after posting better-than-expected earnings for the 2016 first quarter.

Separately, TheStreet Ratings Team has a "Buy" rating with a score of B+ on the stock.

The company's strengths can be seen in multiple areas, such as its notable return on equity, attractive valuation levels, good cash flow from operations and largely solid financial position with reasonable debt levels by most measures.

The team believes its strengths outweigh the fact that the company has had lackluster performance in the stock itself.

Recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
