"We rate AXCELIS TECHNOLOGIES INC (ACLS) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including disappointing return on equity and poor profit margins."
