Saia shares lag S&P 500 as volume growth slows

Saia's stock has fallen to $334.81 over the past six months, a 17.2% loss that contrasts sharply with the S&P 500's 12% gain during the same period. Analysts from StockStory express caution regarding the ground transportation company, citing concerns about volume growth, earnings efficiency, and declining returns on capital. These factors lead the firm to recommend avoiding the stock in favor of a dominant aerospace business with a strong acquisition strategy.

Volume is cited as the critical metric for ground transportation firms, as customer willingness to pay for price increases has limits. Saia's tons shipped reached 1.71 million in the latest quarter. Over the last two years, this figure averaged 2.6% year-on-year growth, a pace described as underwhelming. The analysis suggests that to accelerate growth, the company may need to lower prices or invest in product improvements, both of which could hinder near-term profitability.

The long-term trajectory of earnings per share (EPS) indicates that Saia's incremental sales have not been equally profitable. Over the last five years, EPS grew at a compounded annual rate of 7.9%, which is lower than the company's 11% annualized revenue growth over the same period. This divergence implies that the company became less profitable on a per-share basis as it expanded its revenue base.

Return on invested capital (ROIC), a measure of operating profit relative to raised capital, has decreased significantly over recent years. While management's past actions are viewed positively, the declining returns are interpreted as a symptom of fewer profitable growth opportunities available to the firm.

Following the recent drawdown, Saia trades at a forward P/E of 26.2 times, based on its share price of $334.81. Despite the lower entry price, the analysis concludes that the potential upside is not attractive relative to other available investments. The report identifies a dominant aerospace business that has perfected its M&A strategy as a preferred alternative.
