Firefly Aerospace Inc. Stock Earnings Estimate Revisions Grade

The Earnings Estimate Revisions Score considers the magnitude of a company’s earnings surprise in its last two reported fiscal quarters. Often, positive surprises beget further positive surprises‐or at least continued sales growth (the exact opposite is generally true, too).

Estimate revisions offer an indication of what analysts are thinking about the short-term prospects of a firm. The Earnings Estimate Revisions Score is based on the statistical significance of a firm’s last two quarterly earnings surprises and the percentage change in its consensus estimate for the current fiscal year over the past month and past three months.

Firefly Aerospace Inc. has an Earnings Estimate Revisions Score of 20, which is Very Negative.

Other Firefly Aerospace Inc. Stock Grades

In addition to Estimate Revisions, A+ Investor also provides grades for Value, Growth, Momentum and Quality.

The Momentum Grade helps uncover stocks experiencing anomalously high rates of return; research finds that stocks with high relative levels of momentum tend to outperform, whereas those with low levels of momentum tend to continue underperforming.

Growth investing builds on the idea that stocks of companies exhibiting strong, consistent and prolonged growth outperform those of slower—growth companies. AAII measures several dimensions of growth in its Growth Grade, including year—over—year increases in sales and earnings, long(er)—term historical sales and earnings growth rates and analyst‐forecasted long—term earnings growth.

Successful stock investing involves buying low and selling high, so stock valuation is an important consideration for stock selection. Buying stocks that are going to go up typically means buying stocks that are undervalued in the first place, although momentum investors may argue that point.

AAII’s A+ Investor Quality Grade comes from the ranking of key metrics. Specifically, the Quality Grade is the percentile rank of the composite return on assets (ROA), return on invested capital (ROIC), gross profit relative to assets, buyback yield, change in total liabilities to assets, accruals, Z double prime bankruptcy risk (Z) score and F—Score.

These 4 key factors, when combined with the above, provide a holistic view into a stock. Further, by joining A+ Investor you can see whether Firefly Aerospace Inc.’s stock passes any of our 60+ stock screens that have outperformed the market since their creation.
