Mustang Bio, Inc. Stock Growth Grade

The foundation of growth investing is seeking out stocks of companies exhibiting strong, consistent and prolonged growth that is expected to continue into the future.

In order to compute the Growth Score and assign it a letter grade, the percentile ranks for each of the three individual components‐consistency of annual sales growth, five‐year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations‐must be determined. These three rank figures are added together, and the sum is ranked against the entire stock universe to arrive at a company’s Growth Score to create an equal distribution of grades.

The companies in the bottom 20% of the stock universe receive Growth Grades of F, considered Very Weak, while those in the top 20% receive A grades, which are considered Very Strong.

Mustang Bio, Inc. Stock Momentum Grade

Momentum grades help 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. Momentum is based on the price change of a stock over a specified period relative to all other stocks.

Typically, AAII looks at the weighted relative strength over the trailing four quarters. The weighted four-quarter relative strength rank is the relative price change for each of the past four quarters. The most recent quarterly price change is given a weight of 40% and each of the three previous quarters are given a weighting of 20%.

Mustang Bio, Inc. has a Momentum Score of 6, which is Very Weak.

Other Mustang Bio, Inc. Stock Grades

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

The Earnings Estimate Revisions Grade takes into account the magnitude of a company’s earnings surprise in its last two reported fiscal quarters. Often, surprises beget further surprises‐or at least continued sales growth (the exact opposite is generally true, too). AAII’s stock screen that follows the companies with the highest earnings estimate revisions (i.e., the best grades) has a 23.3% backtested annual return since inception, whereas an example screen following those with the worst revisions has a backtested annual return since inception of under 5%.

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