First Interstate BancSystem, Inc. and Banco Santander-Chile Stock Value Grades

Company	Ticker	Value
First Interstate BancSystem, Inc.	FIBK	B
Banco Santander-Chile	BSAC	na

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 Value Grade derives from a stock’s value score. The Value Score is the percentile rank of the average of the percentile ranks of the price-to-sales ratio, price-earnings ratio, enterprise-value-to-EBITDA (EV/EBITDA) ratio, shareholder yield, price-to-book-value ratio and price-to-free-cash-flow ratio. The score is variable, meaning it can consider all six ratios or, should any of the six ratios not be valid, the remaining ratios that are valid. To be assigned a Value Score, stocks must have a valid (non-null) ratio and corresponding ranking for at least two of the six valuation ratios.

Stocks with a Value Score from 81 to 100 are considered deep value, those with a score between 61 and 80 are a good value and so on.

First Interstate BancSystem, Inc. has a Value Score of 62, which is Value. Banco Santander-Chile does not have a meaningful Value Score.

The Value Stock Winner: Undetermined

If you are strictly a value investor, you may want to add First Interstate BancSystem, Inc. to your watch list. However, because only one of the companies in this comparison has a valid Value Grade, we cannot name it a clear winner. Evaluation of the other grades for both companies is necessary in order to understand which stock is the better investment based on AAII’s proprietary scores and analysis.

First Interstate BancSystem, Inc. and Banco Santander-Chile’s Quality Grades

Company	Ticker	Quality
First Interstate BancSystem, Inc.	FIBK	D
Banco Santander-Chile	BSAC	F

Like the Value Grade, AAII’s A+ Investor Quality Grade comes from the percentile rank of key metrics. Specifically, the Quality Score is the percentile rank of the average of the percentile ranks of 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 the F-Score.

The score is variable, meaning it can consider all eight measures or, should any of the eight measures not be valid, the remaining measures that are valid. To be assigned a Quality Score, stocks must have a valid (non-null) measure and corresponding ranking for at least four of the eight quality measures.

The Quality Score is used to assess the underlying “quality” of a particular stock. A higher-quality stock possesses traits associated with upside potential and reduced downside risk. Backtesting of the Quality Grade shows that stocks with higher grades, on average, outperformed stocks with lower grades over the period of 1998 through 2019.

Stocks receive better grades (higher scores) for having higher scores for the quality subcomponents and worse grades (lower scores) for lower scores for the subcomponents.

First Interstate BancSystem, Inc. has a Quality Score of 33, which is Weak. Banco Santander-Chile has a Quality Score of 7, which is Very Weak.

Company	Ticker	Earnings Estimate
First Interstate BancSystem, Inc.	FIBK	B
Banco Santander-Chile	BSAC	B

Earnings estimate revisions scores consider 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. Estimate revisions are 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.

First Interstate BancSystem, Inc. has a Earnings Estimate Score of 63, which is Positive. Banco Santander-Chile has a Earnings Estimate Score of 62, which is Positive.
