Bank stocks have been on fire since the election. Wells Fargo (WFC), one of the biggest banks in the U.S., is up 18% since November 8th. There has been a remarkable shift in investor sentiment in just the past six months.

For most of 2016, Wells Fargo investors faced the unfolding fake accounts scandal, tightening regulations, and weak growth stemming from low interest rates. But in the aftermath of the election, things are looking up for Wells Fargo shareholders.

One of the company’s biggest investors is Warren Buffett, Chairman and CEO of Berkshire Hathaway (BRK-A) (BRK-B). Berkshire owns 479.7 million shares of Wells Fargo, worth approximately $26.70 billion. (To see the complete list of all 47 stocks in Warren Buffett’s portfolio, click here.)

Investor hopes are buoyed by the prospect of a much friendlier regulatory environment, and a compelling growth catalyst in the form of rising interest rates. This article will discuss why Wells Fargo is a classic Buffett stock, with a positive outlook going forward.

Business Overview

Wells Fargo is the nation’s third-largest U.S. bank by assets. It was founded all the way back in 1852. This is a more difficult period for Wells Fargo than usual, due to the company’s fake accounts scandal. Wells Fargo incurred a $185 million fine, because it opened millions of accounts for its customers without their consent.

It eventually cost the CEO his job, and cast a cloud of uncertainty over the company for most of 2016. While Wells Fargo’s full-year revenue increased 2.6%, its earnings-per-share declined 3.2%, to $3.99. The results deteriorated as the year progressed. Earnings-per-share declined 7% in the fourth quarter.

The good news is, Wells Fargo’s financial performance held up well. The company remained highly profitable in 2016, which is a testament to its competitive advantages. This allowed the company to continue investing in the business and buying back stock, which helped keep earnings afloat.

Conditions have remained stable to start 2017. Revenue dipped 0.9% in the first quarter, but earnings-per-share rose 1% thanks to cost cuts and share repurchases. The company benefited from growth in average loans and deposits, which increased 3.9% and 6.5%, respectively, year over year.

Going forward, Wells Fargo has plenty of promising growth catalysts.

Growth Prospects

Wells Fargo has several growth catalysts to look forward to. First and foremost, it should benefit from higher interest rates. On March 15, the Federal Reserve raised interest rates for the third time since the financial crisis ended. The central bank is expected to raise rates a total of three times in 2017.

This will be a major boost to Wells Fargo. As the largest mortgage originator in the U.S., higher interest rates will increase its net interest margin, which is the spread between interest earned on loans versus interest paid on deposits. In addition, the company is undergoing a major cost-cutting program. It expects to cut expenses by $2 billion annually by year-end 2018.

Management is targeting several areas of the business for cost reduction, including compensation, marketing, third-party expenses, infrastructure, travel, and more. Another growth catalyst is an improving loan portfolio. Wells Fargo’s allowance for credit losses as a percentage of total loans was 1.28% last quarter, down from 1.34% in the same quarter last year.

Lastly, Wells Fargo’s bottom line could benefit from a more favorable regulatory climate. The Trump administration has expressed a desire to cut financial regulations, such as Dodd-Frank, in an effort to spur economic growth.

Valuation & Expected Returns

Despite Wells Fargo’s impressive rally over the past 6+ months, the stock is still cheap. Wells Fargo trades for a price-to-earnings ratio of 13.3, based on trailing earnings-per-share over the past year. It is much cheaper than the S&P 500 Index, which has an average price-to-earnings ratio of 26. As a result, Wells Fargo shares appear to be undervalued. An expanding price-to-earnings ratio would yield a significant return.

Investors could become more comfortable with Wells Fargo’s position, given the company’s long track record of steady profitability.

Wells Fargo remains a high-quality business, which could warrant a higher valuation multiple, once the negative news fades into memory. For example, if Wells Fargo’s price-to-earnings ratio expands to 15, it would represent a return of approximately 13%. Plus, Wells Fargo is likely to grow earnings-per-share moving forward, given its many growth catalysts.

Wells Fargo’s future returns will be based on earnings growth and dividends. A potential breakdown of future returns is as follows:

• 4%-6% earnings growth
• 2.8% dividend yield

The company could reach mid-single digit earnings growth, based on a combination of revenue growth, cost cuts, and share repurchases. Including the 2.8% dividend yield, total annualized returns could reach a range of approximately 7%-9% per year.

Dividend Analysis

Not only is Wells Fargo stock potentially undervalued, it is also an attractive stock for income. Even though the current environment is challenging, Wells Fargo’s capital levels are strong, which enable its shareholder capital returns.

Wells Fargo currently pays a dividend of $1.52 per share, which yields 2.8% based on its share price. This is a higher dividend yield than the market average. The S&P 500 Index has an average yield of just 2%. As a result, Wells Fargo stock provides 40% more income than the average stock in the S&P 500.

And, there could be potential for Wells Fargo to raise its dividend down the line. To be sure, there is a good chance the company will keep its dividend steady for 2017, as it works to recover from the fake accounts scandal. But, thanks to the company’s highly profitable business model and multiple growth catalysts, Wells Fargo could return to dividend growth in 2018 and beyond.

Based on Wells Fargo’s 2016 earnings-per-share, the stock has a payout ratio of just 38%. This is a fairly modest payout ratio, which leaves room for dividend increases going forward.

Final Thoughts

Warren Buffett famously looks for companies that he can buy and hold over the long term. There is perhaps no company in the financial sector that epitomizes this more than Wells Fargo. Throughout Wells Fargo’s 165 year history, it has navigated all sorts of challenging economic periods, including two World Wars, the Great Depression, and the 2008-2009 financial crisis.

Wells Fargo has come back from difficult situations before, and it will again. The company remains highly profitable with a firm growth outlook. And, the stock is cheap, with an attractive dividend yield.
