Investors should take note of that fact in the wake of the bank's record fourth-quarter earnings, which raised near-term profit questions.
Generally, today's earnings show why Wells Fargo remains a best-in-class bank that has earned Buffett's long term investing imprimatur. All three of Wells Fargo's businesses -- community banking, wholesale banking, and wealth management -- grew profits from quarter-ago and year-ago levels.
Those looking for a short-term trade, however, might have been disappointed. Expect Wells Fargo's fundamental growth to be at the head of the banking sector in 2013, even if near-term earnings issues prove a concern to some.
Wells Fargo reported better than expected revenue of $21.9 billion and profitability of $5.1 billion, signaling that the bank's steady share performance remains on track heading into 2013.
Meanwhile, the bank's 20% 2012 earnings per share growth reflected impressive growth and a strengthening position to the recovering US housing market. Wells Fargo is also increasingly returning capital to investors, boosting buybacks by a total of 48 million shares.
Still, worse-than-expected interest-based earnings continue to cloud Wells Fargo's short-term share performance in the New Year.
Wells Fargo reported its net interest margin -- the difference between what it earns on loans and what it pays to fund them -- fell a greater-than-expected 10 basis points while expenses also increased. On the positive side, core loans grew $47.7 billion and the bank's improving loan quality drove a $250 million reserve release.
Marty Mosby, a large-cap banking analyst with Guggenheim Partners, said in an interview prior to earnings that any reported net interest margin decline of less than 5 basis points and loan growth sequentially from the third quarter would be taken positively by investors.
Wells Fargo impressed on one of those fronts, while a greater than expected NIM decline meant overall interest-earnings for the bank fell $249 million to $10.6 billion.
The earnings give a crucial insight for investors into the term trends driving Wells Fargo's profitability and growth given the bank's top footing in the housing market, healthy balance sheet and industry leading dividend payout.
Investors and banking sector analysts are watching interest margins and loan growth as a key proxy for the impact of a third round of Federal Reserve easing announced in September and insight into the strength of the housing market.
A stabilization of Wells Fargo's interest margins after a 25 basis point drop in the third quarter would have removed the bank's biggest near-term earnings risk, freeing investors to focus on longer-term trends, according to Mosby.
"The market right now is discounting Wells Fargo's earnings power because they think it is going to be lost because of significant compression of net interest margin," said Mosby.
Investors may need to wait another quarter for interest margins to bottom, and for Wells Fargo's strong fundamental qualities to overshadow short-term headwinds.
Mosby argues that if uncertainties such as interest-earnings and the sustainability of loan demand dissipate, Wells Fargo could outperform the banking sector in 2013 as it has in years past. The analyst notes that while Wells Fargo has doubled earnings since the financial crisis, investors have given the bank little credit.
Wells Fargo shares currently stand roughly in-line with pre-crisis levels seen in 2007.
Bill Smead, the chief investment officer of Smead Capital Management, expects Wells Fargo's exposure to a housing pickup to more than offset and Fed interest rate policies. "We happen to think a company like Wells Fargo might make more money in the rebound on the value in foreclosed homes than what they will lose on a decline in their interest rate spreads," said Smead, in an interview prior to earnings.
"That will wash out in the long run, which is why you want to increase market share," said Smead of Wells Fargo's increasing presence in the mortgage market and its deposit growth.
Wells Fargo's deposits grew to $928 billion in the fourth quarter, a 7% increase from year-ago levels. Those deposits, however, cut at Wells Fargo's net interest margin by 5 basis points, according to the bank. In a rising rate environment, Smead that margin pressure to reverse.
Smead, who also owns JPMorgan and Bank of America shares, said Wells Fargo's risk reward relationship compares favorably to large cap banking peers in a normal economy.
In addition to a careful eye on interest margins and loan growth, Stifel Nicolaus analyst Christopher Mutascio said the bank's efficiency ratio and reserve releases are an important investor concern. Recently, Wells Fargo abandoned an expense target of $11.25 billion for a ratio of between 55% to 59% of overall revenue as a result of surging housing market and refinancing activity.
Mutascio expected that after reserve releases fell through 2012, the quarterly releases could stabilize at between $150 million and $200 million through 2013 and 2014.
While Wells Fargo released $250 million in reserves, it showed a decline in its efficiency ratio, which rose to 58.8%, at the high end of the bank's guidance, due to a charitable contribution.
Given Wells Fargo's above industry average stock and earnings performance in recent years, some Wall Street analysts recently saw reason to downgrade their outlook for the bank, citing value at competitors Bank of America and Citigroup.
Betsy Graseck, a banking analyst with Morgan Stanley (NYSE:MS) downgraded Wells Fargo from 'Outperform' in late December, citing " less ability to improve
Such near-term earnings and valuation concerns relative to lenders like Bank of America and Citigroup, who remain far below pre-crisis levels, aren't likely to phase Wells Fargo's largest investor Warren Buffett.
"Nine years from now I would think that Bank of America as well as Wells Fargo
That perspective might serve Wells Fargo and banking sector investors, in the wake of Friday's earnings.
In the fourth quarter, Wells Fargo recorded took a $644 million charge for a Monday foreclosure settlement agreed with the Federal Reserve and Office of Comptroller of Currency (OCC), which has the bank committing a total cash payment of $766 million and a further $1.2 billion for already provisioned for foreclosure prevention.
