Ally Financial

Ally Financial is a leading American bank holding company and a giant in the digital financial services landscape. To understand Ally, you have to know its past life as GMAC Inc. (General Motors Acceptance Corporation), the financing arm of General Motors. For decades, its job was simple: help people get loans to buy GM cars. However, the Great Financial Crisis of 2008 hit the company like a meteor, forcing it to take a massive government bailout. This near-death experience led to a radical transformation. Rebranded as Ally Bank in 2009, it shed its old skin and emerged as a diversified, digital-first bank. While it remains the largest auto lender in the U.S., its online bank has become a powerhouse, attracting billions in customer deposits by offering competitive interest rates. This dual-engine model—auto finance fueled by a low-cost online deposit base—is the key to understanding Ally's modern identity and its appeal to value investors.

A Value Investor's Perspective

From a value investing standpoint, Ally often presents a fascinating case study. It's a market leader that has frequently traded at a discount to its peers, partly due to the lingering memory of its GMAC past and its heavy exposure to the cyclical auto market.

Business Model Breakdown

Ally's business is a tale of two synergistic divisions. Understanding how they work together is crucial.

Key Ratios and Metrics to Watch

When analyzing Ally, value investors focus on a few key metrics to gauge its health and valuation.

  1. Price-to-Book (P/B) Ratio: Banks are often valued based on their book value (assets minus liabilities). A P/B ratio below 1.0 suggests the market values the company at less than its net worth, which can signal a potential bargain. Historically, Ally has often traded below a P/B of 1.0, reflecting market skepticism about its auto-centric business.
  2. Return on Equity (ROE): This measures how effectively management is using shareholders' capital to generate profits. An ROE consistently above 10-12% is generally considered strong for a bank. Comparing Ally's ROE to competitors like JPMorgan Chase or Wells Fargo provides valuable context.
  3. Credit Quality: This is the big one. Because Ally is a lender, the risk of customers defaulting is paramount. Investors must scrutinize metrics like net charge-offs (the percentage of loans the bank doesn't expect to collect) and provisions for loan losses (money set aside to cover future defaults). A sudden spike in these numbers is a major red flag.

The GMAC Ghost and Modern Risks

While Ally is a fundamentally different company today, the shadow of its past and the nature of its business create specific risks investors must consider.

From Bailout to Banking Powerhouse

The 2008 bailout, while painful, was a blessing in disguise. It forced GMAC to become a regulated bank holding company. This regulatory straitjacket compelled it to build a stable deposit base, weaning it off riskier, more expensive forms of funding. This transformation created the robust, consumer-facing Ally Bank we see today, giving it a significant competitive advantage.

Investing in Ally means being comfortable with several key risks.
