Thinking about what to do with Bank of Nova Scotia stock right now? You are not alone. Whether you already own shares or are just eyeing them from the sidelines, it is hard not to take notice when a big Canadian bank posts strong results over both the short and long term. Bank of Nova Scotia ended the last session at $89.32, and if you take a step back, the stock has returned 15.6% year-to-date and a whopping 107.3% over five years. Even in the past year, it is up 27.8%, easily outpacing the benchmark TSX index.

Some of this performance has tracked broad improvements in economic confidence as central banks have stabilized rates and investors have become more comfortable with the outlook for Canadian banks. Over the past three years, the stock is up 65.6%, making it hard to ignore for anyone looking for steady growth with some yield potential. Short-term moves have been more subdued, gaining just 0.5% in the last week and 0.4% over the past month, which perhaps reflects a period of consolidation after such strong longer-term gains.

But what about value? By our count, Bank of Nova Scotia is undervalued by only 1 out of 6 key metrics on our valuation scorecard. In other words, while the run-up is impressive, true bargains might be getting harder to find after this recent surge in price.

Stay tuned for one approach that stands out even more as the smartest way to decide.

The price-to-earnings (PE) ratio is a well-established measure for valuing consistently profitable firms like Bank of Nova Scotia. This metric helps investors understand how much they are paying for each dollar of company earnings, making it especially relevant for stable banks with predictable profitability.

Growth expectations and risk play an important role in what constitutes a "normal" or "fair" PE ratio. Companies expected to grow rapidly or with lower risk can justify higher PE ratios, while those facing headwinds or higher risk may trade at lower multiples.

Currently, Bank of Nova Scotia trades at a PE ratio of 16.61x. For context, the average among its closest peers stands at 13.42x, and the broader banking industry average is lower at 10.19x. While this might seem expensive compared to these benchmarks, it is crucial to account for company-specific factors that impact valuation.

Simply Wall St’s proprietary “Fair Ratio” addresses this by adjusting for Bank of Nova Scotia’s growth prospects, risks, profit margins, industry, and size. The Fair Ratio for the stock is calculated at 14.96x, reflecting a more nuanced view of where the PE should be based on fundamentals rather than blunt averages.

Because Bank of Nova Scotia’s actual PE of 16.61x is moderately above its Fair Ratio, the shares appear to be trading at a slight premium when these company-specific factors are considered.

Result: OVERVALUED
