What is Mizuho Financial Group GF Value Rank?

Mizuho Financial Group has the GF Value Rank of 1.

GF Value Rank evaluates the exclusive GuruFocus valuation and performance of a stock, rated on a scale from 1 to 10. It is determined by the price-to-GF-Value (P/GF Value) ratio, a proprietary metric calculated based on historical multiples along with an adjustment factor based on a company's past returns and growth and future estimates of the business' performance.

GuruFocus found that for valuation, we cannot simply give stocks a better GF Value rank simply because they have a lower P/GF Value ratio. Backtesting shows that over the long term, the two worst-performing groups are the most expensive group (with the highest P/GF Value ratio) and the least expensive group (with the lowest P/GF Value ratio).

We can understand why the most expensive group underperforms. We were initially puzzled by the underperformance of the least expensive group, but we realized there is a reason why some stocks are super cheap. If they look too undervalued, it is often because the businesses behind them are poor quality. The market realized this and gave them low valuations. In a way, the market is efficient.

After multiple backtesting analyses, we granted the stocks in third-cheapest percentile the highest GF Value rank, as they have performed the best over a full market cycle. Stock performance is actually not as sensitive to valuation as it is to growth and profitability. On average, the companies in the 20%-50% valuation groups have similar performances. Therefore, we should avoid the most expensive and the least expensive stocks. We can be more tolerant of valuation.

A higher score indicates a stock with a relatively low valuation and substantial potential for outperformance. Conversely, a lower score often reflects stocks that are either highly overvalued or deeply undervalued, both of which tend to underperform.

Mizuho Financial Group Business Description

Address 1-5-5, Otemachi, Otemachi Tower, Chiyoda-ku, Tokyo, JPN, 100-8176
Mizuho Financial Group is roughly tied with megabank peer Sumitomo Mitsui Financial Group for the status as Japan's second-largest bank after Mitsubishi UFJ Financial Group. In Japan, Mizuho has more of a corporate focus than SMFG, which has a larger retail business. Its overseas weighting is slightly smaller than that of MUFG. Unlike its two Japanese megabank peers, which own foreign banks outright or hold noncontrolling stakes in local banks overseas, Mizuho expanded in recent years beyond its traditional Japanese borrowers, mainly through its core banking and securities units, focusing on the financing needs of global multinational corporations.
