Two cautions on reading a list like this. A single day's move tells you very little about a business, and small companies move further on less volume — so the top of a gainers list is often the least liquid name rather than the most improved one.

Companies trading within 5% of their 52-week high this week: SHG.

Where a stock sits in its 52-week range is a momentum observation, not a valuation one — a company can sit at a high and still be cheap, or at a low and still be expensive.

The more useful follow-up for a fund investor is which ETFs hold these companies and at what weight, because that is what actually moves your portfolio. Each name above links to that breakdown.
