BLGO’s stock style is Small Core.
Style is an investment factor that has a meaningful impact on investment risk and returns. Style is calculated by combining value and growth scores, which are first individually calculated.

High-growth stocks tend to represent the technology, healthcare, and communications sectors. They rarely distribute dividends to shareholders, opting for reinvestment in their businesses. More value-oriented stocks tend to represent financial services, utilities, and energy stocks. These are established companies that reliably pay dividends.
