Share price is only part of Vanguard’s decision

While investors may assume that higher share prices alone would justify splits, Vanguard said it considers multiple factors. In its announcement, the firm stated: “A number of factors are considered, including ETF market price, bid-ask spread, and trading volume.”

According to the article, the five ETFs selected for splits have lower trading volume and slightly wider bid-ask spreads than VOO and VTI. The implication is that Vanguard is targeting market microstructure frictions, not simply lowering the sticker price.

Bid-ask spreads and trading volume as the “hidden cost”

The bid-ask spread reflects the difference between what buyers are willing to pay and what sellers are asking. The article notes that each trade effectively involves paying about half the spread as a transaction cost.

It cites examples of how spreads can differ across funds: for VOO, the cost is described as roughly a penny per share, while for VOOG it can run as high as $0.45. The article argues that, even if these spreads are small in percentage terms, they can still matter for a firm focused on minimizing costs.

As an illustration, the article states that buying 100 shares of the Vanguard S&P 500 Growth fund with a $0.45 spread would cost $22.50 to market makers, and that this “donation” is not tax-deductible.

Why VOO and VTI were not split

The article characterizes VOO as already highly efficient, suggesting it does not need additional help at this point. It similarly notes that VTI was not included, despite its share price being above $300.

In contrast, the five funds on the split list are described as “good, but not quite that excellent,” with the expectation that lower share prices could attract more trading activity, increase volume, and tighten bid-ask spreads.

What investors should expect after the split

If an investor already holds any of the five ETFs, the split does not change the total value of the position. Investors will receive more shares at a proportionally lower price, with no tax consequences and no action required.

For investors looking to enter, the article says the minimum buy-in will drop. After the splits, shares of the listed ETFs are expected to be available for under $90 (assuming prices do not move sharply in the weeks leading up to the effective date). This could make it easier to dollar-cost average, complete an incomplete position, or add exposure without committing hundreds of dollars per share.
