Should you invest in BlackRock or Vanguard products?

Both BlackRock and Vanguard offer a diverse range of products that caters to many different types of investors. When it comes to low-cost index funds, both BlackRock and Vanguard have very competitive offerings and there’s usually not much difference between comparable ETFs issued by the two companies. 

For example, you’re going to see practically the same investment results if you pick BlackRock’s iShares Core S&P 500 ETF or Vanguard’s S&P 500 ETF, as they both track the same index and have the same 0.03% expense ratio. Both BlackRock and Vanguard are highly reputable asset management companies. 

When it comes to passively managed index funds, the short answer is that it doesn’t really matter if you pick a BlackRock ETF or a Vanguard ETF if both products have the same investment objectives and the same expense ratio. In order to directly compare ETFs according to their most important characteristics, we suggest you use an ETF screener.

In some cases, Vanguard might offer certain investment products that have no equivalent in BlackRock’s offering and vice versa. For example, BlackRock issues the iShares Gold Trust, which has no real equivalent in Vanguard’s product offering.

One interesting thing to point out when it comes to BlackRock vs. Vanguard is that BlackRock has launched Bitcoin ETFs, while Vanguard is currently unwilling to launch investment products tied to cryptocurrency. So, if you’re a cryptocurrency supporter, you might be more inclined to invest in BlackRock’s products to reward the company for being open to crypto. 

Overall, BlackRock offers a more diverse range of investment products compared to Vanguard, so you’ll probably be able to find a suitable product even if you have very specific investment needs. Still, for most investors, there is practically no difference between BlackRock and Vanguard when it comes to comparable ETFs.
