This is not the first time that Vanguard has cut costs on its popular funds of late.

In February, Vanguard trimmed fees on a handful of ETFs such as the Vanguard Total Bond Market ETF (NasdaqGM: BND), Vanguard FTSE All-World ex-US (NYSEArca: VEU), Vanguard FTSE Europe ETF (NYSEArca: VGK), Vanguard FTSE Pacific ETF (NYSEArca: VPL), Vanguard Tax-Exempt Bond ETF (NYSEArca: VTEB), Vanguard FTSE Emerging Markets ETF (NYSEArca: VWO) and Vanguard Total International Stock ETF (NASDAQ: VXUS), the Wall Street Journal reported.

Despite the recent cuts, Vanguard funds still remaining more expensive than several of the most popular competitor ETF offerings by investment companies such as Schwab, JP Morgan, and State Street.

Still, for those who are waiting on the sidelines, looking for a reason to invest in an ETF, this could be an opportunity to get involved in the markets.
