Exchange traded funds (ETFs) have been making history this week, as Monday gave way to one of the biggest volume trading days ever. This comes after markets have plunged to three year lows and then, Tuesday end up being a massive volume trading day, as well, reports Jim Wiandt for Index Universe.

ETFs have taken a big role within equity trading, proving that these funds have a presence in the industry.

Jim Wiandt gives us this data for Monday’s volume over the average volume in August:

• All ETFs: Monday-$178 billion vs. $81 billion
• All iShares-$32 billion vs. $16 billion

Financial ETF volume was around three times the average daily volume of the past six months. iShares ETFs really had a chance to shine, as they traded in line with their Indicative Optimized Portfolio Values across all asset classes, taking the volatility and odd volumes in stride.
