Here is a list of the top-10 ETFs that experienced the largest percentage increase in value traded for the week ending April 17, 2009.
To create the list, I first screened for ETFs and ETNs that had an Average Daily Value Traded (ADVT) of at least $1 million for the past 21 market days. This includes only those products in the upper ETF Liquidity Tiers and represents approximately 45% of the universe of US-listed ETFs and ETNs. This step eliminates many of the peculiarities associated with low volume securities.
Next, I compared the ADVT of the past week to the 50-day average to determine which ones had the largest spike in the past week – an indication of potential increased interest from investors and traders.
