Amid the market turmoil, exchange traded funds (ETFs) still are coming out ahead. $13.2 billion of net inflow has gone into U.S. ETFs during last week through Thursday, according to TrimTabs Investment Research. Vincent Deluard, a TrimTabs analyst, adds that the $13.2 billion accounts for about 4.2% of all assets held in U.S. stock funds, making this the biggest weekly inflow for 2007.

Murray Coleman for MarketWatch reports the biggest winner was SPDRs (SPY), the original ETF, brought in an estimated $4.6 billion in assets. iShares Russell 2000 (IWM) came in second, with about the same assets as SPY. Some investors say these figures represent a bullish sentiment among institutional traders. Maybe the worst is behind us for now?
