ETF analytics confirm net inflows of $210 million into funds tracking the agg stock price this week. These inflows reinforce demand for diversified debt portfolios amid persistent equity market volatility. This fund tracks the Nasdaq 100 index , which includes the 100 largest non-financial companies trading on that Nasdaq stock exchange. If you share the view that U.S. public debt is likely to keep rising, then it makes sense to expect the market to price that risk in. If you also share the view that this will lead to investment-grade corporate bonds outperforming, then the Vanguard ETF is a better option. The agg stock price opened this morning at $99.22 after a mild overnight dip. Quant funds are increasing exposure in anticipation of a policy pause by the Federal Reserve, which historically lifts aggregate bond indexes over the medium term.
