This market just insists on hanging onto its momentum. Earnings didn't justify the runup (ie. INTC, WMT). Economic numbers released this weak aren't all that strong and don't signal an imminent turn. The dollar languishes. Anyone care to speculate what the people buying are thinking at this point after a 20% runup into historically overbought territory by some indicators? My guess - ponzi mentality (buy higher, sell higher...hopefully) & performance chasing. climbing that wall of worry. short covering. Sure the relative strength in the market is healthy. But is the foundation?!? Does it really matter then?!?!?!?!
