Molycorp's (MCP, http://stockcharts.com/charts/gallery.html?s=mcp) Intra Day Volume Patterns Look Bullish, see http://finance.yahoo.com/q/ta?t=5d&l=off&z=l&q=c&p=v&a=ss&c=&s=mcp. There was a major volume spike as MCP peaked at 40.90, but, there was an even larger volume spike as MCP bottomed at 32.01 (during the second half of Thursday 10-28's session, MCP crashed to 32.20), and, volume was relatively light as MCP rebounded on Friday 10-29-10.
That being said, there's a good chance that Friday's rebound for MCP and REE is a counter trend Wave B move (see Rare Element Resources (REE) Elliott Wave http://goo.gl/fb/XzaA6), of the Monthly Downcycle since hitting 40.90 for MCP and 14 for REE. MCP might make a run at the downside gap at 28.25. I suspect that REE will at least fill the 10.11 downside gap, and, might (probably won't) make a run at downside gaps at 7.65, 6.70, 5.83, 5.03, 4.55, 4.44, 3.77, 2.80, etc.
REE's (Rare Element Resources, http://stockcharts.com/charts/gallery.html?s=ree) intra day volume patterns probably aren't as bullish as MCP's, but, are probably bullish, see http://finance.yahoo.com/q/ta?t=5d&l=off&z=l&q=c&p=v&a=ss&c=&s=ree.
