My guess is that there were people who had stops set at just under $6. Have a look at an OHLC or candlestick chart of RIV over the last two months and you'll see a lot of support at $6. When it dropped below $6, I reckon a few people were stopped out and perhaps some of them are buying back in at that level when it gets there, preventing it cracking above that level.

If that's the case, we watch for the breakout. If it's not, I guess I'm holding some hope that there's some kind of triangle forming over the last couple of days and that it will break in the direction of the six month trend - up.
