RE: Raulston thinks BCM has the goods...Thanks for conveying Roulston's latest thoughts!
No doubt, in some cases, stocks like these are being manipulated.
but I think most of the time these speculative mining stocks just run up to the next drill results, then subside as the bids dry up. This doesn't require much selling pressure. I think you can see that in this stockcharts.com stock. Explanations of top and bottom charts down below, courtesy of Stockcharts.com. By the way, the weakest thing I see about this chart is that the BCM price has dipped below the 50 day moving average. That not good!

Top chart is On-balance volume with a 50 day moving average.
Joe Granville introduced the On Balance Volume (OBV) indicator in his 1963 book, Granville's New Key to Stock Market Profits. This was one of the first and most popular indicators to measure positive and negative volume flow. The concept behind the indicator: volume precedes price. OBV is a simple indicator that adds a period's volume when the close is up and subtracts the period's volume when the close is down. A cumulative total of the volume additions and subtractions forms the OBV line. This line can then be compared with the price chart of the underlying security to look for divergences or confirmation.

Bottom chart is Chaikin Money Flow oscillator with a 20 day moving average. This is calculated from daily readings of the Accumulation/Distribution Line. The basic premise behind the Accumulation Distribution Line is that the degree of buying or selling pressure can be determined by the location of the close relative to the high and low for the corresponding period (Closing Location Value). There is buying pressure when a stock closes in the upper half of a period's range and there is selling pressure when a stock closes in the lower half of the period's trading range. The Closing Location Value multiplied by volume forms the Accumulation/Distribution Value for each period.
