The Accum/Dist technical-indicator is a visual representation of the Accumulation (Buying, "holding"), of a stock versus the Distribution (Selling, "releasing") of stock back into the market.
Anyone can see HHSE has been accumulated with an uptrend (up-sloping trend-line) over a WIDE RANGE of prices (that's important), across the ENTIRE 6yr+ history of the chart. What makes the ACCUMULATION over a price range important is that IT SHOWS HHSE having been BOUGHT at HIGHER PRICES TOO,... & the trend REMAINS to ACCUMULATE (BUY & HOLD) rather than distribute (Sell & liquidate).
