This move has also pushed SAND into overbought territory, since its current relative strength index reading is now 82. Overbought can always get more overbought in the short-term for any stock. With that in mind, traders should now look for long-biased trades in SAND as long as it's trending above $11.50 with strong upside volume flows. I would consider any upside volume day that registers near or above 138,636 shares as bullish. If we continue to see SAND hold that trend, then this stock could hit $15 or higher in the near future.
