Dropbox, Inc. (DBX) doesn't have much of a trading history but we can make a couple technical observations. Let's check out a Japanese candlestick chart and a Point and Figure chart.
In this daily candlestick chart of DBX, below, we can see that prices traded sideways in a relatively tight range around $30. This week prices exploded on the upside soaring from $30 to $40. Prices rose and so did volume. Today's candle is currently showing an upper shadow which tells us there is some profit-taking. Things could change by the close but that is what the chart shows now.
In this Point and Figure chart of DBX, below, we also lack much price history but a $64 price target is indicated.
Bottom line: DBX has rallied sharply in a short span of time. Typically, you look for some sideways price action after this kind of sprint. It's like the stock needs to catch its breadth. I would look for a $37-$40 trading range as the next move.
