Cramer told investors to avoid this stock back in February and he's not changing his position now, despite the rebound. Simply put, there's way too much competition in this space, he said.
Let's call in a delivery of some charts and indicators.
In the daily bar chart of GRUB, below, we can see some slight bottoming price action. I used the word "slight" because while prices have made a some bottoming action in April-early June the indicators are not giving us any confirmation. Trading volume has not increased from April and the daily On-Balance-Volume (OBV) line is still not signaling more aggressive buying.
The Moving Average Convergence Divergence (MACD) oscillator is still above the zero line (barely) but it has crossed to the downside for a take profits sell signal.
In the weekly bar chart of GRUB, below, we can see that prices have retraced approximately two-thirds of the 2017-2018 rally. The 40-week moving average line is in a downtrend and prices are testing the underside of the average line.
The weekly OBV line shows an irregular rise so far this year with weakness in recent weeks. The MACD oscillator is still below the zero line.
In this Point and Figure chart of GRUB, below, we can see a potential downside price target around $68. A rally to $79.84 is needed to turn this chart bullish.
Bottom-line strategy: I agree with Cramer that GRUB is still not an attractive purchase. Look for opportunities elsewhere.
