During the Lightning Round segment of Mad Money Wednesday evening one caller got to ask Jim Cramer about Generac Holdings (GNRC) . "This is a stock I like very much. Please do not sell that stock," Cramer replied.
We covered GNRC on May 18 and wrote that "After Superstorm Sandy I did check out buying a Generac generator but I did not purchase it. Today I looked at the charts of GNRC and I am again suggesting deferring purchases for the time being."
Let's check out the charts again.
In the daily bar chart of GNRC, below, we can see that the shares were weak in May but turned strong in June and broke out above the February highs. GNRC is trading above the rising 50-day and 200-day moving average lines.
The daily On-Balance-Volume (OBV) line has been very strong from May and is close to making a new high. A rising OBV line tells us that buyers of GNRC are more aggressive and heavier volume is being traded on days when GNRC has closed higher.
The Moving Average Convergence Divergence (MACD) oscillator is in a bullish alignment above the zero line.
