During the fast-paced "Lightning Round" segment of Mad Money Monday evening, one caller asked Jim Cramer about Builders FirstSource (BLDR) : "This one is trading very well," said Cramer. One caller during the Lightning Round back on February 5 asked Cramer about BLDR and we wrote that "Overall the charts of BLDR are mixed. In the short-run we might see a decline to the $23 area and that could become a buying opportunity as our long-term Point and Figure chart looks pretty bullish. Remain flexible."
Prices did decline after our review but fell much more than we anticipated. Let's check and see what the charts of this supplier of building products look like now.
In this updated daily bar chart of BLDR, below, we can see that prices have come "roaring" back from the March nadir. Prices have tripled from that low and look capable of further gains. BLDR is trading above the rising 50-day moving average line and the rising 200-day moving average line. We can see a bullish golden cross of these two indicators at the beginning of August.
The On-Balance-Volume (OBV) line bottomed in April-May and showed improvement until a recent sharp spike in volume (a large volume down day can quickly alter the direction of the OBV line). This development bears further watching.
The Moving Average Convergence Divergence (MACD) oscillator is still bullish but could cross to a take profits signal in the days ahead.
