This stock is trading up 3.5% at $57.82 in recent trading. Today's Volume: 408,000 Average Volume: 429,586 Volume % Change: 59% From a technical perspective, LUFK is moving sharply to the upside here with decent volume, and this stock has started to take out its 50-day moving average of $56.43. Traders should continue to look for long-biased trades as long as LUFK is trending above its 50-day with strong upside volume flows. I would consider any upside volume day that registers near or above 429,586 shares as bullish. If LUFK can hold this trend above its 50-day, then this stock could continue to spike higher and possibly take out its next significant overhead resistance levels at $60.20 to $61.87. If those levels are taken out with volume, then LUFK could re-test its 200-day moving average of $67.03.
