Several bullish trades were registered on Friday throughout the day. As the stock was breaking out to the 52w high, a trader was buying March $48 and $49 calls. This appears to be either an insider or a bull sweeper who expects higher prices by 15 of March.
Since the volume is way larger than the open interest, we can conclude that this was a new position placed on Friday. The total bullish bet was around $60K.
The price of HOLX closed at the 52w high after breaking above the $45 resistance line.
