What this transaction means for investors
The May 11 purchase of 15,000 Pulse Biosciences stock by CEO Paul LaViolette signals his conviction that shares will go up in value. This action contributed to Pulse stock reaching a 52-week high of $27.98 on May 14, just days after LaViolette’s buy.
Pulse Biosciences is still developing its medical technology. It announced on May 4 that it would shift its focus to its nPulse Cardiac Catheter System after delivering what it called “landmark” clinical trial results. The company is now working on further clinical trials with patient enrollment expected to be complete by the fourth quarter of this year.
Since Pulse Biosciences is still testing its technology, it doesn’t make much revenue. In the first quarter, it notched $401,000 in sales while posting a net loss of $18.6 million. Its Q1 cash and equivalents totaled $68.3 million, which should sustain operations for a time.
The question is how soon Pulse Biosciences can get government approval for its therapies. LaViolette’s buy suggests he is confident the company can continue to see encouraging progress in the quarters ahead.
