  • The firm argued that the move was “a narrative-and-positioning event, not a fundamental re-rating.”
  • Enphase Energy launched a new technology for battery systems across the United States, Puerto Rico, Canada, Mexico, and select Central American and Caribbean countries.
  • The firm said the technology could translate into savings of up to $2,000 over the lifetime of the battery system.

Shares of Enphase Energy (ENPH) slid nearly 6% on Monday as a bearish brokerage call urging investors to exit the stock halted a blistering three-session rally that had sent the stock soaring to a fresh 52-week high.

The rally in ENPH drove the stock up more than 41% over the past three trading sessions.

Why Is GLJ Bearish On ENPH?

GLJ Research noted that ENPH rallied despite “no earnings event, no guidance, no signed customer, no announced product, and no change in their core residential-solar end market,” according to The Fly.  

The firm argued that the move was “a narrative-and-positioning event, not a fundamental re-rating,” adding that a closer reading of the broader story “does not support the move.”

GLJ concluded by stating that investors should “use the rally as an exit, not an entry,” and reiterated a ‘Sell’ rating.

ENPH Launches New Battery Tech

On Monday, Enphase Energy launched a new technology for battery systems across the United States, Puerto Rico, Canada, Mexico, and select Central American and Caribbean countries.

According to the company’s testing, PowerMatch can reduce energy losses by up to 1 kilowatt-hour per day for a typical California homeowner compared with certain competing systems. Enphase Energy said the technology could translate into savings of up to $2,000 over the lifetime of the battery system.

In late April, the company reported better-than-expected fiscal first-quarter (Q1) results, with revenue of $282.9 million, above Wall Street’s estimate of $282.4 million, according to Fiscal.ai data. Earnings came in at $0.47 per share against consensus estimates of $0.45.
