ENPH Bears Stay Active as Earnings Arrive Tonight

Enphase Energy reports Q2 results tonight with short sellers still firmly in the trade, a stock down 20% on the month, and analysts split on whether the solar inverter maker has found its floor.

Short interest has ticked higher since the July 22 preview, reaching 18.1% of free float — about 23.6 million shares as of July 24. That's up roughly 1.8% in one session and 5.5% on the week, extending the rebuild flagged earlier. The lending market remains wide open to new entrants: availability has expanded to 273%, up from the 253% level noted in the prior note, and the cost to borrow is unchanged at roughly 0.44% — essentially free. Bears can add with no friction. Options, by contrast, tell a calmer story. The put/call ratio is 0.71, fractionally below its 20-day average of 0.72, with a z-score near zero. Options traders are not hedging aggressively into the print — the positioning looks neutral rather than fearful.

The analyst debate reflects a stock that has fallen far enough to attract fresh attention but not enough to silence the skeptics. Barclays upgraded to Equal-Weight in June after the stock had already been cut in half, lifting its target from $30 to $51. Bernstein initiated at Market Perform with a $56 target around the same time. TD Cowen moved the other way last week, slashing its target from $70 to $48 while keeping a Hold — a signal that even cautious observers see the near-term risk as meaningful. Goldman holds a Buy with a $57 target. The consensus mean lands near $49, roughly 29% above Monday's close of $38.01, but GLJ Research anchors the bear pole at $21.70. The bull case centres on the company's SST technology, expansion into commercial and data-centre markets, and strong backlog. Bears point to declining residential solar demand as 25D tax credits fade, premium pricing pressure, and competitive threats from non-Chinese inverter vendors stepping into a market reshaped by potential Chinese bans.

The most notable institutional move comes from BlackRock, which added 2.2 million shares as of June 30 to hold 16.8% of outstanding stock — a meaningful conviction add from the largest holder. On the insider side, CEO Badrinarayanan Kothandaraman bought just over 5,000 shares in late May at prices above $67, now well underwater. The stock's most recent comparable earnings reaction was a sharp one: last quarter's print triggered an 11.5% single-day decline before recovering about 2% over the following week. Prior to that, a February print sparked a 26.8% one-day rally.

Tonight's print is effectively a test of whether Enphase's revenue trajectory and margin profile justify a stock that has already lost a fifth of its value in a month — or whether the bears, who have added freely into the weakness, have correctly priced in another leg down.
