Analyst upgrades tend to follow cycle turns, not lead them.

In August 2025, in “Enphase Energy (ENPH): An Asymmetric Solar Challenger in a Post-Boom Lull,” we argued that Enphase was not a broken solar stock, but a high-quality platform sitting in a post-boom trough. Our work focused on margin durability, balance sheet strength, and rising storage attach rates as indicators that the cycle was resetting, even as consensus remained anchored to near-term demand softness and policy noise.

In the months that followed, management grew more comfortable discussing the outlook beyond the near term. In late October, they explicitly framed Q1 2026 as the cycle trough, pointing to improving conditions through the remainder of the year, supported by rising power prices, easing interest rates, and the emergence of new financing solutions to offset the expiration of 25D.

By January 2026, sell-side views began to converge. Goldman Sachs upgraded Enphase to Buy, citing stronger-than-expected demand and improving forward visibility, while Citigroup moved the stock from Sell to Neutral, noting limited downside and a reset in risk-reward. The underlying thesis hasn’t changed, the market is simply arriving at it later.
