The short version

How ENPH and FSLR compare today, and what CleaRank Financial AI makes of it.

The verdict

ENPH and FSLR on the figures that matter most, and which one CleaRank Financial AI prefers today.

-16.2% 1-year change -25.2%
50.5% Volatility (30d, yearly) 58.2%

33.5x P/E ratio 11.0x

The verdict
FSLR wins this head-to-head comparison against ENPH, primarily driven by its superior valuation and profitability metrics. While both companies operate in the renewable energy sector, FSLR presents a more compelling investment case due to its significantly lower P/E ratio and higher profit margins. ENPH's recent revenue contraction and weaker technical indicators further solidify FSLR's advantage. Investors seeking a more attractively priced and profitable player in the solar industry should favor FSLR.
Key difference
The most significant differentiator between FSLR and ENPH is FSLR's substantially more attractive valuation and superior profitability. FSLR's P/E ratio is less than half of ENPH's, and its net profit and return on equity margins are considerably higher. This suggests FSLR is a more efficient and fundamentally sound business that is currently trading at a much more reasonable price, making it the clear winner on valuation and profitability.
Outlook
The outlook for FSLR appears more positive than for ENPH, primarily due to its stronger financial foundation and more favorable valuation. FSLR is expected to benefit from continued demand in the solar sector, supported by its efficient operations and analyst confidence. ENPH faces headwinds from its recent revenue decline and higher valuation, suggesting a more challenging path to recovery. A scenario where FSLR continues its upward trajectory towards its analyst targets while ENPH struggles to regain its footing above key technical levels is plausible.

On valuation
FSLR trades at a P/E ratio of 11.04, which is substantially lower than ENPH's P/E of 33.5. This indicates that FSLR is considerably cheaper on a relative earnings basis. Despite ENPH's higher market capitalization, its valuation multiples suggest a higher growth expectation that is not currently supported by its recent performance. FSLR's price is also trading closer to its 52-week low of $168.60 compared to ENPH's price relative to its $25.78 low, suggesting more downside risk has already been priced in for FSLR. However, its lower P/E ratio makes it the more attractive valuation position.
On profitability
FSLR exhibits superior profitability compared to ENPH. FSLR boasts a net profit margin of 32.47% and a return on equity of 18.51%, significantly outperforming ENPH's net profit margin of 10.09% and return on equity of 13%. FSLR's return on assets at 8.62% also surpasses ENPH's 2.38%. These metrics indicate that FSLR is more efficient at generating profits from its assets and shareholder investments, making it the more fundamentally sound company from a profitability standpoint.

FSLR's RSI is slightly higher at 38.63, but its 20-day EMA is at $182.62, also suggesting a bearish short-term trend. ENPH is trading below its 50-day and 200-day moving averages ($35.76 and $41.20), while FSLR is below its 50-day and 200-day moving averages ($199.63 and $219.84).

Risk
ENPH faces risks related to its recent revenue contraction and its current technical weakness, trading significantly below its 50-day and 200-day moving averages ($35.76 and $41.20). Its lower profitability margins also present a vulnerability in a competitive market. FSLR's primary risks include its own revenue contraction and its current position below key technical averages, although its profitability and valuation offer a buffer. A significant risk for both companies is the cyclical nature of the solar industry and potential shifts in government policy or demand. However, FSLR's stronger financial footing mitigates some of these sector-wide risks.
ProTips
  1. Consider FSLR for its attractive valuation and strong profitability, offering a more defensive profile within the solar sector.
  2. Monitor ENPH's revenue trends closely; a sustained contraction could further pressure its valuation multiples.
  3. Given the current technical weakness in both names, investors may consider waiting for clearer upward momentum signals before initiating or adding to positions.
