Much of the climb in solar stocks looks justified by growth prospects, but buyers may still be in for a bumpy ride
2 min
Solar stocks are sizzling—quite an accomplishment for the simplest and most mature of the green-energy technologies. Finding companies that could keep shining might require looking in less obvious places.
The MAC Global Solar Energy Index has generated a 233% return including dividends for dollar investors during the past year. That is well ahead of returns from wind-turbine makers Vestas and Siemens Gamesa, nevermind the S&P 500’s 15%.
As public and political support for green power has broadened, markets have come to expect a decadeslong renewables rollout. It is hard to see any catalyst for a change in sentiment, says Sam Arie, a veteran utilities analyst at UBS. Solar panels can be the cheapest way to generate electricity in many parts of the world. “In some cases it is even cheaper to build a new solar farm than run existing coal plants,” says Alex Monk, a portfolio manager at asset manager Schroders.
The catch is that the shift to renewables doesn’t guarantee shareholder returns. To justify high valuations, investors need to ensure companies have a defensible business as well as growth prospects.
Solar investors have already experienced at least two stomach-churning cycles. A key lesson has been that making panels themselves is a low-margin, hypercompetitive market best avoided. But other parts of the value chain offer better prospects.
For example, SolarEdge and Enphase make power inverters, which convert a solar panel’s power to alternating current and adjust performance to maximize output. Their Nasdaq-listed shares have returned 179% and 444% respectively during the past year and now trade for 72 and 93 times forward earnings. That is a lot of growth priced in. However, the technologies are patent-protected and could also be central to managing a smart home’s power between electric vehicles, solar panels, batteries and the like—a potentially vast market.
Developers are another option. They bid for, build and run solar farms. While installing the panels isn’t complex, experience is valuable when pricing bids and navigating the permitting process, and scale is crucial to sourcing panels effectively.
NextEra Energy, Enel and Iberdrola have built huge renewable-power farms as part of wider utility businesses and have ambitious rollout plans for solar and wind. Their shares have given investors total returns of between 16% and 28% over a year, and now change hands for between 15 and 32 times forward earnings. Barclays utilities analyst Dominic Nash credits part of the rise to general growth investors coming into the sector for the first time.
Then there are U.S. residential developers, which offer homeowners rooftop solar-panels paired with battery storage. The products provide added reliability, and monthly payments for the cost of batteries and solar panels that are often lower than existing utility bills. “It’s a pretty easy sale,” says Stephen Byrd, an analyst at Morgan Stanley.
Shares in SunPower and Sunrun, two such developers, trade at Tesla-type multiples, 118 times and 360 times forward earnings respectively. Revenues will grow—U.S. solar penetration will rise from 3% now to 14% by 2030, says Mr. Byrd—but margins will also come under pressure once installers compete head-to-head rather than with incumbent utilities.
Investors need to choose carefully as the stock-market solar coaster speeds up again. The general direction of travel may be up, but it likely still has plenty of twists and turns in store.

U.S. investors’ enthusiasm over Japanese stocks at this time last year turned out to be misplaced, but the market is again on the list of potential ways to diversify. Corporate shake-ups, hints of inflation after years of declining prices, and a trade battle could work in its favor.
Japanese stocks started 2024 off strong, but an unexpected interest-rate increase in August by the Bank of Japan triggered a sharp decline that the market has spent the rest of the year clawing back. Weakness in the yen has cut into returns in dollar terms. The iShares MSCI Japan ETF , which isn’t hedged, barely returned 7% last year, compared with 30% for the WisdomTree Japan Hedged Equity Fund .
The market is relatively cheap, trading at 15 times forward earnings, about where it was a decade ago, and events on the horizon could give it a boost. Masakazu Takeda, who runs the Hennessy Japan fund, expects earnings growth of mid-single digits—2% after inflation and an additional 2% to 3% as companies return more to shareholders through dividends and buybacks.
“We can easily get 10% plus returns if there’s no exogenous risks,” Takeda told Barron’s in December.
The first couple months of the year could be volatile as investors assess potential spoilers, such as whether the new Trump administration limits its tariff battle to China or goes wider, which would hurt Japan’s export-dependent market. The size of the wage increases labor unions secure in spring negotiations is another risk.
But beyond the headlines, fund managers and strategists see potential positive factors. First, 2024 will likely turn out to have been a record year for corporate earnings because some companies have benefited from rising prices and increasing demand, as well as better capital allocation.
In a note to clients, BofA strategist Masashi Akutsu said the market may again focus on a shift in corporate behavior that has begun to take place in recent years. For years, corporate culture has been resistant to change but recent developments—a battle over Seven & i Holdings that pits the founding family and investors against a bid from Canada’s Alimentation Couche-Tard , and Honda and Nissan ’s merger are examples—have been a wake-up call for Japanese companies to pursue overhauls. He expects a pickup in share buybacks as companies begin to think about shareholder returns more.
A record number of companies have also delisted, often through management buyouts, in another indication that corporate behavior is changing in favor of shareholders.
“Japan is attracting a lot of activist interest in a lot of different guises, says Donald Farquharson, head of the Japanese equities team for Baillie Gifford. “While shareholder proposals are usually unsuccessful, they do start in motion a process behind the scenes about the capital structure.”
For years, money-losing businesses were left alone in large corporations, but the recent spate of activism and focus on shareholder returns has pushed companies to jettison such divisions or take measures to improve them.
That isn‘t to say it is going to be an easy year. A more protectionist world could be problematic for sentiment.
But Japan’s approach could become a model for others in this new world. “Japan has spent the last 30 to 40 years investing in business overseas, with the automotive industry, for example, manufacturing a lot of the cars in the geographies it sells in,” Farquharson said. “That’s true of a lot of what Japan is selling overseas.”
Trade volatility that hits Japanese stocks broadly could offer opportunities. Concerns about tariffs could drag down companies such as Tokio Marine Holdings, which gets half its earnings by selling insurance in the U.S., but wouldn’t be affected by duties. Similarly, Shin-Etsu Chemicals , a silicon wafer behemoth that sells critical materials, including to the chip industry, is another potential winner, Takeda says.
If other companies follow the lead of Japanese exporters and set up shop in the markets they sell in, Japanese automation makers like Nidec and Keyence might benefit as a way to control costs in countries where wages are higher, Farquharson says.
And as Japanese workers get real wage growth and settle into living in an economy no longer in a deflationary rut, companies focused on domestic consumers such as Rakuten Group should benefit. The internet company offers retail and travel, both of which should benefit, but also is home to an online banking and investment platform.
Rakuten’s enterprise value—its market capitalization plus debt—is still less than its annual sales, in part because the company had been investing heavily in its mobile network. But that division is about to hit break even, Farquharson says.
A stock that stands to benefit from consumer spending and the waves or tourists the weak yen is attracting is Orix , a conglomerate whose businesses include an international airport serving Osaka. The company’s aircraft-leasing business also benefits from the production snags and supply-chain disruptions at Airbus and Boeing , Takeda says.
An added benefit: Its financial businesses stand to get a boost as the Bank of Japan slowly normalizes interest rates. The stock trades at about nine times earnings and about par for book value, while paying a 4% dividend yield.
Corrections & Amplifications: The past year is expected to turn out to have been a record one for corporate earnings in Japan. An earlier version of this article incorrectly gave the time frame as the 12 months through March. Separately, Masashi Akutsu is a strategist at BofA. An earlier version incorrectly identified his employer as UBS.
