Trina Solar vs Kioxia: why the prices moved differently

• ▲

  Module gross margin turns positive Trina's panel-making business made a gross profit of 226 million yuan in the first half, a 1.27% margin — its first positive gross margin since 2025. This matters because it shows the core business is finally earning money on each panel sold, not just relying on one-off asset sales.

  This is the clearest sign that Trina's main business is recovering, directly supporting the stock.

• ▲

  Beijing moves to end cutthroat price wars Regulators held a price compliance meeting and released unified cost accounting rules, with mandatory national standards coming in 2027. The goal is to stop panel makers from selling below cost, which could lift prices and help all producers, including Trina, become profitable again.

  This policy shift could reverse the industry's loss-making price war, a major force behind Trina's stock.

• ▲

  New power system plan boosts long-term demand China's 15th Five-Year Plan for new power systems aims for non-fossil fuels to supply 50% of electricity by 2030. This supports future solar demand, and Trina is a top holding in the new energy ETF that rose on the news, drawing investor attention to the sector.

  It shows a policy-driven demand tailwind that benefits Trina as a major solar maker.

• ▼

  Industry-wide losses and zombie project cleanup Five solar giants still lost over 13 billion yuan combined in the first half, and 1,266 idle solar projects are being purged nationwide. This shows the industry remains deep in oversupply, and the cleanup, while healthy long-term, adds uncertainty and pressure on weaker players like Trina.

  It is the main counterweight: the industry is still losing money and clearing excess capacity, which can hurt near-term profits.

This opens a large new customer base beyond home solar, supporting future demand.

  New strategic expansion into AI data center power, a fresh demand driver.

• ▼

  Core business still losing money Trina's first-half forecast shows a net loss of 180-360 million yuan, much smaller than last year, but the loss excluding one-off items is still up to 2.96 billion yuan, roughly flat. That means the actual panel-making business is not yet profitable, a real drag on the stock.

  New earnings forecast revealing core profitability remains weak despite headline improvement.

• ◆

  Profit boost from asset sales, not operations The narrower headline loss came largely from selling equity stakes and investment gains, not from selling more panels profitably. Storage and distributed systems did contribute positively. Investors should note the improvement is partly one-off, so it may not repeat.

  Clarifies that reported profit improvement is partly non-recurring, a counterweight to the positive headline.
