Taiwanese car-cooling parts maker Auto Cooler (艾姆勒, 2241) is rallying against a falling market as its sales climb and losses shrink, good news for shareholders who sat through years of red ink.

• Sales for the first seven months rose 46% from a year earlier, the eleventh straight month of growth.
• The stock jumped about 8% to NT$34.5 while the wider market fell.
• Losses narrowed sharply and profit margins turned positive again as its factories ran closer to full capacity.
• Years of losses came from the long testing period for car parts; those new car models are now selling, so the payoff is arriving.
• New orders for North American driver-assistance systems start in the second half, with liquid-cooling products lined up as the next growth push.

Outlook: The company expects to swing to a full-year profit for the first time, with results improving through the rest of the year.
