Recommendation

BCA Research advises investors to implement a three‑month mean‑reversion trade by taking a long position in an equal‑weighted basket of Chinese Investable and A‑shares and simultaneously shorting South Korea’s benchmark KOSPI index.

Market Outlook

The firm projects that the KOSPI could decline an additional 15 % to 20 % from current levels before reaching its 200‑day moving average. Market breadth in South Korea has deteriorated, with only about 20 % of KOSPI constituents trading above their 200‑day moving averages, versus roughly 30 % for Chinese A‑shares and offshore H‑shares.

Rating Changes

BCA upgraded Chinese Investable stocks to “overweight” within emerging‑market and global‑equity portfolios and downgraded South Korea to “underweight,” after previously moving the Korean rating from “neutral” to “underweight” in late June.

Drivers of the Korean Pull‑back

The recommendation follows a speculative rally in South Korean equities that peaked on 22 June, driven by heightened retail participation through leveraged exchange‑traded funds, margin loans and short‑term options. Foreign investors have been net sellers of Korean equities, adding to the vulnerability of the index to panic‑driven liquidation.

Caveats

BCA cautions that the tactical rotation is not a multi‑year structural shift; it notes that medium‑ to long‑term earnings growth for South Korean hardware manufacturers is expected to remain superior to that of Chinese technology, media and telecommunications (TMT) firms.

Chinese Market Context

While Chinese equities present a mean‑reversion entry point, broad corporate earnings in China continue to contract due to weak domestic demand, price competition and deflationary pressures. The outperformance within China’s on‑shore A‑share market is concentrated in a limited set of AI‑related hardware companies that benefit from global artificial‑intelligence investment, and BCA warns that much of the optimism is already reflected in elevated valuations.

Valuation Highlights

The note lists four mainland‑listed AI hardware suppliers with extreme trailing price‑to‑earnings multiples:

  • Cambricon Technologies Corp Ltd – trailing P/E 209
  • Accelink Technologies Co Ltd – trailing P/E 136
  • Zhongji Innolight Co Ltd – trailing P/E 61
  • Eoptolink Technology Inc Ltd – trailing P/E 52

These valuations suggest limited upside beyond the mean‑reversion premise.
