JA Solar Technology's low P/E ratio is due to its poor earnings outlook. The low ratio reflects investors' lack of confidence in the company's earnings potential, implying a stagnant share price in the near future.

Despite recent decline in JA Solar Technology's stock, its strong financials indicate a positive long-term perspective. High ROE and remarkable net income growth are promising. The company's effective reinvestment strategy may drive its growth despite anticipated slowdown in earnings growth rate.

JA Solar Technology is promising due to high EPS growth, improved EBIT margins, and revenue growth. While insider investment is positive, caution is advised due to certain warning signs.
