The diminishing returns on increasing amounts of capital at Triductor Technology (Suzhou) are concerning. Unless the underlying trends revert to a more positive trajectory, it might be advisable to consider other investment options.

Triductor Technology's high P/E ratio is due to investors' anticipation of robust future growth, despite recent earnings drop. The possibility of earnings worsening isn't seen as enough to warrant a lower P/E ratio, thus a significant share price drop is unlikely soon.

Despite Triductor Technology's moderate estimated revenue growth compared to the broader industry, investors still favor the stock. Caution is advised, as the current P/S ratio based on limited anticipated growth might not be sustainable, potentially leading to a share price downturn and negative investor sentiment.
