MCC Meili Cloud Computing's high P/S ratio is worrying, given its three-year growth is below industry forecast. Without medium-term performance improvement, the P/S ratio may decline to a more reasonable level.

Despite poor financials and declining revenue, the market's high P/S ratio may be due to hopes of future outperformance. However, this could lead to overpriced stocks. The company's growth rates are weaker than industry average, and without significant medium-term performance improvement, the P/S ratio may decline to a more reasonable level.

Despite declining revenues, the company's high P/S ratio indicates investor optimism. This is, however, risky as ongoing revenue trends could lead to a share price drop, placing investors at a risk of overpaying.
