Jones Tech's high P/E ratio is alarming due to its falling earnings. Investors' excessive optimism could be risky if earnings keep declining. The high P/E ratio may not be sustainable considering the company's recent performance.

Jones Tech's low earnings growth, low ROE compared to the industry, and high payout ratio indicating a focus on dividends over growth, make investing in it a potential risk.

Jones Tech's falling ROCE and growing capital employed stir worries. A rebound could occur if new capital enhances returns. Lower current liabilities hint at diminished risk or possibly less efficient ROCE generation.
