Lifeway Foods' high P/S ratio is backed by its promising revenue outlook. Investors see little chance of revenue decline, supporting the high P/S ratio and strong share price, but they should also be aware of certain risks.

Insider's recent share sale, even below current price, implies belief in full valuation. High insider ownership aligns management's incentives with shareholders. Lack of insider buying and recent selling raises caution.

Insider sales at prices higher than current value suggest that Lifeway Foods' shares may be overvalued. Despite high insider ownership indicating shareholder interest, the sales trend is concerning.
