Lumos Diagnostics Holdings Limited (ASX:LDX) shareholders won't be pleased to see that the share price has had a very rough month, dropping 27% and undoing the prior period's positive performance. Regardless, last month's decline is barely a blip on the stock's price chart as it has gained a monstrous 356% in the last year.

Although its price has dipped substantially, Lumos Diagnostics Holdings may still be sending strong sell signals at present with a price-to-sales (or "P/S") ratio of 9.1x, when you consider almost half of the companies in the Medical Equipment industry in Australia have P/S ratios under 6x and even P/S lower than 2x aren't out of the ordinary. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.
