Health care stocks were mostly underwater just ahead of Monday’s closing bell, with the NYSE Health Care Index slipping nearly 0.9% while shares of health care companies in the S&P 500 also were down almost 0.9% as a group.

In company news, Medigus (MDGS) American depositary shares turned lower this afternoon, giving back earlier gains that followed the Israeli surgical tools manufacturer today narrowing its Q3 net loss compared with year-ago levels.

The company recorded an unadjusted operating loss of $1.9 million during the three months ended Sept. 30, improving on a $2.3 million net loss during the same quarter last year. Net sales dropped 43% from last year to $136,000. No analyst estimates were available for comparison.

The company earlier today also said European authorities have given preliminary approval for its bid to patent its micro ScoutCam miniature camera technology. If officially granted, this patent will be valid until September 16, 2030.

MDGS shares were down nearly 6% at 91 cents apiece, recovering somewhat from a prior drop as low as 86 cents a share today and following an early-morning rise to $1.05 a share.
