Humana is a health benefits company that offers coordinated health insurance coverage and related services through a variety of plans for retirees, employer groups, and government-sponsored programs, such as Medicare Advantage and Medicaid. Humana serves approximately 17.7 million medical members, including 6.4 million individual MA members and 4.7 million specialty and dental members. The company's CenterWell health services segment offers pharmacy benefit manager services, home care services, and primary care services. HUM shares are a component of the S&P 500.

The major indices are lower at midday on Tuesday. Several big banks, including Bank of America and JP Morgan, are sending warning signals about stock market valuations. Crude oil is down 4% at $87 per barrel. The yield on the 10-year note is at 4.55% and the VIX volatility index is up to $22.

The stock market was smacked a bit on Wednesday, but the major semiconductor ETFs (SMH and SOXX) still rose 0.9% and 1.8%, respectively. So maybe there's nothing to worry about. Crude oil (WTI) popped another 2.5% in late-day trading to $96.40/barrel, while Brent rose just over 2% to $98/barrel. If WTI breaks above $100 looking out a week, it will bust through the declining trendline off the peaks since April 7. That would most likely nullify a bearish diamond top and open the door for another leg higher -- and potentially new highs for the current rally above $120. Treasury yields won't be happy with that, and the combination will not be equity friendly.

Humana is one of the largest private health insurers in the US, and the firm has built a niche specializing in government-sponsored programs, with nearly all its medical membership stemming from Medicare, Medicaid, and the military's Tricare program. Beyond medical insurance, the company provides other healthcare services, including primary-care services, at-home services, and pharmacy benefit management.
