Noble Corp is an offshore drilling contractor. 
Offshore drillers have experienced a period of high distress following the multi-year decline of crude oil.
Noble has a respectable backlog and is trading at lower price multiples as compared to peers.
If crude oil manages to sustain the recent price rise above $50, Noble and others may prove to be a bargain.

Noble is a High-Risk: High-Reward Investment whose risks must be seriously weighed before initiating a position. 

Senior Housing Properties Trust (SNH) is a healthcare REIT strongly positioned to capitalize on aging demographic trends.
At these price levels, the stock is offers an attractive yield with limited downside price-risk.

The company has made significant investments in their transportation network and is sitting on large amounts of high-quality 'northern white' silica reserves. 

The more I look into Qualcomm, the less I like it.
There are many risks to the future profitability of the company including regulatory scrutiny, customer pushback, intellectual property enforcement, as well as an arms race for the development of future 5G technologies.

I would not put money to work today in QCOM and would prefer to invest in better chip manufactures such as Micron.
