The first 2 companies look promising - people will continue to take care of their pets in a recession, even if it entails less frivolous care,  and a fossil fuels play in virtually untapped Poland sounds like a potentially very solid hit.   The last 3, I'm not so sure. 

Home security systems - a lot of people are cutting their cable TV subscriptions, landline phones, etc. just to make ends meet in this recessionary economy, and if unemployment stays level or increases, I see a lot of middle class/upper middle class folks in safe neighborhoods deciding that they really don't need home security anymore.  People are starting to realize that contracts suck.  A lot of people from all walks of life, including professionals in the affluent suburbs, are walking away from lawn service contracts, landline for cell phones or Ooma-type internet phones, ditching cable for streaming video subscriptions, etc., so folks will opt out of rather expensive home security contracts for other security methods dependent on their level of comfort with neighborhood crime rates or lack thereof  (gun purchase, lighting systems, dog, fake dog bark, non-subscription alarms and motion detectors, cameras/surveillance​, glass block basement windows, etc.)

The high fructose corn syrup play also leaves me skeptical, with significant forces in place combating HFCS in terms of its health consequences and impact in glycemic index, diabetes, and obesity, especially in the diet of children.  So I expect demand to be way down in the near future. 

Finally, the gambling casino machine play really scares me.   Been to Foxwoods or Mohegan Sun in CT near NYC lately?  I haven't been to Vegas in a number of years, but I almost have to assume that they're taking a big hit in gambling revenue and volume of customers/gamblers too.   A sour economy leaves people with less $$ to gamble.  The author of this article does note this element of risk.
