"Is [ABC] a good industry to invest in?" Interview question

I recently had an interview where the interviewer gave a two sentence description of a niche industry, then asked me to list out pros/cons and whether I'd invest in a company operating in that industry. They didn't give any further information when asked.

Does anyone have any advice or useful frameworks for these questions? Specifically when they don't give you much info to go off. 

I'm guessing you can use a version of Porter's five forces and just state assumptions very clearly, but really grateful for input from anyone more qualified.
