### Comment:
They are correct. Airlines a shit investment. Same with oil companies. Why?  
 1) They rely entirely on elastic input costs or revenues. (Price of oil) 
 2) They have ridiculous operational leverage. (Each $ lost in revenue results in an amplified loss to cash flow)

### REPLY:
Depends on which vertical your talking about for oil and gas companies, but generally correct for upstream, that said I’ve made a lot of money the past 6 months in oil companies
