Some people do that with the VIX as well. Lose most of the time, but VIX has a tendency to spike hard, and so they make money after a long period of losing.The reason some people buy otm wings is so they can have ammo to sell into strength.ie build a condor or turn a backspread into 2 verticals where the pnl graph is all " above the line " regardless of where XYZ ends up 0 DTE.. Willing to take on some vega risk in return 4 curvature for a bigger payoff in the event an underlying has an unanticipated move. Believe it or not there are traders out there with a psychological makeup that is comfortable with losing 70% of the time in return for multiples of winners for the other 30%- Richard Dennis comes to mind. The have modeled it out that owning wings will lose 70% of the time or whatever but in return their avg win is x times greater than avg loss on the 30%.How do they model it out.. that is the secret sauce.. I can tell you . it is most likely not in the option scanner or rankers available off-the-shelf. That "something" could be as simple as a 200d moving avg crossover or something exotic that they only know.
Or like the housing crisis, people buying CDS on MBS lose money every year paying premium until the housing collapse and they rake in hundreds of millions or billions in some cases.
