On other threads on this forum, I have seen the question of 'is selling or buying options better' generally with the answer being, if you sell you get a bunch of small wins and one big loss. If you buy you get a bunch of small losses and one big win. Either way, you don't have an edge. Now, after reading that the thought popped into my mind, why not just sell vertical spreads? You still have a string of small wins, but when those one or two big losses comes, it's only a medium loss for you because you bought the other option, limiting your risk. I'm sure there must be twenty holes that all the super advanced traders on this forum can shoot through this idea. So I'm asking, what would be the problem with this strategy? what are the down sides? looking forward to hearing your responses.
