Well, I can't make a 500th post without a first post preceding it. But post count is not indicative of literacy here or elsewhere.
Can you identify the errors and misapprehensions you mention?...clearly and exemplary? You're quite good at implicit insults, but somewhat unhelpful with constructive criticism (which isn't to say you haven't offered something helpful already).
For some context, I do insurance for my day job--and a specific niche thereof that each account must be profitable on it's own vs. aggregated with similar type accounts as is typical of insurance markets generally. It's entirely possible I take certain metrics for granted, without expressly quantifying something that's otherwise greek to me (get it?...actually I do understand the greeks, they just seem like an unnecessary intermediary to me)
So, for the sake of my understanding equally to others, what assumption is second nature to me that's not inherently obvious? Because I can find disproofs to my original statement quite easily, but not without looking at a plainly stupid trade...(and incidentally, plainly stupid even by my logic when I was on the losing side that gave rise to the lesson underlying my original statement).
I suck royally at predicting the market--I'm *ok enough* at managing risk. I do make regular profits. So, for the sake of others (and myself), collaboration on identifying the difference in opinion (if it exists) might be a bit more helpful...
