This must take into account the immediate fertilization, then subsequent failure of the egg where a woman doesn't even miss her regular period (no abortion going on there), as I've never seen any stats close to that, and from the friends and family that I have, miscarriages are rare — less than 10 %.

So traders may try to «catch the lows» if the S&P 500 drops to the 830 area again, but I would expect that subsequent failure into the 700's could send those same traders, as well as skittish investors, rushing to sell at any price. (hussmanfunds.com)
Each successful exercise of it actually increases the likelihood of subsequent failure if temptations come in quick succession (as they do, for instance, in shopping malls). (nwei.org)
