Submitted by Tyler Durden on 05/26/2012 - 12:10 Capital Markets Central Banks ETC NASDAQ New Normal Reality

Back on March 27, following the epic disappointment that was the BATS IPO, we presented a detailed forensic analysis courtesy of Nanex, which demonstrated step by step how a Nasdaq-borne algo may have been the culprit shattering BATS' hopes of ever going public. Fast forward two months later to the most anticipated IPO in recent history, in which FaceBook's even more epic, if not quite as stark, implosion has set back the general public's faith in capital markets decades back. The irony, of course, is that FB didn't do anything that many weren't warning about: it simply plunged which would make perfect sense in a normal world. This in turn was the spark that provoked the public ire - had FB simply doubled since IPO day, nobody would care about what really happened on May 18. Alas, it didn't. And now the lawsuits come. The problem is we don't transact in a normal world, but one dominated by central banks and algorithms - which is why the most pressing question for those who grasp the real new normal is how come in a market as controlled and manipulated as the central bank-dominated venue we have now, was FB stock allowed to plunge? For what may be the actual definitive answer, as opposed to now trite philosophical ruminations on valuation, ethics, underwriter and shareholder greed, we once again go to Nanex, which has caught the perpetrator red handed once again... As Nanex' Eric Hunsader tells us: "Turns out just before Nasdaq's quote crossed and became non-firm, one copy of the same quote (crossed) was marked regular, and I think that caused other algos to react and immediately sell off the stock. When that crossed quote from nasdaq appears, bid prices from other exchanges suddenly evaporate and that causes the NBBO spread to explode from 1 cent to 70+cents in 1/10th of a second! Nasdaq's quote started doing this when the stock approached 42.99 -- that effectively prevented the stock from going higher (a few spurious trades right at the open came from BATS for 44 ~ 45 etc, before Nq's quote was in play). So these stupid Algos effectively short circuited the stock for Facebooks IPO! Unreal."

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
