Panic

Profit Taking

By this time, the smart money – heeding the warning signs – is generally selling out positions and taking profits. But estimating the exact time when a bubble is due to collapse can be a difficult exercise and extremely hazardous to one's financial health because, as John Maynard Keynes put it, "the markets can stay irrational longer than you can stay solvent." Note that it only takes a relatively minor event to prick a bubble, but once it is pricked, the bubble cannot "inflate" again.

In the panic stage, asset prices reverse course and descend as rapidly as they had ascended. Investors and speculators, faced with margin calls and plunging values of their holdings, now want to liquidate them at any price. As supply overwhelms demand, asset prices slide sharply. One of the most vivid examples of global panic in financial markets occurred in October 2008, weeks after Lehman Brothers declared bankruptcy and Fannie Mae, Freddie Mac and AIG almost collapsed. The S&P 500 plunged almost 17% that month, its ninth-worst monthly performance. In that single month, global equity markets lost a staggering $9.3 trillion of 22% of their combined market capitalization.
