BC—buying climax, during which there are often marked increases in and price spread. The force of buying reaches a climax, with heavy or urgent buying by the public being filled by professional interests at prices near a top. A BC often coincides with a great report or other good news, since the large operators require huge demand from the public to sell their shares without depressing the stock price.
AR—automatic reaction. With intense buying substantially diminished after the BC and heavy supply continuing, an AR takes place. The low of this selloff helps define the lower boundary of the distribution TR .
ST—secondary test, in which price revisits the area of the BC to test the demand/supply balance at these price levels. For a top to be confirmed, supply must outweigh demand; and spread should thus decrease as price approaches the of the BC . An ST may take the form of an upthrust (UT), in which price moves above the resistance represented by the BC and possibly other STs before quickly reversing to close below resistance. After a UT, price often tests the lower boundary of the TR .
SOW—sign of weakness, observable as a down-move to (or slightly past) the lower boundary of the TR , usually occurring on increased spread and . The AR and the initial SOW(s) indicate a change of character in the price action of the stock: supply is now dominant.
UTAD—upthrust after distribution. A UTAD is the distributional counterpart to the spring and terminal shakeout in the accumulation TR . It occurs in the latter stages of the TR and provides a definitive test of new demand after a breakout above TR resistance.
LPSY—last point of supply. After testing support on a SOW, a feeble rally on narrow spread shows that the market is having considerable difficulty advancing. This inability to rally may be due to weak demand, substantial supply or both. LPSYs represent exhaustion of demand and the last waves of large operators’ distribution before markdown begins in earnest.
