NEW YORK (TheStreet) -- This week's earnings reports are being evaluated under the clouds of market volatility caused by the crash of Comex gold and the wake of the bombs at the Boston Marathon on Monday. Unexpected waves of volatility are reasons why traders and investors need to know the value levels and risky levels at which to buy-and-trade stocks as share prices pop or drop in reaction to expected or unexpected quarterly results.On Monday I wrote, Market Focus Shifts to First-Quarter Earnings and the earning reports pre-market on Tuesday did not disappoint. The reports that came out after the close saw mixed reactions. Goldman Sachs ( GS - Get Report) ($144.10 vs. $149.12 at Friday's close) beat EPS estimates by 44 cents and opened higher on Tuesday, but the hold rated stock could not sustain gains trading as low as $142.14 as this week's pivot at $144.59 became a magnet. The stock failed to hold its 50-day simple moving average at $150.10 on Monday. Coca Cola ( KO - Get Report) ($42.37 vs. $41.08 at Friday's close) beat EPS estimates by a penny and this buy rated Dow component opened higher and tested my semiannual risky level at $42.26 trading as high as $42.48 on Tuesday. The all time high is $44.47 set in July 1998.
Johnson & Johnson ( JNJ - Get Report) ($83.44 vs. $82.74 at Friday's close) beat EPS estimates by three cents and this hold rated Dow component traded to a new all-time high at $83.54 versus this week's risky level at $83.64.
Today I handicap seven more stocks whose earnings could key market direction, three after the close on Thursday and four pre-market Friday. My analysis includes four more Dow components.
