NEW YORK (TheStreet) -- This week's biggest post-earnings winner is Nabors Industries (NBR), which surged 21.7% from its close last Friday on its better-than-expected earnings report. The oil and gas drilling and exploration company also benefited from analysts' upgrades.
Two Internet commerce companies reported their quarterly results after the closing bell on Thursday with two opposite post-earnings reactions. Priceline.com (PCLN) handily beat analysts' earnings per share estimates and opened this morning with a gain of 4.2% from its Wednesday close. The stock also set an all-time intraday high at $1,333.12 this morning.

The stock set a multiyear intraday high at $52.72 on Wednesday, testing my monthly risky level at $52.58 where buy-and-trade investors could have booked a nice gain. The weekly chart is now positive with its five-week modified moving average at $47.13 and its 200-week simple moving average at $37.39. My semiannual value pivots are at $48.43 and $44.99 with my monthly pivot at $52.58 and annual risky level at $57.49.
Groupon ($8.96 at today's open vs. $10.02 on Wednesday) reported a loss of 12 cents a share after-hours on Thursday.
The stock gapped below its 200-day SMA at $9.72 this morning and could challenge its Dec. 2 intraday low at $8.40. The weekly chart provided a warning with a negative configuration with its five-week MMA at $10.32.
