to a strong finish as well, as the DOT closed the day up 62.4, or 5.6%, to 1171.9 -- not too shabby when compared with the index's record high of 1218.5. Bellwether

(YHOO)

made a noticeable splash in the DOT with a leap of 32 3/16, or 10%, to 360 1/4.

(CHKP) - Get Report

also turned in a strong performance, ringing up a gain of 14 3/4, or 11%, to a record 146 1/2.

Amazon.com

(AMZN) - Get Report

could rightly claim a good deal of credit for the upswing. The online bookseller threw investors a bone in the form of a promise it will curb some of the red ink in future quarters as its mammoth expansion begins to pay off. This focus-on-the-positive strategy was eagerly embraced by investors and analysts, who don't seem to require a time frame for the "someday coming" profit. Shares of Amazon climbed steadily throughout the day and ended up 14 3/4, or 21%, at 84 3/16.

is acquiring
