"CFspark" Project

Tom Kelleher
8/14/2006 		This is my implementation of sparklines in a Flash client and a ColdFusion backend. The data source is the Yahoo.com csv files hosted at http://finance.yahoo.com. They provide a dynamic source of up to 5 years of daily trades. The live demo on the right side of this web page is a copy of a January 9, 2005 AP story about year-end earnings. The 3 embedded sparklines represent the most recent year's closing price for Alcoa Aluminum, Intel Inc. and Apple Computer. The story is frozen in time, but the sparklines are refreshed with the last 365 days of closing prices on every page reload. This builds on the sparkline concepts of Edward Tufte and the examples from James Byers and his Sparkline.org web site.

    Earnings May Decide if Rally Continues

    Dow component Alcoa Inc. traditionally kicks off earnings season as the first major company to report earnings. Looking at recent quarters, however, investors can be forgiven if they would prefer another high-profile company to go first. The aluminum company is slated to earn 41 cents per share for the fourth quarter, up from 37 cents from a year ago, when it reports Monday afternoon.

    Chip maker Intel Corp. which issued a very positive mid-quarter update last month, is a more likely candidate to surpass Wall Street profit forecasts when it reports its earnings after Tuesday session. The Dow component is expected to earn 31 cents per share, compared with 27 percent in the fourth quarter last year. Intel shares have slid steadily over the past year, falling 33.4 percent from their 2004 high of $34.24 on Jan. 8 to close Friday at $22.80.

    Apple Computer Inc. has seen its stock price climb in the opposite direction as Intel, rising steadily from a 2004 low of $21.79 on Feb. 4 to close Friday at $69.25 -- a 217.8 percent increase. Much of that can be attributed to the success of Apple's iPod music player, sales of which boomed this holiday season. Apple is expected to earn 46 cents per share when it reports on Wednesday, a big jump from the 16 cents per share it earned a year ago.
