I found today’s Chart of the Day by using Barchart’s powerful screening functions to sort for stocks with the highest technical buy signals; superior current momentum in both strength and direction, a Weighted Alpha above 50+, and a 60-month beta above 1.5. I then used Barchart’s Flipcharts feature to review the charts for consistent price appreciation. SLS checks those boxes. The Trend Seeker issued a new “Buy” signal on May 13.
