Period 17 Review: CANSLIM and Burry Post Career-Best Weeks as a Benchmark Surge Wipes Out the Journal's Last Cumulative Alpha
CANSLIM Rocket and Burry Value Screen post the best results of their histories at +7.34% and +7.03%, as a mining and metals rally lifts five of seven screens together. Quality Growth is the lone decliner at −2.59% — its third straight losing period — as SEZL collapses −23.74%. Both benchmarks post their strongest gains of the journal, erasing Quality Growth's cumulative alpha lead: for the first time, every screen now trails both the S&P 500 and NASDAQ cumulatively. Schloss Dividend overtakes Quality Growth atop the cumulative standings, and the 9.93-point spread between best and worst screen is the widest the journal has recorded.

Period 16 Review: Piotroski's GLOB-Powered Surge Vaults It from Last to First as Quality Growth's Slide Extends
Piotroski F-Score rockets from last place to the week's best screen at +2.37%, powered almost entirely by GLOB's +16.93% reversal — a stock that was falling just one period earlier. Quality Growth posts its second straight worst-place finish at −2.94%, this time dragged down by FICO's −9.25% rather than the SEZL and DAVE swings that sank it last period. Both benchmarks close positive for the first time in three periods, yet only two of seven screens beat them. The cumulative standings hold their exact Period 15 order for the first time in months, even as CANSLIM Rocket reverses to negative on a second straight MU whipsaw.

Period 15 Review: Magic Formula's Mining Rebound Powers a Stunning Turnaround as Quality Growth Posts Its Worst Period Yet
Magic Formula rockets from the journal's worst-ranked screen to the week's best at +4.17%, powered by the exact mining cluster — HMY, ORLA, CGAU, IAG — that caused its worst period just seven days earlier. Quality Growth craters to −3.46%, its own worst period on record, as DAVE reverses from +9.90% to −8.54% and newly added APP debuts at −7.67%. Five of seven screens close positive, up from three last period, even as both benchmarks fall again. Magic Formula's surge vaults it past Piotroski F-Score in the cumulative standings, handing Piotroski last place for the first time in the journal.

Only three of seven screens close positive, breaking a three-period streak of narrowing spreads as the best-to-worst gap widens back to 6.81 points. Retention swings from six of seven screens at 100% last period to just two this time, as Lunch and CANSLIM churn the most.
