About
A concentrated “old tech” stock strategy: roughly half stays in classic tech names, while the other half rotates into the 3 strongest performers from the group based on the past 60 days.
This strategy mixes two approaches.
About half the money stays in 7 long-time tech/industrial stocks all the time: Microsoft, Intel, AMD, Texas Instruments, HP, IBM, and GE.
The other half looks at 11 “old tech” stocks and picks the 3 that have been doing best over the last 60 days (about 2 months). It then puts that money into those 3 winners. So it combines a core group of old tech names with a simple “buy what’s been strongest lately” rule.
Two-sleeve approach: 7-core techs plus momentum in the top 3 of 11 legacy techs. Out-of-sample annualized return ~36.7% vs S&P ~20.9%, with positive alpha and strong risk-adjusted metrics.
