Overview

Four verified signals issued on January 9, 2026

This case study records four distinct signals published with timestamps across SPY, INTC, DUOL, and RGC. The goal is verification: each call is framed by the level, the date, and the market structure at the time of the signal.

Key signals at a glance

  • SPY: sold 70% at all-time highs $695
  • INTC: entry 18.70 → exit 45.4 (~+140%)
  • DUOL: 540 → 178 (~-67%) after breakdown
  • RGC: profit-taking signal at $65, price target $63

SPY — Sold 70% at All-Time Highs

The SPY signal reduced exposure by 70% into all-time highs around 695, emphasizing capital protection over incremental upside. The broader context references long-term accumulation during 2009 and 2020, plus a documented decision to double down near SPY $500 before the highs.

  • Signal type: risk reduction (sell 70% of exposure)
  • Level referenced: ~695 at the highs
  • Historical context: 2009 / 2020 accumulation, doubled near SPY $500

INTC — Exit 45–48 After Entry at 18.70

Intel was accumulated at 18.70 and sold into the 45–48 target zone. That move represents approximately +140% from the entry, showing the system's focus on predefined exits rather than narrative-driven extensions.

  • Entry: 18.70
  • Exit range: 45–48
  • Approximate move: +140%

DUOL — Breakdown From 540 to 178

Duolingo triggered a breakdown signal near 540 that preceded a slide to 178, a ~67% decline. The signal was issued before the larger selloff, with verification based on the recorded timestamps. For added context, read Duolingo at $540 = Zoom Video at $560: Algorithm Creator Exits Before the Crash.

  • Signal type: sell and short
  • Levels: 540 → 178
  • Approximate drawdown: -67%

RGC — Profit-Taking Signal at $65

Alex Vieira issued a profit-taking signal on Regencell Biosciences RGC, when its price printed $65 with a target price of 63, representing a 630% surge from entry price; within hours RGC price plunged $20 per share, the verification focus here is on the timestamped signal and stated targets rather than retroactive calculations.

  • Profit-taking signal: $65 (Jan 8)
  • Target Price: $63
  • Outcome: 630%+ surge

Verification Standard

Each signal was published with timestamps before the corresponding price move. The verification standard is simple: signal first, market response after.

  • Public timestamps across market channels
  • Signals issued before the move, not after
  • Price action confirms the outcome
