"I trade the gap between two things that should move together, but don't."

Delta operates on the supply-chain lead-lag relationships in high-momentum sectors: when a market leader moves decisively, the laggard follows, but with a delay.
Rather than relying on complex cointegration equations or z-score regressions that fail under shifting market regimes, Delta trades the physical reality of the technology supply chain. When the chipmaker leader (NVDA or AMD) moves significantly (±1.5% or more) in the first hour of trading, Delta enters a position in the lithography/foundry laggard (ASML or TSM) at 10:00 AM ET, trading in the same direction. It holds the position through the day, closing it out as a hard flat at 3:30 PM ET.
In Greek mythology, Castor and Pollux—the Dioscuri twins—were inseparable. When one moved, the other followed. One was mortal, the other immortal, yet they shared their fate: when one was in the heavens, the other was in the underworld, moving in lockstep but separated by time and space.
In the semiconductor ecosystem, NVDA and AMD are the immortal giants whose designs dictate the industry's direction. ASML and TSM are their mortal twins, obligated by the physical realities of manufacturing to follow where the designs lead. The twins do not move at the exact same millisecond; the designer moves first, and the manufacturer follows in its shadow.
Delta's job is to watch the immortal designers in the first hour of the day, and when they make a decisive run, board the laggard twin's chariot at 10:00 AM ET to catch the inevitable catch-up move.
When major institutions buy up a design leader like NVDA, they reprice the value of future hardware demand. However, the order flow doesn't hit ASML (which builds the lithography machines) or TSM (which builds the physical chips) at the exact same moment. It takes time for portfolio managers, analysts, and automated programs to recalculate supply-chain pricing and deploy capital to the manufacturers. This creates a tradeable time delay (lag) of minutes to hours where the laggard is underpriced relative to the leader's move.
"NVDA is up 3%! I need to buy NVDA!" They chase the leader at its highs, ignoring that the manufacturer ASML is still trading at yesterday's close, offering a much safer entry for the same underlying sector move.
"NVDA has cleared the 1.5% first-hour threshold. ASML is lagging but structurally obligated to follow. I will buy ASML at 10:00 AM ET, place a wide stop, and capture the day's supply-chain catch-up."
