About
L.A. Molina started in physics — Harvard, and a habit of mind that never left: treat the world as a system to be modeled, measured, and questioned. He brought that lens to markets more than 30 years ago and never put it down.
He learned risk where the stakes are highest. As Global Head of Commodities Index Trading at Merrill Lynch, he scaled a platform past $10 billion in assets. As a Managing Director at Credit Suisse, he led a twenty-person trading team and helped build the trading and risk systems behind it. At DRW, he ran real-time VaR, exposure, and P&L analytics across multiple trading desks — and helped fuse physical and financial exposures into a single view of risk.
Energy is where exposure gets physical. At Talen Energy, as Director and Head of Quantitative Risk, he built the enterprise analytics platform behind trading, valuation, and portfolio risk. As Senior Director of the Middle Office at Delek Supply & Trading, he led the function that kept a refiner's trading honest — exposure, P&L, reconciliation, valuation — rebuilding its reporting stack in Python and SQL and cutting manual work by more than half.
He has always built the machinery, not just used it. Through his own consultancy, Escalar, he advised firms on trading infrastructure and risk analytics. And on his own time, he engineered a real-time desktop trading and risk application — for macOS and Windows — that values a portfolio across futures, stocks, and options tick by tick, computing VaR, CVaR, and stress scenarios as the market moves.
ScalarPhase is where that experience goes to work for others: advisory for firms with exposure, systems for teams that need real measurement, and education for anyone who wants markets taught properly — from first principles.
The name
In physics, almost everything comes down to a phase — the angle φ in the expression eiφ. It sounds abstract, but its effect is concrete: phases are what make waves interfere. When two quantum possibilities arrive "in phase," they reinforce each other; when they arrive out of phase, they cancel. That interference is the entire engine of quantum mechanics.
A "scalar" phase is simply the most basic kind — a single number rather than something more complicated. And it shows up everywhere:
So the name is a small thesis: beneath markets, risk, and uncertainty — as beneath everything else — reality is a sum over possibilities, weighted by phases, and what survives is where the phases agree.
Operating principles
No framework survives contact with an unmeasured exposure. The first job is always honest measurement — positions, Greeks, tails — before any opinion about what to do.
Most risk failures aren't math failures. They're failures to look at the tails honestly — and to build systems that force you to keep looking.
Advice that can't be implemented is entertainment. Engagements favor working systems and concrete procedures over slide decks.
