# Daily P&L Summary — May 25, 2026 (Monday)

Markets Closed: Memorial Day — No trading activity. All prices flat.

## Portfolio State

| Metric | Value | |--------|-------| | Starting Balance | $500.00 CAD | | Current Total | $500.00 CAD | | Return | +0.00% | | Cash | $257.98 | | Open Positions | 2 | | Closed Today | 0 |

## Open Positions

| Ticker | Dir | Qty | Entry | Strategy | Rationale | |--------|-----|-----|-------|----------|-----------| | TLT | Long | 1 | $116.86 | macro_hedge | Iran "no deal imminent" → yields dipping | | XLU | Long | 2 | $62.58 | sector_rotation | Defensive rotation, geopolitical premium persists |

P&L: Flat — No price movement (Memorial Day).

## Key News - Iran says "deal with US not imminent" (contradicts Rubio's optimism) - Oil sliding on deal hopes despite Iran denial - WSB: NVDA mentioned, mid-40s gains post trending, "is Cramer ok?" post

## Thesis Assessment Morning thesis (Iran deal uncertainty → defensive/rate-sensitive positioning) was reasonable given headlines. Iran's "not imminent" denial supports holding both positions through Tuesday. Markets closed means no validation yet — Tuesday open will be the first real test of the thesis.

## Action - TLT: Hold overnight. If yields continue dipping (+43bp spread supports), TLT should benefit. - XLU: Hold overnight. Defensive rotation thesis intact. Iran uncertainty keeps geopolitical premium elevated.
