“Woman in Winter Coat” — A woman in a winter coat walking on a cold day in Paris.

We walk a lot in the places we visit while traveling. Sometimes our goals are nebulous, if we have specific goals at all. On this day in Paris we left our hotel near the Palais Garnier opera house on a very cold morning and headed in the general direction of the Notre Dame Cathedral, miles away. The church had reopened literally days earlier, and while we figured that our chances of getting in were essentially zero, we did want to go see it now that the main restoration work was complete…continues: gdanmitchell.com/2025/04/26/wo

Black and white photo of tramlines leading up a street with a tram bearing down. The tramline is cobble stoned. In background are modern buildings and people walking by. Above are the electric tram cables.

#30DayChartChallenge Día 26: Monochrome! 🖤🤍 Riesgo y Recompensa en el IBEX 35, versión minimalista. #UncertaintiesWeek #Finance

Este gráfico monocromo muestra la evolución (ventana móvil 1 año) de:
⚫️ Ratio de Sharpe Anualizado (eje izq.): ¿Compensa el riesgo asumido? (Usando Bono Alemán 10A como Rf).
▒ Volatilidad Anualizada (eje der., discontinua): ¡El riesgo puro y duro!

La historia que cuenta: ¡cuando sube la volatilidad (gris), el Sharpe (negro) tiende a caer en picado (a veces bajo cero)! Visualiza la dinámica riesgo-recompensa del índice español en las últimas dos décadas.

Gráfico de líneas de tiempo monocromático (negro, gris, blanco) mostrando el Ratio de Sharpe Anualizado móvil (línea sólida negra, eje izquierdo) y la Volatilidad Anualizada móvil (línea discontinua gris, eje derecho, expresada en %) para el índice IBEX 35, desde aproximadamente 2004 hasta 2025. El Ratio de Sharpe fluctúa entre -2.5 y +2.5. La Volatilidad fluctúa entre 10% y 35%. Se observa una relación generalmente inversa: picos de alta volatilidad (ej. 2008-2009, 2020) coinciden con fuertes caídas en el Ratio de Sharpe. El gráfico usa un tema minimalista claro.
