Market internals tell you more than headlines ever will.

Yesterday's session showed rotation under the surface—some sectors catching momentum while others gave back gains. Month-to-date and year-to-date numbers reveal which themes still have legs and which are starting to tire.

Pay attention to what's working and what's not. Breadth matters. When leadership narrows, it's usually a warning. When it broadens, it's often the beginning of something healthier.

Don't chase what moved yesterday. Watch what's quietly building strength over weeks and months. That's where the real signal lives.
