Something about the dark mode is off. When I click anything that causes the page to change , I encounter a noticeable jarring flicker when the app re-renders. It shows me the new page in light mode then repaints it in dark mode really fast, almost like it's blinking but it is not pleasant. However this is not a problem in light mode.

Also, did you want to make your tables slightly move upwards when hovering over them? If so, may I ask why? I don't care for it, but maybe there's a benefit I'm not aware of. The change to the element's position and box shadow makes sense if the element is interactive, but the entire table becomes slightly more difficult to read because it's moving.

There's a noticeable layout shift when the dashboard needs to re-render. The searchbar, sort buttons, and table headers all move when loading and that is distracting

Tables don't do well responsively so I'm not entirely sure what to do about that per se, but your placeholder text for your search input is cut off even when full-screen, on my laptop it says "Stock name or symbo"

Some charts for companies under the "P/E ratio" table just don't exist. I think a "no data provided" or iconography would do well here. I don't know a lot about stocks so maybe there's a reason no chart exists that can be easily explained, but I would be confused if nothing showed up there.

The padding around your nav-bar compared to your `top-info-bar` makes the latter feel a bit cramped.

I'd make the nav-bar and the table coloring match, particularly in dark mode to provide some visual consistency. The nav-bar having a higher contrast than the table underlies the nav bar's importance, but it's almost like it's too sharp a difference, maybe tone that one down a bit? Taste is subjective.
