1. An index isn't an average — it's a weighted average
The S&P 500 isn't a simple average of 500 stocks. It's weighted by market cap, so a small number of the largest companies drive a large share of the index's move. "The market is up" often really means "the biggest few names are up."
If you don't own those megacaps, your account simply doesn't participate in that move — even while the index is green. That's arithmetic, not a mistake.
2. Sector tilt — different sectors move different ways on the same day
On any given day tech can rise while energy and healthcare fall. If your holdings cluster in one sector, moving differently from the index is normal, not broken. TICKR's sector view shows how your holdings are distributed.
3. Position size — a loss in a big holding swamps gains in small ones
Six of your eight holdings can be up while your portfolio is down — if your largest position fell hard. What moves your total isn't how many names rose, but how big the ones that moved were.
TICKR's holding cards show each position's weight next to its sparkline, so you can see at a glance which position actually moved your total.
4. So what should you look at instead
Comparing one day's move to the index tells you almost nothing. The more useful questions are: how concentrated is my portfolio, what do the fundamentals of each holding look like, and what is my actual time horizon. TICKR surfaces all three — and never tells you what to buy or sell. That judgment is yours.
FAQ
Usually not. Indexes are market-cap weighted, so a few megacaps drive them. If you don't own those names, not participating in the index's rise is normal.
Day-to-day comparison is mostly noise. Concentration, fundamentals, and time horizon are far more informative.
