So the market had quite the Monday morning roller coaster. Nasdaq opened down 1.5%, S&P 500 dropped 1.2%, Dow fell 1.1% - all of it tied to that Iran military action over the weekend. Oil prices jumped over 6% from the geopolitical spike. Pretty wild stuff at the opening bell.

But here's the thing that actually matters: by lunchtime, everything had bounced back to flat. Nasdaq even climbed 0.4% at one point. Energy and industrials led the recovery, with tech following along. Consumer stocks stayed weak, but that's typical when risk sentiment shifts.

I think this is exactly where a lot of people get caught in the mental trap. You wake up, see a 1.5% drop, and your gut tells you the sky is falling. Then noon hits, markets stabilize, and suddenly it feels like nothing happened. Both reactions are basically noise.

The real question nobody asks during these moments is simpler: are the companies you own still solid? Are they still growing? Do they still deserve to be in your portfolio? For most people holding broad index exposure, the answer hasn't changed because one weekend of geopolitical tension doesn't alter the long-term fundamentals.

Wall Street's been through plenty of crises. Military actions, trade wars, rate shocks - you name it. And yet the indexes still grind higher over years and decades. That's not blind optimism, it's just what the data shows.

Days like Monday are tests of patience more than anything else. The market bounced back because the underlying economy and corporate earnings didn't suddenly break. Spoiler alert: they rarely do from a single geopolitical event.
