Citigroup's profit jumped 40% and beat Wall Street's estimates on Tuesday.

Its stock still closed down 5.6%.

The big banks kicked off earnings season and the reactions made very little sense if you only read the headlines. Citi earned $2.85 a share on $23.8 billion in revenue and fell 5.6% to $124.53. Wells Fargo beat on profit at $1.87 a share, but revenue came in at $21.87 billion against roughly $22.31 billion expected, and the stock dropped 3.1%. JPMorgan missed estimates for the first time in nearly three years ($5.57 a share against about $5.85 expected) and only slipped 0.8%.

Goldman Sachs was the real lesson. It blew past estimates with $17.01 a share, opened at $923 and traded as high as $930.88, then closed at $891.91, slightly down on the day. Anyone who chased that opening pop gave back more than 3% by the close. Meanwhile the S&P 500 barely moved, finishing at 7,805.45.

Jamie Dimon also put a number on the risk everyone is watching. With the 10-year Treasury yield around 5.2%, he said going from 5% to 6% "would be more painful than going from four to five," and that people need to be prepared for it, even though he isn't predicting it. September CPI lands today at 8:30 a.m. ET.

Before you trade around a big report:

1. Decide your plan before the number comes out. A beat or a miss doesn't tell you which way the stock goes.
2. Don't chase the opening gap. Wait for the first 30 minutes to show you whether the move holds.
3. Set your stop and your size ahead of time. Event days can swing 3% to 5% in a single stock even when the index sits still.

That's what TradeShield is for: a plan you set when you're calm that protects you when the headlines don't make sense.

Stay sharp out there.
