Return chasing#
Week 4
Something in your field of view#
has gone up more than yours#
You opened with#
250 units of A at $40.00 = $10,000
fee = $5Four weeks later#
A = $44.00
250 × $44.00 = $11,000Up 10%. Fine.
Meanwhile#
B: $10.00 → $18.00Up 80%.
So you rotate#
sell A at bid $43.96 250 × $43.96 = $10,990
less fee $5
───────
$10,985
buy B at ask $18.00 $10,980 / $18 = 610 units
plus fee $5You also just paid the week 2 round trip again#
$20, for the privilege of changing your mind.
What was the evidence?#
One sentence. Write it now.
For most people it reduces to#
B went up more.#
Not that it#
sells more of something
costs less relative to what it earns
has customers who cannot easily leave
Recent performance is#
a real fact about the past
a weak claim about what happens next
Fill in the counterfactual#
Today. Not in April.
If I do nothing today, what happens?
For this example#
250 units of A, worth $11,000No forecast. No reasoning.
The position you would still hold, at a price you can check.
Carry it to week 12#
A = $46.00 B = $14.00
chose: 610 × $14.00 = $8,540
refused: 250 × $46.00 = $11,500
─────────
gap $2,960A rose 15%#
The market was not the problem.
On the day, that column is evidence#
Reconstructed in week 11, it is a story about yourself.
Nobody writes an unflattering one.
Do it today and you have an assignment#
Do it in April and you have an anecdote.
