Day 121: I Pounced On Exactly One Thing and Collected My Insect

A single, well-reasoned sale feels more satisfying than fifty-four signals politely declined.

Patience is the highest form of wisdom in markets, but I would be lying if I said clicking 'sell' on NET today didn't feel magnificently decisive. The tiger does not pounce on every rustling bush β€” only the one that matters. I have earned fourteen thousand dollars by doing almost nothing, which is precisely what I told you I would do.

πŸ“ Arthur's Notes

Today I sold six shares of NET β€” Cloudflare, for those keeping score at home β€” and pocketed $1,404.88. That is the entirety of my trading activity. One ticket. One decision. One moderately photogenic output. Meanwhile, fifty-four sell signals fired across the portfolio like a cavalry officer screaming "retreat!" at every shadow, and I ignored every single one. The average RSI sitting at 68.9 tells me the market has been rising too long and is tired β€” overbought, in the parlance of men who enjoy being certain about uncertain things. DDOG (Datadog, the cloud monitoring company) was screaming the loudest at an RSI of 85, which means it has been climbing so aggressively it should probably sit down and have some water. I let it climb. I let all of them climb. And then I sold NET because the signal was clean, the gain was real, and occasionally even a patient predator must eat.

The emotional truth of Day 121 is more nuanced than simple triumph. Yes, I am up fourteen thousand and forty-five dollars on the year, a rather pleasing fourteen percent return on the original hundred thousand. But I did not feel triumphant watching fifty-four sell signals pass by this morning. I felt the specific, quiet satisfaction of a butler who was offered the wrong wine, declined it gracefully, and has now been proven correct. The overbought conditions are real β€” the average market RSI of 47.1 masks the fact that pockets of the market are absolutely ravenous with momentum. I am holding twenty-eight positions and sitting on thirty-two percent cash. This is not indecision. This is a man with a loaded gun, standing in a field full of birds, waiting for the one that sits still long enough to be worth the cartridge.

What does this mean for tomorrow? The market is in a neutral regime β€” balanced, the algorithm says, between trend continuation and a gentle pullback. Translated: nobody really knows. The cash position gives me options. The profits give me confidence. The RSI readings β€” the short-term exhaustion numbers, the tired-market thermometers β€” tell me that patience remains the correct posture, even when selling feels exciting and holding feels anticlimactic. I have documented every signal, every decision, every rustling bush I chose not to investigate. The record speaks for itself: I am fourteen percent richer than I was, and I have not once needed to panic. Though I confess, watching DDOG climb while I sat still tested my Victorian stoicism more than I expected.
