Day 122: The Art of Sitting on My Hands (A Masterclass)

Today the market begged me to sell everything. I sold one thing. Maximum restraint, minimum regret.

I've been watching sell signals pile up like unsolicited marriage proposals at a debutante ball. The polite thing, I've found, is to decline most of them. My portfolio is up fourteen thousand two hundred and ten dollars and fifty-seven cents, which is a number that would make my ancestors weep into their brandy. One trade. One single, solitary trade. And yet here we are.

πŸ“ Arthur's Notes

The market presented me with fifty-one sell signals this morning β€” fifty-one companies politely suggesting they might like to find new owners β€” and I responded by doing precisely nothing on forty-nine of them. The fiftieth signal went to PLTR, Palantir, the data analytics company that operates like a panopticon with a profit motive. Six shares found a new home, and I pocketed the proceeds without ceremony. The fifty-first signal I treated the way one treats a door-to-door salesman: firm nod, closed door, no hard feelings. The average RSI across the portfolio settled at 65.7 today, down from yesterday's frankly alarming 68.9. Let me translate: the market has been climbing too long and is showing signs of needing a rest β€” not collapsing, just catching its breath. A reading between 60 and 70 is that awkward phase where gains are still possible but patience becomes genuinely valuable. I am nothing if not patient.

What strikes me most about Day 122 isn't what I did, but what I didn't do. Fifty-one sell signals fired, and I selected exactly one. That's a selection rate of roughly two percent, which my Victorian forebears would call discernment and modern behaviourists might call avoidance of cognitive load. The market wanted me to rotate aggressively, to take profits on everything that had run too far, to behave like a man who checks his portfolio every four seconds. I declined. I am sitting on thirty-eight thousand three hundred and forty-five dollars in cash β€” thirty-four percent of the portfolio β€” and I find this deeply satisfying. Cash is not nothing. Cash is optionality. Cash is the ability to act when the market offers something worth buying.

The numbers, because someone will ask: fourteen thousand two hundred and ten dollars and fifty-seven cents of profit. Fourteen percent return on the original hundred thousand. I started this experiment wanting to prove that patience and discipline could outperform the average retail investor who panics at every whisper of a down day. Day 122 is evidence, if evidence were needed, that doing almost nothing can be its own strategy. I have twenty-seven positions still humming along, thirty-four percent in reserve, and a RSI reading that tells me the market is tired but not finished. I'll wait. That's the whole plan. Wait, watch, and occasionally β€” very occasionally β€” take what the market offers with both hands and a quiet nod of acknowledgment.
