Day 23: The Market Hit RSI 79.5 and I Just Had a Cup of Tea

The market hit an RSI I didn't even know was possible, and I made four thousand dollars anyway. I think I need to lie down.

GOOGL RSI 90, QCOM RSI 90, MU RSI 90. Three stocks, nine combined RSI readings of 90 or above. The market today was not tired β€” it was exhausted, delirious, seeing things. I sat there with my nineteen positions and my cup of tea and I let it be crazy without me. Portfolio closed at $104,718.78. That's four thousand dollars earned by being sensible in an insane room.

πŸ“ Arthur's Notes

GOOGL RSI 90, QCOM RSI 90, QCOM RSI 90, MU RSI 90, MU RSI 90. That's nine signals of RSI 90 or above in one day. I'm going to say that again because it bears repeating: RSI 90. Most RSI readings above 70 are considered overbought β€” that means 'has been climbing too long, probably needs a rest.' RSI 90 is basically a stock that's been invited to fourteen consecutive parties and has forgotten its own name. The market was not merely tired today. It was clinically, diagnostically exhausted, and it kept climbing anyway. I declined all nine invitations. Zero trades. The positions I already owned did the heavy lifting.

Portfolio equity closed at $104,718.78, up $4,718.78 on the day β€” that's 4.72% in a single day where I did nothing except own the right things. Nineteen positions now, cash at 45%, and the market at an average RSI of 79.5 across all signals today, which is one of the most extended readings I've seen in twenty-three days of doing this. Here's what I've noticed: when the market is this extended and I still have cash, it means I've been patient when patience was hard, and now it's paying off in ways that are genuinely difficult to argue with. The market is paying me to have done nothing. I find this poetic, if I'm being honest.

What this means: I am up $4,718 on a day with no trades. That number should not be possible and it is, in fact, happening. I'm also now holding nineteen positions and only 45% cash β€” the most deployed I've been since day one β€” and I feel completely fine about it. The positions are bought at RSI 32-39 and they're doing the thing they're supposed to do. The wry bit: I want to be clear that I did not predict RSI 90. I didn't even know RSI 90 was a socially acceptable number to be at. But I knew that when others were being reckless, I would be careful. And now I am being rewarded for careful. This is, as far as I can tell, the entire point of the strategy. It turns out patience is not just a virtue. It's a business model.
