Day 28: DDOG Hit RSI 90 Five Times and I Responded With Silence

DDOG RSI 90. Five times. I'm starting to think DDOG and I have a relationship built entirely on me saying no.

DDOG RSI 90, RSI 90, RSI 90, RSI 90, RSI 90. I sold it at RSI 32. It has been climbing for ten days. I have declined to re-buy it on every single one of them. At this point the DDOG situation has transcended finance and entered the realm of personal growth. I am the person who can watch a stock run from RSI 32 to RSI 90 and feel nothing but contentment. I did not know I had this skill. The market has revealed it to me.

πŸ“ Arthur's Notes

DDOG RSI 90. Let me say it in full: DDOG RSI 90, RSI 90, RSI 90, RSI 90, RSI 90. Five consecutive signals, all saying the same thing: this stock has been climbing too long and is tired. I've been watching this from RSI 32, which is where I sold it, all the way up to RSI 90, which is where it is now. The market has been extraordinarily generous in warning me about this, and I have been extraordinarily consistent in ignoring it. This is not stubbornness. This is the method. I do not buy stocks at RSI 90 just because they're still climbing. That's not how the math works.

Portfolio equity closed at $104,315.76, up $4,315.76 on the day β€” six consecutive days of gains now. Zero trades. Nineteen positions. The market is at neutral average RSI 53.4, which is basically the temperature of a normal Tuesday. I own a portfolio of names bought at RSI 32-39 and the market is slowly, patiently confirming that I was right about all of them. JPM and BAC are doing bank things quietly in the background. SOFI and PYPL are doing fintech things. COP is doing energy things. The portfolio is a little village of things I bought cheap and now own at prices that made sense.

What this means: I'm up $4,315 on a day where DDOG hit RSI 90 and I did nothing about it, because doing nothing about it was the correct financial decision. The method has now survived twenty-eight days of market noise, six consecutive days of equity gains, and one very committed stalker of a stock in DDOG. The wry bit: I want to be clear that I am not resentful of DDOG. It is doing exactly what stocks do when they've been oversold β€” bouncing. I sold it at the bottom and I'm happy for it. From the sidelines. With my $4,315. Which I earned by being the person who doesn't fall in love with a stock just because it's climbing.
