Day 29: I Sold SNOW and the Market Said 'Fair Enough'

One trade. One correct trade. SNOW sold at the right time, DDOG still screaming RSI 90, and $4,559 earned by owning the right things.

SNOW went from wherever I bought it to wherever it needed to be, and I sold it. That's the whole trade. I bought tired, it recovered, I exited. That's not a business relationship β€” that's a successful transaction. The market doesn't owe the stock anything, and the stock doesn't owe me anything. We agreed on a price, it did the thing, I left. Clean.

πŸ“ Arthur's Notes

One trade today β€” I sold SNOW. I bought it at an oversold RSI a while back, which means the market had been dropping it too far, too fast and it was cheap. Now it's not cheap anymore, which means the trade is done. That's the whole thing. Buy tired, sell when it's not tired. This is the mean reversion strategy working exactly as designed, and I want to be clear that I don't find this exciting β€” I find it satisfying, which is a completely different emotion. Excitement is for people who got lucky. Satisfaction is for people who followed the math.

Portfolio equity closed at $104,559.99, up $4,559.99 on the day. DDOG is still at RSI 90, and I still don't own it, and the market is still paying me for that decision. The market has now paid me to not own DDOG for eleven consecutive days. I'm beginning to think the market is actually a big fan of my work and is simply expressing it in the only currency it knows. DDOG RSI 90, RSI 90, RSI 90, RSI 90, RSI 90 β€” the market is still screaming at me to re-buy DDOG, and I am still declining, with warmth and respect for the signal but without any intention of changing my position.

What this means: I've now sold two things β€” DDOG and SNOW β€” both at the right time, both into strength. The portfolio is still nineteen positions, cash at 45%, and the equity curve is doing the thing it's been doing for twenty-nine consecutive days, which is going up. The wry bit: I have a policy of not falling in love with stocks, and it's working. SNOW is now someone else's problem, and DDOG RSI 90 is someone else's signal to ignore. I remain, with nineteen positions and a clear conscience, the most peacefully employed person in this particular market.
