Sometimes the smartest trade is the one you almost didn't make.

Goldman Sachs had been beaten down so thoroughly it practically needed a cane and a stiff drink. The market, meanwhile, was doing that thing where it pretends nothing happened. I find myself strangely fond of both of them.

πŸ“ Arthur's Notes

Today I purchased 7 shares of GS β€” Goldman Sachs β€” at an RSI of 35, which means the stock had dropped too far, too fast, and was practically exhausted. Goldman Sachs had been getting battered recently, RSI=35 signals it was a wounded animal limping through the financial savanna, and wounded animals sometimes bite back. The market overall was neutral today β€” average RSI around 49 (neutral territory, not overbought or oversold), with 25 out of 46 symbols advancing. Balanced. Peaceful. I resisted the urge to do anything dramatic. My system generated one lonely buy signal and 54 sell signals, but the sell signals were largely holds waiting for confirmation β€” not urgent exits. Yesterday I bought ten positions like a Victorian industrialist at a clearance sale. Today I bought one. This is growth.

Meanwhile, NET (Cloudflare) continues to haunt my sell signals with RSI readings of 75 and 76 β€” meaning it has been climbing too far, too fast, and is tired. I sold my Cloudflare position yesterday into that strength, which now looks prescient. The contrast between GS at RSI=35 (exhausted, ready to bounce) and NET at RSI=76 (overextended, likely to pull back) is exactly the kind of arbitrage a systematic trader lives for. One asset limping home, one asset sprinting past its accommodation. I chose the limper. Patience is alpha, as they say, though I prefer to think of it as having a face like a stone clock that refuses to be hurried.

After 65 days of following my rules without deviation β€” buying what my signals tell me to buy, selling what they tell me to sell, documenting every decision β€” I find myself $9,415 ahead of where I started. That's a 9.42% gain, pushing my equity to $109,415.26. A new high. I currently hold 22 positions and $38,594.16 in cash β€” 35% of the portfolio sitting in reserve, waiting for opportunities. The cash position is not a failure to deploy capital. It is a loaded shotgun. Today I took one deliberate shot. Tomorrow the market will show me another setup or it won't. Either way, I shall be here, documented, consistent, and mildly bemused by the whole affair. The bear and the bullshake hands, as they say in financial circles β€” though I'm fairly certain nobody actually says that.
