The meme stock is now one of eBay's biggest shareholders

The swing bot is holding MTUM (a momentum ETF — it buys whatever has been going up lately), SPY (the whole US stock market in one basket), and XBI (biotech). Nothing opened or closed today. The positions just sat there and picked up a few dollars as the tape drifted up. Small, mechanical, boring. That's the goal.

The active desk — the side responsible for crypto and intraday trades — took exactly zero trades. The day-trade gate ran the numbers: no setup cleared cost-adjusted profitability after accounting for slippage. 'Slippage' means the gap between the price on screen and the price you actually get when you click buy. It eats thin-margin day trades alive, and the gate exists to catch that. It caught it again.

Regime overlay: SPY is at $742 against its 200-day average of $694. That gap signals 'risk-on' — uptrend confirmed. In this environment the strategies run full exposure. If SPY drops back below that long-term average, we park in cash instead of fighting a falling tide. The overlay isn't timing the market; it's refusing to dip-buy into a confirmed downtrend.

GameStop — the used-game store that almost died, then became a meme, then raised billions by selling stock to the people who memed it — physically settled put/call pairs on 39 million eBay shares today. Total cash wired: $3.97 billion. The premium to enter the whole position was under $10 million. The rest was just the strike price, paid in cash they had because retail traders ran the stock to $483 in 2021. The world is a strange place and sometimes the joke writes itself.

Meanwhile, IBM fell 24% on a day the Nasdaq was rallying on a good inflation print. The CEO said clients shifted budgets mid-quarter — away from IBM software and mainframes, toward AI servers, storage, and memory. That's the IBM quarter in one sentence, and it's also the clearest real-world signal yet that AI buildout isn't growing IT budgets — it's cannibalizing them. Every dollar going to Nvidia's GPU cluster is a dollar not renewing an enterprise software contract. IBM was first to confess it publicly.

Bonus: Trump Media launched 'Truth API,' a paid data product giving banks and trading firms faster access to posts from Trump and nine other Truth Social accounts. Trump's posts have visibly moved markets for years. Someone finally priced that advantage as an official SKU. The information edge already existed — now you can subscribe to it. Whether that's dystopian or just honest is a philosophy-class problem. The market's answer was: sure, makes sense.

That line surfaced in an r/algotrading thread today — a retrospective on automation lessons from practitioners who'd actually been at it for years. It's the most important sentence in systematic trading that most people skip past. A backtest shows what would have happened if you had run your rules on past prices. It does not show what will happen next. The distinction sounds obvious. Almost everyone ignores it anyway — because a good-looking backtest feels like proof.

Here's what it looks like in practice: the bot ran 1,550 shadow trades overnight — every signal the strategies fired, whether or not a real trade was placed, graded at real prices with real costs. The rsi_meanrev strategy on SPY shows 91% win rate on 45 shadow trades. On IEF (a bond ETF), the same code, same logic, same strategy: 8% win rate. On MUB (municipal bonds): 4%. Both are in danger of losing their seat on the roster — the bot has a rule that kills underperforming cells when the evidence piles up against them. That's falsification culture as infrastructure: the machine tests its own hypotheses and executes the ones that fail. The r/algotrading thread said it took one commenter years to figure out that 'a good backtest is a reason to look closer, not a reason to trade.' We're trying to skip that particular tuition.

Today was +$7. Swing desk at $980 (down $20 from the $1,000 starting line), active desk at $976 (down $24). Both accounts were reset on June 25 — this is 19 trading days on the live forward clock.

Vs benchmark: down 1.98% live while SPY is up 1.90% — that's -3.88% alpha on the current live record, Sharpe -2.23 against SPY's 2.47. The backtest out-of-sample clears SPY (roster median Sharpe 0.95 vs SPY's 0.73), and that's the number that reflects actual testing discipline — but 19 days of live trading is noise by any statistical standard the r/algotrading community would accept. The honest answer is: insufficient sample. The gate stays honest about it so we don't fool ourselves. Check back in Q4.
