Our Relative Strength Engine is holding one quietly crowded position

SPY fell hard this week. Our open book held — but one name inside the table deserves a closer look.

The week at a glance

SPY dropped 1.37% this week. We made 2.57%. That's the kind of number that deserves an honest look — because the picture underneath it is messier than the headline suggests. Day 35 of the experiment. System return since inception: +2.6%. SPY over the same window: +1.9%. Cumulative alpha: +0.65%. We're ahead — but only modestly — and we've got 14 open positions, ten of them in the same stock. So let's talk about what's actually going on. Here's the full snapshot of everything open right now: | Ticker | Engine | Day | Entry | P&L | Alpha | |--------|--------|-----|-------|-----|-------| | SNOW | Relative Strength | 26 | $270.92 | +22.83% | +19.23% | | CORT | Relative Strength | 25 | $91.92 | +33.00% | +29.64% | | SLS | Relative Strength | 15 | $12.15 | +27.24% | +28.22% | | CRNX | Relative Strength | 17 | $83.93 | +0.91% | +1.43% | | CRNX | Relative Strength | 12 | $84.22 | +0.56% | +1.50% | | CRNX | Relative Strength | 11 | $84.26 | +0.51% | +1.14% | | CRNX | Relative Strength | 10 | $84.47 | +0.26% | +1.14% | | CRNX | Relative Strength | 9 | $84.53 | +0.19% | +1.75% | | CRNX | Relative Strength | 8 | $84.61 | +0.09% | +1.46% | | CRNX | Relative Strength | 5 | $84.70 | -0.01% | +0.89% | | CRNX | Relative Strength | 4 | $84.78 | -0.11% | +0.12% | | CRNX | Relative Strength | 3 | $84.76 | -0.08% | +0.35% | | CRNX | Relative Strength | 2 | $84.72 | -0.04% | -0.44% | | CRNX | Relative Strength | 1 | $84.74 | -0.06% | -0.06% | No closed trades this week. Zero. The win rate for closed trades is still 0-for-0 — not because we're losing, but because the system hasn't exited anything yet. Everything is still running.

Trades we closed this week

No closed trades means no post-mortems this week. That's actually worth sitting with for a moment. SNOW is up 22.8% from a July 27 entry. CORT is up 33% from July 28. SLS is up 27.2% from August 7. These are real moves — held open, not locked in. That's a deliberate choice the system is making, and it's the right one when a position keeps trending cleanly. The Relative Strength Engine isn't built to grab quick profits and step aside. It's built to stay in the chair as long as the stock keeps acting well. The trade-off is straightforward: open P&L isn't realized P&L. If SNOW reverses hard next week, that 22.8% shrinks fast. We know that. We're not pretending otherwise. Then there's CRNX — and we need to address it directly, because ten positions in one ticker looks strange in a table and it is strange. The Relative Strength Engine kept flagging CRNX daily because it kept qualifying on relative strength criteria. Each entry is treated as a separate signal. Entries started around $83.93 and have clustered tightly between $84.22 and $84.78 since. The stock hasn't moved meaningfully in either direction. The five most recent entries are all slightly negative on P&L — fractions of a percent, but still moving the wrong way. Is this a problem? Honestly, we're watching it closely. Ten entries in one name at nearly identical prices means real concentration. The Relative Strength Engine sees a qualifying stock; the position-sizing logic hasn't pushed back yet. That's a behavior worth flagging — and one we'll keep an eye on heading into next week.

What we tuned this week

This was a hold-and-monitor week, not a build week. No new setups were added or tuned. What's on our radar for next week: CRNX concentration. If the stock keeps drifting sideways or starts slipping, we'll be watching whether the engine continues adding entries or whether price action finally disqualifies it. At some point, a stock that stops moving stops qualifying — we just haven't crossed that threshold yet. SNOW, CORT, and SLS are the positions doing the heavy lifting. All three opened in late July or early August and have run well. None of them moved much this specific week — most of the weekly gain came from SPY falling while our open positions held their ground. That's a real form of alpha, even if it's a quieter one than a clean breakout.

What we're cautious about next week

Three things we're watching carefully heading into next week. First: concentration in CRNX. Fourteen open positions, ten of them the same ticker, entered within a few dollars of each other. If that stock moves against us sharply, the drag is real. It's not catastrophic at current sizing, but it's the single clearest risk on the board right now. Second: we still haven't closed a position. That's not inherently bad — nothing has hit its exit rules yet — but it means we're carrying unrealized gains in SNOW, CORT, and SLS that could still give ground. The system is designed to let winners run, and we trust that design, but 33 days without a realized exit is a long time. At some point, the market will test that patience. Third: SPY had a rough week and our open positions held up. Good. But it also means next week's tape matters more than usual. If the selling continues, we'll get a cleaner read on whether the relative strength in our holdings is structural — or just lagged.

Looking ahead to Monday

Thirty-five days in, we're ahead of SPY by about 0.65% on a cumulative basis. That's real, but it's thin. SNOW, CORT, and SLS are what's keeping this experiment in positive alpha territory — and everything depends on whether those positions continue to hold and eventually close profitably. Next week will tell us whether this past week's market weakness was a one-session blip or the beginning of something that tests our open book in a more serious way. I'm more curious than nervous about that answer — but I'd be lying if I said I wasn't keeping one eye on CRNX.
