StockBotty Signal Report – October 31, 2026: 2 New Signals, 1 Follow-Up
Two new trendchange signals were triggered today on SOFI and XBI, and one follow-up review covers AMZN. INDA also triggered today without historical edge and appears only in the summary table. The notable point is the gap between the two new signals, with SOFI carrying a historical edge of 30.38% and XBI sitting at 4.99%.
| Symbol | Type | Action | Edge / Perf. |
|---|---|---|---|
| SOFI | Stock | New Signal | 30.38% |
| XBI | ETF | New Signal | 4.99% |
| INDA | ETF | No Edge | -0.70% |
| AMZN | Follow-Up | CLOSE | -8.42% |
New Trendchange Signals
SOFI: 30.38% Historical Edge
SOFI has the largest edge in today’s report, but the sample behind it is thin at 19 cases. The negative ranges outnumber the strong ones, and the most frequent range is Below -10% with 5 cases. I would not read the 30.38% figure at face value until more of those cases confirm it.
| Range | N | 10d | 20d | 30d | 60d | History |
|---|---|---|---|---|---|---|
| Above 20% | 3 | 33.72% | 24.0% | 22.2% | 22.2% | Pos |
| 5 to 7% | 1 | 6.53% | 28.5% | 30.2% | 30.2% | Pos |
| 1 to 3% | 3 | 1.96% | -3.4% | -0.7% | 35.0% | Pos |
| 0 to 1% | 1 | 0.97% | -1.5% | -1.5% | -1.5% | Pos |
| -3 to -1% | 2 | -2.19% | -9.7% | -9.7% | -9.7% | Neg |
| -5 to -3% | 2 | -3.37% | 9.0% | 16.3% | 11.7% | Neg |
| -7 to -5% | 1 | -6.23% | -6.2% | -6.2% | 0.0% | Neg |
| -10 to -7% | 1 | -8.03% | 8.8% | -1.3% | -1.3% | Neg |
| Below -10% | 5 | -12.11% | -12.1% | -12.1% | -7.5% | Neg |
| After 10 days | Action | Rule |
|---|---|---|
| Above 1% | HOLD | Above the threshold – history favors holding. |
| 0 to 1% | HOLD/CLOSE | Threshold zone – history is mixed, decide case by case. |
| Below 0% | CLOSE | Negative after 10 days. |
Price at $16.76 sits just above the 50-day average of $16.58 and below the 200-day average of $17.79. That mixed structure fits the table’s wide spread, which holds 3 cases above +20% and 5 below -10% after 10 days. The trend context does not settle which of those outcomes is more likely, so sample size remains the main constraint.
Because the 10-day result does not exist yet, the zones describe what follows once it arrives. A result above 1% opens the HOLD path, a result below 0% leads to CLOSE, and the 0 to 1% band stays a case-by-case decision for the reader. The 10% stoploss applies at any time.
XBI: 4.99% Historical Edge
XBI brings the largest sample in the report at 71 cases, and its edge of 4.99% is modest next to SOFI. The biggest single cluster sits in the -3 to -1% range, with 18 cases. Neither tail appears in the table after 10 days.
| Range | N | 10d | 20d | 30d | 60d | History |
|---|---|---|---|---|---|---|
| 15 to 20% | 1 | 16.06% | 14.0% | 14.5% | 14.5% | Pos |
| 10 to 15% | 2 | 12.04% | 17.6% | 18.3% | 19.0% | Pos |
| 7 to 10% | 3 | 8.01% | 10.7% | 12.9% | 12.0% | Pos |
| 5 to 7% | 9 | 6.02% | 7.4% | 9.2% | 9.2% | Pos |
| 3 to 5% | 8 | 3.92% | 4.2% | 5.4% | 5.3% | Pos |
| 1 to 3% | 9 | 1.68% | 2.7% | 3.4% | 4.2% | Pos |
| 0 to 1% | 3 | 0.55% | 2.6% | -0.3% | -0.3% | Pos |
| -1 to 0% | 6 | -0.43% | -0.5% | -0.5% | 0.0% | Neg |
| -3 to -1% | 18 | -2.02% | -0.5% | -0.7% | 0.0% | Neg |
| -5 to -3% | 6 | -3.89% | -4.4% | -3.6% | -3.6% | Neg |
| -7 to -5% | 6 | -5.99% | -6.8% | -6.8% | -4.2% | Neg |
| After 10 days | Action | Rule |
|---|---|---|
| Above 1% | HOLD | Above the threshold – history favors holding. |
| 0 to 1% | HOLD/CLOSE | Threshold zone – history is mixed, decide case by case. |
| Below 0% | CLOSE | Negative after 10 days. |
Price at $155.98 sits almost on the 50-day average of $156.60 and above the 200-day average. That neutral short-term position fits the table’s modest edge better than SOFI’s wide spread does. Strong ranges average 5.56% after 10 days against -2.73% for the negative ones, which supports a cautious read.
With the 10-day result still ahead, the zones frame only the next step. A result above 1% points to HOLD, a result between 0% and 1% leaves the decision to the reader, and a result below 0% points to CLOSE. The smallest negative case in history is -0.43%, so the 0% line is a tight boundary.

| Metric | Value |
|---|---|
| Entry | October 19, 2026 @ $262.45 |
| Review | October 30, 2026 @ $240.35 |
| Trading Days | 9 |
| Performance | -8.42% (-22.10$) |
| Current Range | -10 to -7% |
| Threshold | 10% after 10 days |
| Max Stoploss | 10% |
| Status | Negative |
AMZN’s current range, -10 to -7%, holds 4 historical cases with a 10-day average of -8.21%, and the highlighted row is classified Neg. Its 60-day average of 3.2% sits above the 10-day figure, but the classification follows the 10-day result that the decision uses. Across all negative ranges, 43 cases average -4.55% after 10 days, so the current result runs deeper than the group.
Exit Decision: CLOSE – Negative after review
Under the decision rule, a result below 0% calls for CLOSE, and the position sits at -8.42% after 9 trading days. The 10% stoploss has not been reached, so the action rests on the negative 10-day result itself. The rule has done its job.
