Successful resellers do not just sell what they have; they sell what the market wants next. A Fishgoo spreadsheet for market analysis turns scattered observations into a data-driven forecasting system. You spot rising brands, fading styles, and pricing inflection points before the competition catches on.
Why Gut Feelings Fail in Reselling
Many resellers rely on intuition. They see one viral TikTok and over-invest in a style that dies two weeks later. Or they miss a slow-burning trend that dominates the next quarter because early signals were too quiet to notice. Without structured data collection, every purchase is a gamble dressed up as instinct.
A market analysis spreadsheet inside your Fishgoo system changes the game. It aggregates demand signals from multiple sources, scores trend momentum, and highlights inventory categories worth increasing or decreasing. You stop chasing hype and start forecasting with confidence.
Market Analysis Tracker Columns
| Column | Purpose | Data Source |
|---|---|---|
| Category / Style | Trend being tracked | Manual entry |
| Platform Signals | Mentions per week | TikTok, IG, X |
| Search Volume | Relative interest | Google Trends |
| Marketplace Prices | Avg resale price | Grailed, StockX |
| Sell-Through Rate | % listed that sell in 30 days | Platform data |
| Trend Score (1-10) | Weighted composite | Formula |
| Action | Buy / Hold / Avoid | Manual decision |
| Date Logged | When trend noted | Auto timestamp |
Building the Trend Score Formula
Create a composite score by weighting the signals that matter most to your niche. A simple but effective formula:
Trend Score = (Platform Signals / 100 * 3) + (Search Volume Index / 10 * 3) + (Sell-Through Rate * 2) + (Price Growth % * 2)
Normalize each input to a 1-10 scale, then weight according to your confidence in the data source. Over time, adjust weights as you learn which signals predict actual sales in your inventory.

Market Analysis Best Practices
- Update your market sheet weekly, not daily. Daily noise creates false signals.
- Track both rising and falling trends. Avoiding a dying category is as valuable as catching a rising one.
- Cross-reference social signals with actual marketplace sell-through. Viral does not always mean profitable.
- Archive outdated trends monthly to keep the active view focused and fast.
Frequently Asked Questions
How early can I spot a trend?
Most micro-trends show up on TikTok 2-4 weeks before hitting resale marketplaces. Niche Reddit communities sometimes surface styles even earlier.
Should I trust AI trend prediction tools?
Use them as one input among many. No tool replaces your own sales data and on-the-ground observation of what buyers actually purchase.
Conclusion
Market analysis is the difference between reactive and predictive reselling. A Fishgoo spreadsheet aggregating platform signals, search trends, and sell-through data gives you a measurable edge. You buy before prices spike, avoid dying trends, and stock what the market actually wants.
