Why social chatter moves before the price does
Collectibles markets run on attention as much as fundamentals. A card can start trending in the community weeks before its price actually moves, as more people notice it, talk about it, and eventually decide to buy or sell. By the time that attention shows up as a price spike, the early window to act on it is already closing. Tracking the conversation itself, not just the price, is how you catch that window instead of reacting after it's gone.
Double Holo's sentiment tool aggregates that conversation from Reddit, where a large share of organized Pokemon card discussion happens across communities like r/PokeInvesting and r/pokemontcg, and scores it for volume and tone: how many mentions a card is getting, and whether the community sounds bullish or bearish about it. A card with rising mentions and a positive tone is showing real, early interest, not just visibility.
Sentiment is a leading indicator, not a substitute for price. It complements Pokemon card price history rather than replacing it: sentiment tells you attention is building, while price history tells you whether the market has actually acted on it yet. Reading both together, rather than either alone, is what separates a card that's genuinely heating up from one that's just getting talked about.
Sentiment can also be noisy. A single viral post or a spike in unrelated chatter, like a reprint rumor or a set announcement, can move the mention count without reflecting real buying interest. That's why Double Holo shows the underlying posts behind every score instead of just a number, so you can judge the hype in context rather than trusting it blindly.
