Been listening to @sethstephensdavidovitz and wanted to come up with some testable hypotheses (if/then statements) regarding Google trends research and stocks. Again these are hypothesis statements (meant to be tested and proven right or wrong), not what I'm stating as fact.
1. If there is a significant boost in a search for a particular stock, then there is likely a short term trend happening.
Meme stocks aside, perhaps externally/pump driven stocks will have more searches, as opposed to "organic" growth stocks.
2. If a search for a particular stock is paired with "Reddit," then it will have a higher volume of trades from non-institutional investors.
3. If a stock is trending in New York then it will likely have significantly larger price movement in the following days compared to any other state.
4. If a state has an increased search for porn, then their search for "stock tips" will also increase.
5. If a particular musical artist tops the search trends, then the publicly traded company associated with them will see a small increase in volume.
6. If searches for the term "recession" increase by more than 20% then overall stock prices will fall.
7. If Warren Buffett mentions a company name in the media, searches for that company will drastically increase.
8. If terms tied to DISNEY and ESPN are trending, then the stock price of Disney will have a near term boost.
9. If a company has an increase in searches with "negative" words, then it's stock price will likely decline near term.
10. If a generic search for "online gambling" increases, then the company with the most digital ad spend, or at the top of searches will have a boost in users for the next quarter.
