Strategy #0000000109 · Investor behaviour and information diffusion
Investor attention and media coverage
Enter an attention-change threshold, neglected-stock return, spike-period move, later reversal and costs.
Sparse media coverage may raise information-acquisition frictions and coincide with higher expected returns. A sudden increase in attention proxies such as Google searches may create short-term retail buying pressure followed by reversal. The horizons differ, and attention measures, firm size and newsworthiness create biases.
No search, social or media data are connected; causality, realised holding periods and capacity are not estimated.
Three ways in
Understand the story. Then inspect the risk.
Start with a familiar situation, check the payoff, then test how the numbers change.
The idea · in two minutes
How do neglected-stock premia compare with the two return legs after an attention spike?

Investor attention and media coverage: read the record with its caveats.
The chart uses the published figures or explicitly labelled study inputs below. A historical index or model replay is not the same as an investor’s realised account return.

| Related strategy | Relationship | What changes | New cost or risk |
|---|---|---|---|
| Base scenario | Manual inputs | Sparse media coverage may raise information-acquisition frictions and coincide with higher expected returns. A sudden increase in attention proxies such as Google searches may create short-term retail buying pressure followed by reversal. The horizons differ, and attention measures, firm size and newsworthiness create biases. | No search, social or media data are connected; causality, realised holding periods and capacity are not estimated. |
| Conservative version | Higher threshold | Raise signal/sample thresholds and reduce exposure. | May reduce eligible names. |
| Validation version | Out-of-sample review | Freeze definitions before time-ordered evaluation. | Needs clean, representative data. |
