Apparatus and methods for providing a trading recommendation. The apparatus and methods may involve using information about events and reactions to the events. The events and the reactions may be used to identify an expected impact of the event on a market. The expected impact may be used to recommend investment vehicle trades. The methods may include receiving an information item that relates to an event; receiving a sentiment indicator corresponding to the item; assigning to the item a market impact weighting index that is at least partially based on the sentiment indicator; and, based at least partially on the market impact weighting index, selecting the trading recommendation from a database of trading recommendations.
