The Fund Sentiment Score (fka Ownership Accumulation Score) finds the stocks that are being most bought by funds. It is the result of a sophisticated, multi-factor quantitative model that identifies companies with the highest levels of institutional accumulation. The scoring model uses a combination of the total increase in disclosed owners, the changes in portfolio allocations in those owners and other metrics. The number ranges from 0 to 100, with higher numbers indicating a higher level of accumulation to its peers, and 50 being the average.

In addition to reporting standard equity and debt issues, institutions with more than 100MM assets under management must also disclose their put and call option holdings. Since put options generally indicate negative sentiment, and call options indicate positive sentiment, we can get a sense of the overall institutional sentiment by plotting the ratio of puts to calls. The chart to the right plots the historical put/call ratio for this instrument.

Using Put/Call Ratio as an indicator of investor sentiment overcomes one of the key deficiencies of using total institutional ownership, which is that a significant amount of assets under management are invested passively to track indices. Passively-managed funds do not typically buy options, so the put/call ratio indicator more closely tracks the sentiment of actively-managed funds.
