Basically, no. You can look at substantial holdings announcements for 'xyz' and also look at top holdings by individual funds, but that's about it.
Ultimately however, it's not really an actionable idea. For a start, funds will never be holding a single stock. Secondly, equities funds are repriced daily to reflect underlying stock prices of their holdings. So if fund ABC buys stock xyz at $1.00 in January and xyz goes to $2.00 in February, the fund's unit price will reflect that rise. You can't buy Fund ABC in Feb at the price that reflects xyz's Jan price.
The only potential 'free lunch' is buying LICs at a discount to their NTA. But there is no guarantee that the NTA gap will ever close.
