As the markets become more and more efficient and finding ideas is becoming more difficult for investors, the style of piggyback investing has emerged. Simply put, 'piggybacking' is following the smart money and making investment decisions based on the publicly-available position sheets of the best investors. By law, the majority of funds are required to release a list of their holdings to the SEC database via 13F-HR filings. Also, activists and any passive investor with a stake greater than or equal to 5% in a given company are required to file 13G or 13D filings. Therefore, it's not very difficult to follow the smart money these days.

Proponents of this school of thought, notably James Altucher of Stockpickr.com and TheStreet.com, argue that it makes much more sense for the individual investor to simply track and cherrypick the best ideas from the smartest investors' portfolios rather than try and interpret news events or randomly sort through stocks. And, for the most part, I tend to agree. As an individual investor, and more importantly a blogger, I constantly struggle to find new and interesting ideas to write about or invest in and I've found that this method has worked well to help me find new potential investments and create interesting watchlists.
