Sometimes, following a leader makes the best investment strategy. And corporate insiders have long been popular leaders to follow. Their combination of responsibility to their stockholders and access to ‘under the hood’ information on their companies gives their personal investment choices an air of authority.The most important thing about these insiders is that whatever else they do, they are expected to shepherd their companies to profitability. Shareholders want a return on investment, Boards of Directors want accountability, and company officers are held to both standards. So, when they start buying up their own company’s stock, it’s a sign that investors should investigate further.Government regulators, in an effort to level the informational playing field, have required that insiders regularly publish their stock transactions, making it a simple matter for investors to follow them. Even better, TipRanks collates the information in the Insiders’ Hot Stocks page, and provide tools and data filters to easily browse through raw data. We’ve picked three stocks with recent informative buys to show how the data works for you.Del Taco Restaurants (TACO)We’ll start with the popular Del Taco, the California-based taco chain. Del Taco boasts a $344 million market cap, over 600 restaurants, and a loyal fan base, giving it a solid foundation in the fast-food franchise market. Most of the company’s locations are west of the Mississippi, but the company has been making inroads to the eastern US.Like many brick-and-mortar, traffic-dependent businesses, Del Taco has had a hard year. The coronavirus crisis had dampened traffic, social and economic lockdown policies have reduced income streams. The company has started to recover, however. After heavy net losses early in the year, EPS has returned to positive numbers, and revenue in Q3, $120 million, was up more than 15% sequentially.
